Communicating two Mitsubishi PLCs with RS485BD


Thread Starter

We are using Mitsubushi Series FX2n PLCs with RS485BD. Can we communicate two PLCs with the above configuration (RS485 ie OPEN Protocol). Or it require to write some separate Driver Software.

I am not sure if I quite understand but I have successfully written the ladder program to have two FX2N's communicate with each other. I used the BD board as well. I used to be an app engineer for a mitsi distributor and there are a couple of choices for communication formats. I reccommend calling your distributor and asking for the "Communications Manual" I can't remember the exact name but they should know.
