Communication ports
XS series generally has COM1 (RS232), COM2 (RS485) and 2 LAN ports (RJ45). COM1 and COM2 are
mainly used for communication. Ethernet port can connect PLC to LAN or realize EtherCAT communication.

LAN port
Ethernet RJ45 port: the Ethernet port is RJ45 interface, with stable and convenient communication mode. It can
be used for uploading and downloading programs, online monitoring, remote monitoring, etc., and can
communicate with other TCP IP devices in the LAN.
EtherCAT communication port: the EtherCAT communication port is an RJ45 interface with convenient
communication connection mode and can communicate with other equipment supporting EtherCAT
communication.
(4)
CAN port
On the output terminal block, the terminals are GND, CAN+ and CAN-, which can communicate with other
devices that support CANopen communication.
