FP Web-Server V2.11

12.1 Overview on Modbus-TCP Functions of the FP Web-Server

 

 

For an overview on all functions, please refer to the block diagram (see page 10).

1.This function uses the 2nd RS232C (9-pin Sub-D connector).

2.Since Modbus protocol, in contrast to the PLC, only recognizes 4 different memory areas, a configurable Address-Translation-Table was implemented. This allows you to configure offsets so that Modbus "coils" and "registers" correspond to the PLC's memory areas: X, Y, R, DT, FL, WR, etc.

3.Various functions can be combined and used simultaneously.

4.Most functions support the same list of Modbus function codes.

5.You can configure all these functions manually or with the help of the wizard.
