GW-7557 is a PROFIBUS/HART gateway module that can be used to convert PROFIBUS and HART communication information. This module is a slave device in the PROFIBUS communication, and the communication address can be set from the internal DIP switch, supporting addresses between 0 and 126.
This guide provides a brief overview of the GW-7557 PROFIBUS/HART Gateway, showing how to install the module, connect it to a PROFIBUS DP master and HART devices, and set the module address using the DIP switch. It also explains the LED indicators that show power, error, and run status.
The document describes the required software steps, including loading the GSD file into the PROFIBUS configuration tool, configuring module parameters, and performing a communication test with HART devices. After configuration, a power reset is required for the settings to take effect. This manual is written in Chinese.
| PROFIBUS address range | 0‑126 |
|---|---|
| JP5 channel mapping | Channel 0 |
Open the module cover, locate the DIP switch, and set the desired address (0‑126) using the switch positions.
After completing the configuration steps, power‑reset the GW-7557 to make the settings take effect.
