Register Overview
Here you get a general overview of the Modbus addressing of the modules, which are currently on
the backplane bus. The addresses of the registers for bit or word access are shown for each module.
It is shown in hexadecimal form – decimal in brackets. Normally the access with Modbus happens by
means of the ranges 0x, 1x, 3x and 4x. The following assignment is valid:
•
0x – Bit area for master output
Access via function code 01h, 05h, 0Fh
•
1x – Bit area for master input
Access via function code 02h
•
3x – Word area for master input
Access via function code 04h, 17h
•
4x – Word area for master output
Access via function code 03h, 06h, 10h, 16h, 17h
