Configure MODBUS Gateway parameters
Digi TransPort routers support conversion from MODBUS serial to MODBUS TCP.
Requirements for MODBUS support in TransPort devices
When converting from MODBUS serial to MODBUS TCP over a WAN link, it is necessary to have
intelligence in the router to minimize the effect of the higher latency.
Digi TransPort supports being a MODBUS server only. Clients, such as remote PCs, can send
overlapping requests. The router will create a queue of info requests and deal with them
appropriately, sending them out over the serial port and relaying the responses back.
Overlapping polls from multiple clients are supported.
Modbus Gateway configuration parameters
Modbus Gateway parameters are configured on the
Configuration > Network > Legacy Protocols > MODBUS Gateway page.
