The specialists must be familiar with the current norms and guidelines for the devices and automated environments. All changes to the coupler or controller should always be carried out by qualified personnel with sufficient skills in PLC programming. Basic knowledge of the DNP3 standard is also required Use of the WAGO-I/O-SYSTEM 750 in Compliance with Underlying Provisions Fieldbus couplers, fieldbus controllers and I/O modules found in the modular WAGO-I/O-SYSTEM 750 receive digital and analog signals from sensors and transmit them to actuators or higher-level control systems. Using programmable controllers, the signals can also be (pre-) processed. The devices have been developed for use in an environment that meets the IP20 protection class criteria. Protection against finger injury and solid impurities up to 12.5 mm diameter is assured; protection against water damage is not ensured. Unless otherwise specified, operation of the devices in wet and dusty environments is prohibited. Operating the WAGO-I/O-SYSTEM 750 devices in home applications without further measures is only permitted if they meet the emission limits (emissions of interference) according to EN You will find the relevant information in the section Device > Standards and Guidelines in the manual for the used fieldbus coupler/controller.

10 10 Important Notes Appropriate housing (per 2014/34/EU) is required when operating the WAGO- I/O-SYSTEM 750 in hazardous environments. Please note that a prototype test certificate must be obtained that confirms the correct installation of the system in a housing or switch cabinet. The implementation of safety functions such as EMERGENCY STOP or safety door monitoring must only be performed by the F-I/O modules within the modular WAGO-I/O-SYSTEM 750. Only these safe F-I/O modules ensure functional safety in accordance with the latest international standards. WAGO's interference-free output modules can be controlled by the safety function Technical Condition of Specified Devices The devices to be supplied ex works are equipped with hardware and software configurations, which meet the individual application requirements. These modules contain no parts that can be serviced or repaired by the user. The following actions will result in the exclusion of liability on the part of WAGO Kontakttechnik GmbH & Co.

11 Important Notes Safety Advice (Precautions) For installing and operating purposes of the relevant device to your system the following safety precautions shall be observed: Do not work on devices while energized! All power sources to the device shall be switched off prior to performing any installation, repair or maintenance work. Install the device only in appropriate housings, cabinets or in electrical operation rooms! The WAGO-I/O-SYSTEM 750 and its components are an open system. As such, install the system and its components exclusively in appropriate housings, cabinets or in electrical operation rooms. Allow access to such equipment and fixtures to authorized, qualified staff only by means of specific keys or tools. Replace defective or damaged devices! Replace defective or damaged device/module (e.g., in the event of deformed contacts), since the long-term functionality of device/module involved can no longer be ensured. Protect the components against materials having seeping and insulating properties! The components are not resistant to materials having seeping and insulating properties such as: aerosols, silicones and triglycerides (found in some hand creams). If you cannot exclude that such materials will appear in the component environment, then install the components in an enclosure being resistant to the above-mentioned materials. Clean tools and materials are imperative for handling devices/modules. Clean only with permitted materials! Clean housing and soiled contacts with propanol.

12 12 Important Notes Do not use any contact spray! Do not use any contact spray. The spray may impair contact area functionality in connection with contamination. Do not reverse the polarity of connection lines! Avoid reverse polarity of data and power supply lines, as this may damage the devices involved. Avoid electrostatic discharge! The devices are equipped with electronic components that may be destroyed by electrostatic discharge when touched. Please observe the safety precautions against electrostatic discharge per DIN EN /-3.

15 Application General Information about the DNP3 Standard Observe the functions supported in line with DNP3! A list of supported functions for DNP3 is given in the Download area at The DNP3 standard also features the following: The name key for the data point transmission format according to DNP3 consists of group and variation numbers. A sample nomenclature is Here, the 10 represents the group number and the 02 stands for the variation number. Telegrams in the control direction can include more than one command/setpoint. Commands can also activate complex patterns and sequences with repetitions in each telegram. The current statuses of command or setpoint outputs can be queried or read back. Each telegram with user data transmitted from the substation to the master station contains a 16-bit string, which contains status information, for example events at the substation. DNP3 also defines a frozen status for measured values and counters. This enables many or all values to be frozen at a point in time and to then transfer these values to the master station. If the frozen command is issued in a broadcast, values can simultaneously be frozen and then transmitted at several substations. Changes in values at the substation are handled using events. Measured values, counters or messages can be allocated to one of the event classes (1, 2 or 3) or to class 0 (no events). The user can specify the definition of event classes 1, 2 or Task Definition This Quickstart Guide explains how to set up and start a telecontrol substation (server) based on DNP3 with WAGO controllers. The DNP3 Configurator (v or higher) integrated into WAGO-I/O-PRO is used as the configuration program. To check operation, a connection must be established between the controller and PC.

