6 Introduction Purpose of the Manual The Scheduler configuration tool is a tool designed to enhance and facilitate the scheduling functions of your control network. The Scheduler configuration tool functions as a stand-alone tool and can be run from any free programmable controller, from our Display devices as well as from our Scheduler device. The true advantage of the Scheduler configuration tool is that it can broadcast schedules over the entire control network, using network variables, for other controllers to use. This saves on programming time as only one schedule is required for all the controllers on the network Each schedule includes a template for every day of the week with a capacity of up to six events per day. For added flexibility there are four special day templates per schedule for holidays or other exceptional events. Intended Audience The Scheduler configuration tool user guide is intended for system designers, integrators and field technicians who have experience with control systems. It is recommended that anyone installing and configuring an Scheduler configuration tool have prior training in the usage of these products. Short Description of Manual Sections Installing and Launching the Scheduler Configuration Tool - This chapter is intended to provide the user with a basic instruction on how to install and launch the configuration. Schedule Programming Quick Start - This chapter is intended to provide the user with a quick instruction on how to quickly configure a schedule through the Scheduler configuration tool and through a Display device. Scheduler Configuration Tool - This chapter is intended to guide you through the step-bystep configuration of the Scheduler device s configuration tool. This chapter follows the same organization as the configuration tool itself, in order to help you configure the device in a logical fashion. This section also serves as the main reference for each option of the configuration tool. 6 Scheduler Configuration Tool

15 3. SCHEDULE PROGRAMMING QUICK START This chapter provides instructions on how to quickly set up a basic schedule through the Scheduler configuration tool and through a Display Device. In This Chapter Topic Scheduler Configuration Tool Quick Start 16 Schedule Programming through a Display Device 19 Page Scheduler Configuration Tool 15

16 Schedule Programming Quick Start Scheduler Configuration Tool Quick Start This section will describe how to quickly set up a schedule through the Scheduler configuration tool. For more information on the different modules of the configuration tool refer to Scheduler Configuration Tool. 1. Launch the Scheduler configuration tool as described in Launching the Configuration Tool. 2. Select the Week Schedules module from the Menu window of the Scheduler configuration tool. 3. Select the desired day to configure from the Select Day drop-down menu. Enter a time in the Time field and an enumeration state from the Enumeration drop-down menu. Figure 3-1 shows a scheduling example for the Monday of every week. In this example the 8:00 to 12:00 shift is configured as Event 1. The 13:00 to 18:00 evening shift is configured as Event 2. Figure 3-1: Sample Monday schedule 4. Configure the rest of the days of the week in a similar manner. Identical schedules can be setup for different days by clicking the Copy button in the configured day, selecting another day from the Select Day drop-down menu and clicking the Paste button. 5. Select the Special Day Schedules module from the Menu window of the Scheduler configuration tool to configure holiday or special day schedules. There are four special day schedules that you can configure. 16 Scheduler Configuration Tool

17 Schedule Programming Quick Start 6. Select the special day from the Special Day Schedules drop-down menu. To change the name of the special day, click the [ ] button next to the menu. Enter the name of the special day and click OK. Figure 3-2: Changing the default name of the Special Day 7. Configure the special day by entering a Time and state (Enumeration ) as in the Week Schedules window. Figure 3-3: Changing 8. Select the Calendar module from the Menu window of the Scheduler configuration tool. 9. Click Assign Schedule under Calendar Mode. Select the special say you wish to assign to your calendar by selecting it from the Select Special Day drop-down menu. 10. Browse the months by clicking on the Next and Previous buttons. Once you have found the month and day where you would like to assign your special day simply click on it with your mouse and a grey number will appear which corresponds to the Special Day Schedule you have selected in the Special Day Schedules drop-down menu. So if you have selected special day 1, then the number 1 will appear in grey on the day you selected in the calendar as shown in the figure below. Scheduler Configuration Tool 17

