Modbus Gateway

Modbus gateway can realize Modbus TCP protocol converting to Modbus RTU, ZLAN Modbus gateway meanwhile has normal serial device server function.
ZLAN Modbus gateway has normal multi-host and storage type. The normal type includes ZLAN543, ZLAN5142, ZLAN5142-3, storage type includes ZLAN5143B, ZLAN5143BI, ZLAN43I, ZLAN7144 and so on. All the normal Modbus TCP query need to convert to serial data, after serial returning can return result to host, thus the reaction time is slower in usually 30~50ms. The storage Modbus gateway can automatically record data needed by Modbus host, it actively check RTU devices every time, updating its own cached data. When host need data just returned from the cache, query time is about 1ms, this greatly accelerates processing power of host.
