Acromag strongly suggests the use of these tools for building and maintaining ProfiBus networks. Note that Profichip also offers a Profibus connector (PA003100) that includes 4 network diagnostic LED’s that may be helpful in trouble-shooting your network (see table below). -

In Configuration Mode, the module will automatically calibrate the channel’s zero value when FFH is detected. Then write 00H into the low-order byte to complete zero calibration. _______________________________________________________________________________________ Acromag, Inc.