Add these objects to the configuration using the [>] button. The current configuration is presented in a tree structure in this area. The specific parameters for the item that was selected in the Configuration area can be set or changed in this area. Various settings must be made to configure the substation for DNP3. Three different categories of parameters exist for this: Global parameters Parameters for the Link Layer item Parameters for the Application Layer item More information about the individual parameter categories are given in the following sections.

34 34 DNP3 Configurator Specific information about a parameter! When you move the cursor over a parameter, a message text with specific information about that parameter appears at the bottom of the dialog window!

35 DNP3 Configurator Global Parameters Global parameters can be set or changed when the item DNP Outstation is selected. Some of these global settings can be saved in the DNP3 device profile file. A text message at the bottom indicates which global parameters can be saved. Move the cursor over the parameter. The following settings are possible: Figure 20: Setting Options for the DNP Outstation Item Table 12: Setting Options for the DNP Outstation Item Setting Options DNP3 Task The task priority and cycle time with which the generated code is processed at the target system can be specified here. Create var. autom. If this checkbox is marked, the Configurator automatically creates variables. This setting is based on the default setting for all input fields in which variables can be created. Level 2 Conformity If this checkbox is marked, only applications which are DNP Level 2 - compliant can be configured. In this case, some variants cannot be used, such as Analog Inputs in the FLOAT format. Non-supported objects are not displayed in the Configurator. If the checkbox is marked for an existing configuration, the Configurator checks the objects that are used and issues a message if objects in a REAL format have been used. Conversion is possible when the object types have been modified in 32-bit or 16-bit objects.

36 36 DNP3 Configurator Table 12: Setting Options for the DNP Outstation Item Setting Options Hardware version Software version Location Name ID Code/Number Outstation Name Device Serial Number Max. Tx Fragment Max. Rx Fragment Timeout Rx Fragment Max. Ctl. Objects Time synchronization System time Event Buffer Size SBO Timeout Confirm Timeout Std. Command Time Start automatically These parameters have no impact on the functionality of the substation. They are stored in a DNP3 device profile file and can be processed by other systems. This setting is permanently set to 2048 bytes/fragments and cannot be changed. This value corresponds to the maximum possible fragment size based on the standard. This setting is permanently set to 2048 bytes/fragments and cannot be changed. Limiting is not required here, as shorter fragments can be easily processed. The maximum time between two link fragments accepted by the substation is entered here. The maximum number of objects in the control direction that can be processed by the substation is entered here. The time interval after which the substation requests clock synchronization from the master station is entered here. When this checkbox is marked, the time received from a master station is applied to the real-time clock of the target system. The maximum number of event entries that can be stored in the substation is specified here. If events cannot be transferred to the master station and if more events occur than are specified by this parameter, any further incoming events will not be saved. Every link connection uses a separate event buffer. This option requires more memory when the number of entries is increased, or when more link connections parameters are specified. Select and Operate are functions for writing of commands and setpoints from the master to the substation. The maximum time that can elapse between a Select and an Operate is entered here. The substation will only process an Operate when the time between two functions is less that the time entered in this field. Otherwise, a Time-out error is signaled. The substation can request a confirmation for messages that have been sent, for example during transmission of events. The time during which the substation will wait for confirmation from the master station is entered here. If the confirmation is received within the specified time, the event last transmitted, for example, will be deleted from the event buffer. If no confirmation is received, the transmitted events remain in the event buffer and are resent on the next request. The execution time for commands can be specified here. This time is only used when an explicit execution time has been defined for commands from the master station. The DNP3 application is started automatically when this checkbox is marked. The DNP3 application will not start automatically if this checkbox is not marked. The application can read in configuration data from files and assign the corresponding parameters, for example. Once the parameters have been assigned, the variable gxdnp3_enable must be set to TRUE to start the DNP3 application.

