ACE969 Multi-Protocol Communication Interface Installation Sheet, Instruction Bulletin (ANSI), 63230-216-235A1, May 2007
The ACE969 multi-protocol communication interfaces function with Sepam Series 20, 40, or 80. They have two communication ports to connect a Sepam to two independent communication networks:
The S-LAN (Supervisory Local Area Network) port to connect Sepam to a supervision network using one of the three following protocols:
IEC 60870-5-103
DNP3
RTU Modbus
The communication protocol is selected when setting Sepam parameters.
The E-LAN (engineering local area network) port, reserved for Sepam remote parameter setting and operation using the SFT2841 software
There are two versions of the ACE969 interfaces. Each has different S-LAN ports:
ACE969TP (Twisted Pair) is for connecting to an S-LAN network using a two wire RS485 connection
ACE969FO (Fiber Optic) is for connecting to an S-LAN network using a fiber-optic connection (star or ring)
The E-LAN port is always a two-wire RS485 connection.
