Description
When you buy an I-7188EX-MTCP controller, it already includes the default Modbus firmware installed into its Flash memory. The default firmware has the following features:
-
Converter single Modbus/TCP to multi Modbus/RTU
The I-7188EX-MTCP is a Modbus/TCP gateway. It can easily upgrade many Modbus/RTU devices to have Ethernet communication ability. -
Supports VxComm technique for each of the controllers COM ports
If your serial devices does not support Modbus/RTU, you can still access these devices by installing the VxComm driver on the host PC and assigning a COM port number to link to the remote COM port (of I-7188EX-MTCP). After that, serial clients can access these remote serial devices via standard RS-232 functions. -
Allows multi-client (or master) computer access simultaneously
-
Firmware is modifiable
The Modbus SDK is provided which allows users to develop their own custom Modbus firmware.
The following tools for windows computers are also provided:
-
Modbus Utility
- On-line configuration via Ethernet
- On-line help
- Automatically generate register mapping tables
- Configuration export/import
-
MBRTU
Modbus/RTU client (with source code in VB6) for diagnostics to Modbus/RTU slave devices. -
MBTCP
Modbus/TCP client (with source code in VB6) for diagnostics to Modbus/TCP slave devices.