18 Schedule Programming Quick Start Figure 3-4: Assigning the Special Day to the Calendar module 11. Select View Schedule under Calendar Mode. Confirm the accuracy of the schedules by selecting a day in the calendar and checking to see if the appropriate day schedule appears. Click OK. Schedule 1 is now ready to use. Now all that is left is to assign to schedule to the appropriate device. To use it in a GPI code, simply drag and drop a Schedule block into a project and assign it block number 1. Assigning the Schedule to a Free Programmable Controller Use the reserved word Schedule1 to insert the schedule you have just configured into your code (if you are using the Scheduler configuration tool on the same controller you activated the configuration tool from). Otherwise bind nvoschedule1 to the appropriate NVI on the destination controller (the one that is to follow this schedule). Assigning the Schedule from a Display Device There are 16 schedules supported by the Display device, and since there is no code tool in the Display device the only way to use the schedules is to bind the proper NVO (there is one per schedule, so for Schedule1 it is nvoschedule1) to the proper NVI on the destination controller. 18 Scheduler Configuration Tool

19 Schedule Programming Quick Start Schedule Programming through a Display Device Display Device Functionality Figure 3-5: The Display module front panel The Display device has a simple to use and easy interface. It consists of the following buttons: X (Exit) Button (Left) Button (Up) Button (Down) Button (Right) Button Click this button to go one screen back and the changes you made in the original screen will not be made.

By default the WEEKLY SCHEDULE menu will be selected. Press the button. 5. Press the button and then use the buttons to navigate through the available schedules. There are sixteen schedules available. They are marked SCH1 through SCH16. Once you have selected the schedule you would like to configure, press. 6. Press the button and then the button to select which day of the week to be configured in your current schedule. Use the buttons to navigate between the days. Once you have selected the desired day of the week, press. 7. Press the button and then the button and you will be in the time field of Event 1 which is written e 1 on the Display device s screen. Press the button. Now use the buttons to determine the first digit of the starting time of your event. This digit is either 0 or 1 (remember military time is used). Press the button to move the cursor to the second digit of the starting time. Again use the buttons to select the appropriate digit (from 0 to 9). Repeat the same step to configure the 3 rd and 4 th digits of your event starting time (they represent the minutes, whereas the first and second digits represent the hour). Once you have selected the proper time press the button. 8. Press the button and you will be in the state field of Event 1. Press the button. You can now select the state you want the schedule to be in during this event. Use the buttons to navigate between the states. The states that you can select correspond to the SNVT type of your network variable (configured through the Scheduler configuration tool). Once you have selected the SNVT type push the button. 9. Configure all the events in all the days of the week in your schedule by repeating steps 4 to To configure a special day schedule, go to step 4 and instead of selecting WEEKLY SCHEDULE select SPECIAL DAY and then repeat steps 5 to Scheduler Configuration Tool

21 4. SCHEDULER CONFIGURATION TOOL This chapter guides you through the step-by-step configuration of the Scheduler configuration tool. This chapter follows the same organization as the wizard itself, in order to help you configure the configuration tool in a logical fashion. This section also serves as the main reference for each option of the configuration tool In This Chapter Topic Calendar 22 Week Schedules 24 Special Day Schedules 27 Options 29 Data Manage 35 Object Manage 37 Message Logger 38 Page A schedule can also be configured through an HMI or Display device. Scheduler Configuration Tool 21

22 Scheduler Configuration Tool Calendar This is the first screen that appears after launching the Scheduler configuration tool. The user may also access this screen by clicking Calendar from the Menu window on the left hand side of the configuration tool. Figure 4-1: Calendar window Calendar Mode View Schedule Determines the functionality of the Calendar. There are two options here: View Schedule Assign Schedule By selecting this option in Calendar Mode, the user will be able to view the daily schedules configured for this schedule. By clicking on any day in the calendar the user will be able to see all the events configured for that particular day of the week. The time and status of the schedule will be displayed on the right hand side of the schedule. The Next and Previous buttons are used to browse the months of the year. Clicking the Today button takes you automatically to the current day, month and year. 22 Scheduler Configuration Tool

23 Scheduler Configuration Tool Assign Schedule This option in Calendar Mode allows the user to assign a Special Day Schedule to a day on the calendar. This is done by first selecting the Special Day from the Special Day Schedules dropdown menu that appears to the right of the calendar as soon as the Assign Schedule mode is selected. There are four special days available for configuration. Their default names are Holiday 1 through Holiday 4. They are also numbered 1 through 4. (The numbers appear in brackets next to the special day). If you have not yet configured your special day schedules, clicking on the > button to the right of the menu will take you to the Special Day Schedules module. After you have configured and selected your special day schedule, click on the day in your calendar that you would like to assign the special day schedule to. The number of your special day (the one in between brackets) will appear in grey. Use the Next and Previous buttons to navigate through the months of the year. Clicking the Today button takes you automatically to the current day, month and year. If you are configuring a special day which is a day of the week and is also a date then you will have to do so once a year. This is because the controller will only process dates. Example: If you configure the first Monday in September to be a special day in 2007, then you will have to change the schedule once you are in Because in 2007 the first Monday in September is the 3rd and in 2008 the first Monday is September 1. Therefore if in 2008 you do not change your schedule to mark your special day on the 1st, then the controller will assume that the special day is still the 3rd of September regardless of which day of the week it is. Scheduler Configuration Tool 23

