I am using a Mitsubishi Melsec FX2N-80MR PLC and a FX2N-232IF communication module. I want to change the baud rate from 9600 to 19200 and parity from even to none. Does anybody know how to do this? This is the first time I am using a PLC. I am a programmer and I know nothing about PLC's. I have an Engineer who knows how to use Medoc, but he doesn't know how to change the baud rate nor the parity. Any help would be appreciated.

 

The interface software has the facility to set the communication parameters setting.
Using that U can define U R necessary communication settings asper U R driver.

 

The Communication module that you are using contains "Buffer memory addresses" To change the communication parameters you need to send the correct values to these locations, If you look in your program you will see some TO and FROM and some RS commands that are setting up the card.
