Hello ,
I'm using DVP12SE11R Delta PLC .
I would like to read data from an external device using RS485 communication.
In the WPLSOFT i have informed that i gotta use MODRD command in order to read the data . but i am not sure how to use it properly.
the data is formed as one bit ('1' or '0') i wanna read 10 registers using MODRD although those registers are not ordered one after another and i know MODRD can read 6 registers one after another.
Then i would like to use that bit as a Normally Open contact in the WPLSOFT and turn on a coil.
i would like to get some help with it.
thanks.
