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.
Features:
- HART (4Ch) to PROFIBUS DP-V0 Gateway
- max Baudrate: 12 Mbps
- Automatic transmission rate setting
- Up to 15 HART modules
- GSD File for easy integration in the PROFIBUS Master
- Free utility to configuration and test of GW-7557
- Max in/out message size: 240 Bytes