24 Scheduler Configuration Tool Week Schedules This module is used to configure the schedule for every day of the week. It is accessible through the Menu window on the left-hand side of the configuration tool. The screen shown below will appear. Figure 4-2: Week Schedules window To configure a particular day, select that day from the Select Day drop-down menu. You can also browse through the days by using the Next and Previous buttons. Clicking the Apply button will confirm the changes you have made to the schedule. Clicking OK will confirm the changes to the schedule and close the Scheduler configuration tool. If you would like to use the same events for different days of the week, simply click the Copy button on one configured day, go to the new day you would like to configure and click Paste. This will copy all the parameters from one day to another. Once you have selected the day you wish to configure, you may start defining the events for that day. This is done by entering a Time and Enumeration (state) for each event. For advanced users the Value field is also available. There are six events available for each day. 24 Scheduler Configuration Tool

25 Scheduler Configuration Tool Time This is the time at which the event will start and the event preceding it will end. All times should be entered in military time (00:00 to 23:59). For example, Event 1 can be the morning shift, which starts at 08:00. Event 2 can be the lunch break, which starts at 12:00. This way Event 1 lasts from 08:00 till 11:59. event. To do overnight schedules (useful for outdoor lighting applications) simply enter the start event and the finish Example: You would like your event to start at 6 PM Monday and end at 6 AM Tuesday. Enter an event that starts at 18:00 on Monday, go to the Tuesday schedule and enter another event to start at 6:01. The controller works on an event by event basis, so an event will not stop until another one is scheduled to start. Value (Advanced Users) Advanced users can use this field to determine the Enumeration of the event or to send data across the network. The field accepts any value from 0 to 255. Refer below for the exact values of states for SNVT_tod_event and SNVT_occupancy. Enumeration: Value: OC_OCCUPIED 0 OC_UNOCCUPIED 1 OC_BYPASS 2 OC_STANDBY 3 NO_EVENT 255 Entering the values displayed above is the equivalent of selecting the enumeration for the event. So if Event 1 is given a value of 0 then it is also given an enumeration of OC_OCCUPIED. To send data over the network users must be careful as to what type of data they are sending and in what format they are sending it. The scheduler configuration tool can send data over the network in SNVT types of 1 or 4 bytes. Two byte SNVT types are not supported by the Scheduler configuration tool at the moment. This is why we recommend using the recommended SNVT types. If the SNVT type is changed, the enumerations may change. Therefore, users should verify the value of the enumerations whenever the SNVT type is changed. Refer to Options to learn more about SNVT types and how they apply to the Scheduler configuration tool and to sending data over the network. Scheduler Configuration Tool 25

26 Scheduler Configuration Tool Enumeration This drop-down menu corresponds to the SNVT type to which the configuration tool is configured. The default type is SNVT_tod_event. All the enumerations available for this type are listed above. The enumeration is essentially the state the controller will enter upon receiving the update from the schedule to do so. So if Event 1 is configured to have an enumeration of OC_OCCUPIED at 12:00, then at 12:00 the controller receiving the schedule will go into occupied mode. The user can then customize what happens during the occupied mode using a device s configuration or programming tool. 26 Scheduler Configuration Tool

27 Scheduler Configuration Tool Special Day Schedules This module is similar to the Week Schedules module except that it is used to configure Special Days as the name suggests. The screen shown below will appear. Figure 4-3: Special Day Schedules page of the Scheduler configuration tool The configuration process is the same as in the Week Schedules screen. Simply select the special day to be configured from the Special Day Schedules drop-down menu. The days can also be browsed through by using the Next and Previous buttons. The special days are named Holiday 1 through Holiday 4 by default. To change the name of a special day, click the [ ] button directly to the right of it. This will display a window prompting the new name for the special day to be entered. Figure 4-4: Special Day name change window Click OK to confirm the change and close this window. Click Cancel to close the window without confirming the change. After selecting the Special Day you wish to configure, simply enter a Time and Value or Enumeration for each event you would like to have in your special day schedule. Scheduler Configuration Tool 27

