Problem

RSTi-EP is a remote I/&O System composed of I/O slices and a Network adapter. Via this Network adapter the I/O information can be accessed by the Control Unit. Depending on the Network adapter, not only the I/O information, but other registers are available to diagnose the remote state.
EPXMBE001 is a Modbus TCP Network adapter of the RSTi-EP family, which makes available the I/Os and the diagnostic registers by the Modbus TCP protocol. The attached sample shows how to configure the QP+ in order to access the I/Os and all other information the remote unit status provide

Solution

The complete map of the Network adapter is documented in GFK-2958, RSTi-EP User Manual, Chapter 4.4. As general rule:

  • Read Only register, 'ro', are accessed as Input Register (address starting 3x)
  • Read/Write register, 'rw', are accessed as Holding register (address starting 4x)

The attached sample shows an example (with QP+) reading the I/Os, by ModbusTCP Control IO Driver; and the Network Adapter Status and the Modules Status, using the View OPC Driver, through the Modbus TCP driver
