RS485-1 is the extension port of ELC-12 CPU(new version) named COM2 ,it usually servers as
extension port , but it also can be used as common RS485 port if no any extensions need use
in your application and at the same time two RS485 ports need be used. The standard RS485
module cannot bring out the terminals of COM2 built-in ELC-12 series CPU,
so one customize
RS485 module should be used for this case.
RS485-2 is the common RS485 port built-in ELC-12 series CPU ,ELC12-E-RS485 module is
used to bring out the terminals from this port named COM3. Additionally ,ELC12-E-ETHERNET
module is also using this port to connect with ETHERNET.

Example: The following we'll take a example that one xLogic (Master) communicate with other
xLoigc (Slave) via RS485.
