i have a cpu from modicon 140CPU11302 and i need to change the modbus port setting to the followin
baud rate 1200bps
so what loadable should i transfer to the cpu

 

Always read the manual first:
Modicon Quantum
Automation Series
Hardware Reference Guide
Volume 1
840 USE 100 00 Version 11.0 11/2004
- page 111 (PDF page 125) in the middle reads:
===
Setting the slide switch to the bottom position gives you the ability to assign
communication parameters to the port in software; the following parameters are
valid.
===
Folowed by a table that includes 1200 Baud.

If you need the manual that Meir is talking about , you can download it from http://www.telemecanique.com/en/functions_discovery/function_5_11.htm

Click on the quantum and then the button named "library".

I hope it'll help
