8 If the settings are made using a graphic operating unit, then first select the PumpDrive (parameter ) Set a PumpDrive ID between 1 and 6 for the selected PumpDrive (parameter ) PumpDrives with no set PumpDrive ID are not detected in the Profibus network PumpDrive must be reset after parametrising for all set values to be applied To do this, call up parameter Please note: The start bit for multi--pump operation mode is set in the Profibus card (see Issue, page 13) 255 Activating fieldbus control In order for the Profibus module to forward data to the PumpDrive, the fieldbus control must be activated in the PumpDrive with installed Profibus module Activate the fieldbus control (parameter ) When fieldbus control is deactivated, data can only be read by the PumpDrive Access to the system parameters via the Profibus is dependent on the login level: D System parameters can only be read or written when their login level is defined in the device description file (see chapter 3, page 8) D Access to a system parameter is not permitted when login level information is missing (e g when no pump is connected) 256 Setting the baud rate The baud rate must be set on the Profibus master It is detected automatically by the Profibus module and can be set to a maximum of 12 MBaud 3 Loading the device description file The PumpDrvgsd device description file is delivered with the Profibus module on a CD--ROM, and must be imported with the corresponding configuration program for the Profibus network The PumpDrive with Profibus module is then detected as a slave device in the Profibus network The following program modules can then be loaded using the configuration program: D Profibus module -- Allows the exchange of I/O cycle data between the Profibus master and Profibus module D PumpDrive -- Allows the exchange of I/O cycle data between the Profibus master and PumpDrive in single pump systems (or PumpDrives in multi--pump systems) D Asynchronous msg -- Allows the asynchronous exchange of data between the Profibus master and PumpDrive(s) (i e read and write on request) See chapter 4, page 11 for a detailed description of the modules 31 Setting the Profibus master with the configuration program The following rules must be observed when setting using the configuration program: D The Profibus module can only be added once D The PumpDrive module can be added up to six times (e g one module for each drive connected over the KSB local bus when in multi--pump operation) D The Asynchronous msg module can only be added once The Profibus module cannot send any data when these rules are not adhered to Example 1 The following modules are added in sequence using the configuration program: D Profibus module D PumpDrive D PumpDrive D PumpDrive The data for the Profibus module, pump 1, pump 2 and pump 3 are then available in sequence on the input/output memory of the Profibus master 8

9 Example 2 The following modules are added in sequence using the configuration program: D Asynchronous msg D Profibus module D PumpDrive D PumpDrive D PumpDrive The first part of the I/O memory is then reserved for the asynchronous message log If a module from a non--existing-pump is loaded, then the corresponding I/O data cannot be read out (e g module for pump 3 is loaded, but no pump is connected to the KSB local bus with the PumpDrive ID 3) 311 Setting data points for specific PumpDrive IDs If the PumpDrive module is loaded repeatedly, then the data points are automatically numbered in sequence to pump 1, pump 2, pump 3 and so on However, the PumpDrive modules can also be assigned to a specific pump in a multi--pump system To do this, the User_Prm_Data_Len and User_Prm_Data parameters must be adjusted in the PumpDrvgsd device description file Parameters can be adjusted directly in most configuration programs for Profibus networks Alternatively, the PumpDrvgsd device description file can be adjusted using a text editing program Proceed as follows to set specific PumpDrive IDs: D Set the number of PumpDrives in the User_Prm_Data_Len parameter D Set the PumpDrive IDs in the User_Prm_Data parameter Example When loading four modules, the following settings must be made so that PumpDrive can assign the data points in the correct order to the PumpDrives with the IDs 1, 3, 5 and 6 D User_Prm_Data_Len parameter = 4 D User_Prm_Data parameter = 0x01, 0x03, 0x05, 0x06 Example: Single -pump operation Bytes Asynchronous messages 0 9 Profibus card PumpDrive

18 Task code The task code identifies the measure The following are valid codes: Task Measure Description code 1 Read For reading variables whose index is specified in the Index field 2 Write For writing the values from the Value field to the variable whose index is specified in the Index field Table 20: Task codes An answer contains the same value in this field Index The Index specifies the hex addresses of the variables to be read or written An answer contains the same value in this field S (save bit) When a write request is made, it must be specified if the value to be written is a parameter that should be stored permanently in a non--volatile memory When the S field is not set, then the value to be written is only stored in the volatile memory (RAM) An answer contains the same value in this field Value The Value field can be set by the Profibus master to 0 in the event of a read request When the answer to a read request is E = 0, then the Value field contains the read out value of the variables The Value field contains the value of the variables to be written in the event of a write request When the answer to a write request is E = 0, then the Value field retains the variable values in case the value needs to be sent to the device again When the answer to a write request is E = 1, then the Value field contains one of the following error codes ERROR CODES Code Meaning 1 Invalid task code 2 Invalid data index 3 Invalid data value 4 Error in slave device (PumpDrive) 6 Slave device (PumpDrive) occupied 11 Access destination not available 65 Device is in boot mode 80 The device is not online 81 Access denied 82 The fieldbus control is deactivated 83 Access not permitted, the parameter has the Service or Plant login level Table 21: Error codes 18

19 423 Guidelines for processing requests / answers The Profibus master sends requests to a slave device (PumpDrive), which reacts with a correct answer Each request from the Profibus master is connected to one single answer from the slave device A slave device (PumpDrive) cannot send data to the Profibus master without a valid request Profibus master Request Request Request PumpDrive with Profibus module Answer Answer Fig 5: Request / answer system The Profibus master does not send further requests until it has received an answer to a prior request A request from a Profibus master is made as follows: D The data is written to the output area D The TID value is increased D The Profibus master waits for an answer from the PumpDrive in the input area D As soon as the Profibus master in the input area reads a TID value as an answer which corresponds to the TID value of the request, then it reads out the input area with the answer 43 Additional notes When the following is set, the entire database of system variables can be accessed in read and write mode: D N login level (no login) or C login level (customer) D for write operations, fieldbus control active on PumpDrive (parameter ) Commands to the Profibus module can also be sent using the Task code field as an alternative to the command bits To do this, set the task code to 2 (write) Commands from the following address areas can then be used: D 0x x461F -- Commands to the Profibus module according to bits of the cyclical output commands D 0x x463F -- Reset of an individual alarm in the Profibus module according to the reset for alarms A command is set to ON or OFF by writing 1 or 0 in the Value field 431 Example: Reading out the kwh meter To read out the kwh-meter, proceed as follows: Output data from Profibus master: 1 Byte 1 (destination): Set bit 0 to 1 (dez 1), for PumpDrive ID 1 2 Byte 2 (task code): Set bit 0 to 1 (dez 1), for write commands 3 Byte 3 (index): Enter the kwh hex address (41DC) for read commands 4 Byte 0 (TID): Increase the value by 1 to execute the read command Input data from Profibus master: 5 Byte (value): Read out the value from hex address 41DC Also select the PumpDrive ID: e g PumpDrive 19