28 Scheduler Configuration Tool The Copy button may also be used to copy all configured parameters of the configured special day and the Paste button can then be used to apply those copied parameters to another special day. Clicking on the Apply button will confirm the changes you have made to the schedule. Clicking OK will confirm the changes to the schedule and close the scheduler configuration tool. 28 Scheduler Configuration Tool

29 Scheduler Configuration Tool Options The Options module contains the configuration parameters for the Scheduler configuration tool output. You can access this window by clicking on Options from the Menu window on the left hand side of the configuration tool. Figure 4-5: Options window Scheduler Configuration Tool 29

30 Scheduler Configuration Tool Figure 4-6: Options window (GPI) Each schedule object has a dedicated NVO for it to transmit its contents over the network. The number of schedule objects available is dependant on the device being used. In addition to this, programmable controllers using the GPI tool have a dedicated NVI for it to receive a schedule over the network. In order for the information to be propagated over the network using these NVOs or NVIs, the NVOs must be bound to the proper NVIs on the receiving controllers and the NVIs must be bound to the proper NVOs on the transmitting controllers. The binding of variables is done using a network management tool. Refer to their respective user guides for more details on how to bind network variables. Scheduler Name Enter the name of the Scheduler object (maximum 85 characters). Scheduler Output Configuration Update Period Default Value This is a user defined interval which is the rate at which the schedule object will send out the value of the schedule to the network. The value must be entered in seconds. It is not advised to put a very low update period so as not to flood the network with data. This is the value that the schedule will take when an override is activated. The user may select from a drop-down menu of enumerations. The enumerations change according to the selected SNVT type. Refer to Object Manage for more details on override. 30 Scheduler Configuration Tool

31 Scheduler Configuration Tool NV Type All network variables (input and output) have a Standard Network Variable Type (SNVT) type. This type determines the format and enumeration and/or resolution of the network variable. In effect the SNVT types determine what the network variable can or cannot do. The default SNVT type used for nvoschedulex (for example, nvoschedule1) is SNVT_tod_event. This is a 4-byte SNVT type and it will display the current state, next state and the time remaining till the next state goes into effect. So if nvoschedule1 is viewed using a network browser or management tool, it would display something like this: OC_OCCUPIED, OC_UNOCCUPIED, 60 This means that the current state of Schedule 1 is OC_OCCUPIED, the next state of Schedule 1 is OC_UNOCCUPIED and that there are 60 minutes remaining till the next state takes effect. It is possible for the user to change the SNVT type; this is done by clicking on the Change Type button. Change Type This button is used to launch the Change Network Variable Type window. This button is only available in LNS. To use this option in NiagaraAX, refer to Change Network Variable Type (NiagaraAX). NV Value Read Value The current value of the NVO (read only). This button only works if the device is configured, online and attached. This button can be used to retrieve the current value from the network. Scheduler Configuration Tool 31

32 Scheduler Configuration Tool Scheduler Input Configuration (GPI only) Max Receive Time The maximum time period between received updates of the network variable on the network (whether or not the variable's value has changed). The maximum receive time is also known as the heartbeat. Setting this to zero disables this feature. When enabled, we recommend setting for this value is twice the max send time configured for the corresponding network variable output. A max receive time failure occurs if a network variable update is not received on the network within the time period set in the textbox. On a max receive time failure, the device will go into alarm, the device status will be updated to indicate a failure, and the NVI will return to its default value. The appropriate alarm and status bits will be updated on a max receive time failure. Max receive time only applies to NVIs that are bound. NV Type All network variables (input and output) have a Standard Network Variable Type (SNVT) type. This type determines the format and enumeration and/or resolution of the network variable. In effect the SNVT types determine what the network variable can or cannot do. The default SNVT type used for nvischedulex (for example, nvischedule1) is SNVT_tod_event. This is a 4-byte SNVT type and it will display the current state, next state and the time remaining till the next state goes into effect. So if nvischedule1 is viewed using a network browser or management tool, it would display something like this: OC_OCCUPIED, OC_UNOCCUPIED, 60 This means that the current state of Schedule 1 is OC_OCCUPIED, the next state of Schedule 1 is OC_UNOCCUPIED and that there are 60 minutes remaining till the next state takes effect. It is possible for the user to change the SNVT type; this is done by clicking on the Change Type button. Change Type This button is used to launch the Change Network Variable Type window. This button is only available in LNS. To use this option in NiagaraAX, refer to Change Network Variable Type (NiagaraAX). NV Value The current value of the NVI (read only). 32 Scheduler Configuration Tool

