features and benefits
The GW-7557 Gateway is specially designed for the slave device of PROFIBUS DP protocol.
It allows the PROFIBUS master to access the HART slave devices.
These HART slave devices may be a transmitter, an actuator, a current output device and so forth.
In addition, we also provide the utility software for users to configure the GW-7557.
By using this module, users can put their HART slave devices into PROFIBUS network very easily.
