Problem PLC profibus with Siemens DP/PA link

[eddyt]

Hi, any 1 have experince with profibus with siemens DP/PA Link (IM153 + FDC157) ? Actually the FDC157 (DP/PA coupler) only work at 45.45kbs, without the IM153, I had successfully communicate with PA device using OMRON plc. The problem occur when i want to set thee DP enviroment to 93.75kbs. And i knew that an adapter should solve the problem (IM153). When I applied the IM153 + FDC157, the PLC can not talk to the PA device at all. I'm already generate the PA gsd file using gsd tool given by siemens website. What should i do now ? or is there any other things missing ? DP/PA link need additional configuration ? Sorry for my bad english. Any help will appreciate. Thank you.
