almost a mirror image of what we're having! ours is plc-5, sst card, sew vfd, and siemens powerhouse. different causes each time. check that both ends of the loop have terminating resistors "on" and cables on A1 and B1, both ends. gsd or gst files are loaded for each component, strip the pfb cable 1/4 inch longer...if you use the cable stripper as "gauge". this sounds silly but it worked for me...power down and power up! good luck...
