Page 32: Process Data
Modbus Gateways - User Guide 5.1.3 Process data The Modbus registers representing the process data of the PROFIBUS devices start with register number 0 for both input data and output data. While the input data is mapped to input registers the output data is mapped to holding registers. -
Page 33: Acyclic Communication
Chapter 5 - Connection to a controller 5.1.4 Acyclic communication The Modbus Gateway has a register-based communication interface for acyclic reading and writing of PROFIBUS device parameters. There are 128 registers reserved per segment. The first 5 registers are control registers which are used to process the command protocol. The remaining 123 registers are used as data registers. - Page 34 Modbus Gateways - User Guide Acyclic writing The controller initiates acyclic PROFIBUS writing by writing a specific command to the control registers of the command interface and writing the data to the data registers. The last data register to be written depends on the length of the data and is calculated as base register + 5 + (data length / 2).

Page 35: High Availibility Registers
Chapter 5 - Connection to a controller 5.1.5 High availibility registers Using a primary gateway and a backup gateway as redundant pair increases the overall availability of a system. The redundant role of a gateway is controlled by the Modbus registers 9990 to 9993. By reading the error state in register 9993 and the status information in register 9991, a redundancy switching mechanism can be implemented in the PLC. - Page 36 Modbus Gateways - User Guide 9992 Holding Register This register represents the detected error state of the gateway which can be used to determine the error conditions. NOTE: Write access for this register is ignored. HighByte: Location HighByte / LowByte : Error state The register content is provided in byte ordering big-endian.
