The 8 Series relays have a two-stage communications capability. The base CPU supports
Modbus protocol through the Ethernet, USB, serial and WiFi port. In addition, the base CPU
also supports IEC 103, DNP serial, DNP TCP/IP, and TFTP protocol. Once the
communications module option is added to the base, the base Ethernet port becomes
disabled but the two Ethernet ports on the communications module have enhanced
communications capabilities such as IEC61850, IEC62439 parallel redundancy protocol
(PRP) and IEEE 1588 Precision Time Protocol (PTP). The communications CPU also supports
Modbus TCP, IEC 104, DNP TCP, TFTP, SFTP, and SNTP protocol.
On the rear card 8 Series relays are equipped with one RS485 serial communication port
and one 10/100 Mbps Ethernet port. The RS485 port has settings for baud rate and parity.
It is important that these parameters agree with the settings used on the computer or
other equipment connected to this port. A maximum of 32 relays can be daisy-chained
and connected to a DCS, PLC or a PC using the RS485 port.