Opens the Secure Authentication parameters dialog where the corresponding secure authentication settings can be made. The dialog is described in the following section.

38 38 DNP3 Configurator Secure Authentication Parameter Dialog Secure Authentication is an authentication solution that ensures the integrity of sent/received messages if the function codes used in the telegrams were categorized as critical (e.g., for switching commands). Activation and parameterization of Secure Authentication ensure that the telegrams are transferred from the correct sender and not falsified. Secure Authentication V5, including the Multiple Users, Downloaded Keys, and Symmetric Cryptography variants, is supported in accordance with the DNP3 standard (IEEE1815). The setting options described below are available in this connection. Parameter settings apply to all client connections! The settings made in the dialog apply to all client connections and all connections to higher-level masters. Send critically classified telegrams: Perform Key Change! If critically classified telegrams are to be sent, a so-called Key Change between communication subscribers must be performed in advance. The master must send a corresponding request. This function can be run differently depending on the master used. More information is available in the respective documentation of the master you are using! Perform Key Change : Different steps required depending on parameter settings! Different steps must be performed for the Key Change depending on the setting of the Key handling parameter (see Secure Authentication Parameter dialog: Pre-shared Keys, Symmetric Cryptography setting selected: Perform Session Key Change.

The number of relevant bytes depends on the connection used (serial or ETHERNET). The following options are available: HMAC-SHA-1: Serial connection: 8 bytes ETHERNET connection: 10 bytes HMAC-SHA-256: Serial connection: 8 bytes ETHERNET connection: 16 bytes AES-GMAC: Serial connection: 12 bytes ETHERNET connection: 12 bytes User The number of users can be selected here. A maximum six users is possible. Thresholds Clicking on this button opens another dialog in which the settings for the Security Statistics Objects (group 121/122) can be adjusted (see figure Setting Options for the Threshold Values below). Aggressive Mode If this checkbox is selected, Aggressive Mode of the DNP3 secure communication is used. This mode allows the authentication data to be sent in normal DNP3 telegrams, saving transfer bandwidth. Individual steps are combined into the key exchange. The MAC value is transferred together with the telegram. A challenge reply sequence is necessary once at the beginning of the transfer. If this checkbox is not selected, the default mode Challenge and Reply Messages of the DNP3 secure communication is used.

48 48 DNP3 Configurator Table 16: Setting Options for a Connector Ethernet Object Setting Options Unsolicited Support Event data can also be transmitted without being requested. These are referred to as Unsolicited Responses. Six different options are available for the Unsolicited Responses : Disabled Unsolicited Responses are not transferred. Mode A: Event threshold reached Unsolicited Responses are transferred if the number of events in the buffer has reached or exceeded the event threshold. Mode B: Delay time expired (retriggered) Unsolicited Responses are transferred if there is at least one event in the buffer and the delay time has expired. The delay time restarts as soon as a new event is generated in the buffer. Mode C: Event threshold reached or delay time expired (retriggered) Unsolicited Responses are transferred if the number of events in the buffer has reached or exceeded the event threshold, or if there is at least one event in the buffer and the delay time has expired. The delay time restarts as soon as there is a new event in the buffer. Mode D: Delay time expired Unsolicited Responses are transferred if there is at least one event in the buffer and the delay time has expired. The delay time starts when the first event is generated and is reset upon transfer. Mode E: Event threshold reached or delay time expired Unsolicited Responses are transferred if the number of events in the buffer has reached or exceeded the event threshold, or if there is at least one event in the buffer and the delay time has expired. The delay time starts when the first event is generated and is reset upon transfer. Unsolicited Timeout Unsolicited Retries If one of the modes A to E explained above is selected, the substation actively supports Unsolicited Responses, and the input and output fields described below are active. The master station must confirm Unsolicited Responses. To do this, the master station transmits a corresponding confirmation message to the substation. The amount of time the substation is to wait for this message can be specified here. Value range: 1 s 60 s If the confirmation is received within the specified time, the events are deleted from the event buffer. The message is resent if no confirmation is received within the specified time. Here it is possible to specify the number of times that a message is to be resent if confirmation is not received within the time period specified in the Unsolicited Timeout parameter. Sequence numbers and content are retained in this process. A new message is generated and transmitted as soon as the selected number of transmission attempts is exceeded. Here, the sequence number and, where applicable, the contents are changed.
