Configure a MODBUS gateway

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.
