GW-7552 ~ NEW ~ 
PROFIBUS/Modbus Gateway |
|
|
|
|
|
|
|
| |
|
|
| |
The GW-7552 Gateway is specially designed for the slave device of PROFIBUS DP protocol. It allows the PROFIBUS master to access the Modbus devices. These Modbus devices may be a PLC, a sensor, ICPDAS M-7000 series modules and so forth. In addition, we also provide the utility software for users to configure the GW-7552. By using this module, users can put their Modbus devices into PROFIBUS network very easily.
