on The connection is error with PROFIBUS Master device orPROFIBUS system configuration is not correct.off PROFIBUS system configuration is correct.It is normal operation.on Data exchange mode.It is normal operation.RUNoff GW-7553 module is not in data exchange mode.3. Establish connection with GW-7553Before establish the connection between DP-Master and GW-7553, usersshould obey the following steps first.1. First, users must load theelectronic device description file(GSD file) of the GW-7553 intothe DP-Master.2. And then set the parameters andconfigurations.3. Finally change your DP-masterfrom offline state to operatestate. The GW-7553 will beinitialized. If there is no erroroccurs, GW-7553 proceeds intodata exchange state. At themeantime, if there is any erroroccurs, GW-7553 will return towait for parameterization.4. Software configurationGSD filePlease copy the GSD file (IPDS0C0D.gsd) and the bitmap file (ICP_7553.bmp, GW_7553.bmp) from the CD of the GW-7553 module into the Profibusconfiguration tool.File->CopyGSD(Directory: --> CD:\profibus\gateway\gw-7553\gsd\) the example of how to load GSD fileHere, we use the hilscher CIF50-PB PROFIBUS communication interface toshow how to load GW-7553’s GSD file step by step.GW-7553 PROFIBUS/Modbus TCP Gateway Quick Start (Version 1.10, May/2012) PAGE:3
