Description
The GW-7557 Gateway acts as a slave device using the PROFIBUS DP protocol. It allows a 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. Utility software is included to aid in configuration of the GW-7557 so that HART slave devices can be easily added into a PROFIBUS network.