33 Scheduler Configuration Tool Read Value This button only works if the device is configured, online and attached. This button can be used to retrieve the current value from the network. Change Network Variable Type (LNS) The Change Network Variable type window is typically used when there is a need to modify the variable type before creating a binding. The NV type should be changed BEFORE configuring the schedule. Figure 4-7: Change Network Variable Type Window Network Variable Name Actual Type Preferred type list Length The name of the network variable. The current network variable type. When the type is changed and Apply is clicked, this field will be updated. Checking this box will show the preferred type list for the network variable. This option is selected by default. The preferred type varies based on the type of input and displays the most appropriate SNVT types that should be attributed to the network variable. The preferred SNVT types for nvoschedule are: SNVT_hvac_mode SNVT_occupancy SNVT_tod_event Select Equal length only to only list network variable types that have the same length as the Actual Type. Select All to list all network variable types that do not exceed the maximum NV length. Scheduler Configuration Tool 33

34 Scheduler Configuration Tool Type files Type list A list of all available type files from the device resource file catalog (standard and manufacturer defined). Based on the.typ file you select, the Type List will change. A list of types within the selected file that are of the appropriate length. Change Network Variable Type (Niagara AX ) The Changeable Nv Manager view is typically used when there is a need to modify the variable type before creating a binding. Each variable type has a preferred number of SNVT types and these preferred SNVT types will work best with the selected variable type. The supported SNVT types for nvoschedule are: SNVT_hvac_mode SNVT_occupancy SNVT_tod_event The NV type should be changed BEFORE configuring the schedule. To change a network variable type using the Changeable Nv Manager view, follow these steps: 1. Enter into the Changeable Nv Manager view by right-clicking the device name and selecting Views Changeable Nv Manager. Figure 4-8: Changeable Nv Manager View 2. Select the NV whose type is to be changed. 3. Click the Edit button (the Edit Nv Type window will pop up). 4. From the drop-down menu, select the new SNVT type and click OK. Figure 4-9: Edit Nv Type Window 34 Scheduler Configuration Tool

35 Scheduler Configuration Tool Data Manage There are two main sections in the Data Manage module: Figure 4-10: Data Manage Window (LNS) Figure 4-11: Data Manage Window (Niagara AX ) Scheduler Configuration Tool 35

36 Scheduler Configuration Tool Data Management Import (LNS only) This command enables the user to import a schedule from any other controller on the same network that has a scheduler object. Simply select the controller that the schedule you wish to import is stored on and click OK. After doing this all the settings in the configuration tool will be changed to that of the imported settings. Figure 4-12: Import schedule data source window Clear By clicking on this button the users returns all configuration tool parameters to their default values. Synchronization Upload Download Clicking on this button will upload all schedule settings stored on the controller and apply them to the schedule configuration of the configuration tool. Useful if you would like to see what schedule your controller is running on. This button will send all schedule configuration data from the configuration tool to the controller. Used to make changes to schedules. It should be noted that clicking the Apply button will make the same changes, as will the OK button. 36 Scheduler Configuration Tool

37 Scheduler Configuration Tool Object Manage This module of the Scheduler configuration tool is used to perform certain object requests on your device. Figure 4-13: Object Manage Window Get Status Clear Status Override ON Override OFF Enable Disable Request Display Active Only Used to update the device status as opposed to waiting for the update period to expire.

38 Scheduler Configuration Tool Message Logger This tool displays errors and warnings as soon as they occur. The errors remain in the log until the user clears the log by clicking the Clear button. The Close button closes the message logger without erasing the errors. The user can also save the message log to a file by clicking the Save to File button. The user is notified to the presence of an error in the main window of the configuration tool by the book icon turning red. This means that there are logged errors ready for viewing. The book icon will only return to its default grey color after the errors have been erased. Selecting the Don t show information automatically option in the Message Logger will prevent it from popping up every time there is an error. Figure 4-14: Message Logger The Save to File function can be used to save a message log which can then be sent to Technical Support for more efficient and accurate responses. 38 Scheduler Configuration Tool
