Connecting RS485 Equipment through RS485 Port 2
Upgraded slim type CPU modules can use the RS485 user communication function. Using the RS485 user communica-
tion, a maximum of 31 RS485 devices can be connected to the
MicroSmart
CPU module.
When using port 2 for RS485 communication on the slim type CPU module, mount the RS485 communication module
(FC4A-HPC3) next to the CPU module.
When using port 2 for RS485 communication on the slim type CPU module with the optional HMI module, install the
RS485 communication adapter (FC4A-PC3) to the port 2 connector on the HMI base module (FC4A-HPH1).
Connect RS485 device to the RS485 terminals A, B, and SG of port 2 on the
MicroSmart
CPU module using a shielded
twisted pair cable as shown below. The total length of the cable for the RS485 user communication can be extended up to
200 meters (656 feet).
