Configuration - Network > Legacy Protocols > MODBUS
Digi TransPort routers support conversion from MODBUS serial to MODBUS TCP.
When converting from MODBUS serial to MODBUS TCP over a WAN link it is necessary to
have intelligence in the gateway\router to minimise the effect of the higher latency.
Digi TransPort supports being a MODBUS server only. Clients (e.g. remote PCs) can send
overlapping requests and the Digi TransPort 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.
Enable MODBUS Gateway
Enables or disables MODBUS gateway instance.
Async Port
Configure the local serial port number (asynchronous port) for the MODBUS serial interface.
Async Mode
Configures the serial driver for RS232 or RS485 on supported hardware.
Duplex Mode
Sets the duplex mode to half or full. Full would be for 4-wire installations otherwise half is
required.
