1-2
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.
