XP248 multi-serial port and multi-protocol communication card connects the data of user intelligence system to DCS system through communication, and realizes the * * * sharing of data in DCS system through SCnet network.

On the panel of XP248, there are two redundant SCNET Ⅱ network ports, namely SCNET Ⅱ A and SCNET Ⅱ B: SCNET Ⅱ A: SCNET Ⅱ Communication Port A, which are connected with the A# network of redundant network SCNET Ⅱ.

Scnetⅱ b: the communication port b of scnet ⅱ is connected with the B# network of redundant network scnet ⅱ.

General knowledge of central control dcs in Zhejiang University

XP248 is configured for communication through SCC Control graphic programming software. SCControl software integrates communication setting function block, Modbus RTU function block, HostLink function block, etc.

XP248 can use numerical or logical operation function blocks provided by SCC control software to realize complex conversion of output data of intelligent module according to needs. (I/O function block and PID sc control algorithm function block in SCC are not supported.
