HMI Connectivity to our FA-M3 PLC
We have our Range of PLC's FA-M3 for Factory automation. Now we want to connect a HMI to our PLC. But the HMI manufacturer does not have a driver for our PLC. His HMI's can be connected as modbus master or Slave. but we dont have Modbus modules. Is there any standard modbus program to be written to the PLC to make the RS-485 port to work on modbus protcol. If yes, anybody having standard program can you mail me back.
PcVue HMI supports for FA-M3 series: serial communication protocol through the CPU Board port and TCP/IP protocol through a specific module. Please check our web site http://www.arcinfo.com or send me directly an e-mail at p.bailliencourt@arcinfo.com if you need more information.
