The DCS System need to get data in PLC such as status Pump--- status Temp.. and Etc... i will setting PLC Q00 CPU with Qj71MB91 in Slave Mode but this module i never use it before. I want to know ? how to setting when use intelligent function in Software GXworks2

For slave mode you only need to initialize the module with the correct baudrate and bit settings, and station number. Then the Master device can basically read out status from the PLC... Check the quick start in the manual and let us know if you run into problems...

What are your switch settings in GX Developer for the module? You can download the manual from the Mitsu website. Just search for QJ71MB91...
