Parameter access via Modbus/TCP

The Modbus Protocol (Modbus/TCP)

8.4

Parameter access via Modbus/TCP

A parameter access via the MOVILINK

®

 parameter channel in registers 200

hex

  203

hex

via Modbus/TCP requires the services FC3, FC16 or FC23 (write and read access).
Write access is used for storing acyclic requests in the corresponding registers. Read
services read the responses from the same registers. 
This method corresponds to the alternative concept according to the Modbus specifica-
tions (appendix A) 'Network Messaging Specification for the MODBUS/TCP Protocol:
Version 1.1". 

8.4.1

Procedure with FC16 and FC3

The respective error code is generated if a write access is incorrect (see section 'Error
codes (exception codes)'). In this way, the write services are already processed by
sending a 

Write request

 (FC16), and the service confirmation can be carried out by eval-

uating the 

Write response

. Later on, the master will send a 

Read Request

 (FC03) in or-

der to read out the values that have now been written into the register.

8.4.2

Procedure with FC23

With FC23, the result is returned directly in the response.
