Features of default Modbus firmware
|
|
When you buy an I-7188E2 -MTCP controller, it already has the default Modbus firmware installed in Flash memory. The default firmware has the follows features:
-
Supports VxComm technique for every COM port of controllers?
If serial devices don't support Modbus/RTU, you can still access these devices. But need to install VxComm driver on host PCs and assign a COM port number to link to the remote COM port (of I-7188E2 -MTCP). After that, serial clients can access these remote serial devices via standard RS-232 functions.
-
-
Firmware modifiable?
We provide the Modbus SDK allowing users to develop their custom Modbus firmware.
