Profibus DP an Introduction White Paper (Log in to view the file)Introduction to Profibus DP The following information describes the operation of Profibus DP as it relates to Acromag Series 900PB DP slave I/O modules. Acromag manufactures a line of I/O modules that support Profibus DP over RS485.How to Monitor Stator Temperatures with Remote Profibus I/O Application NoteMonitoring Stator Temperatures with Remote Profibus I/O Defining the Problem: A Power Plant has Hydroelectric Generators with 10 ohm copper 3 wire RTDs embedded in the stator motor windings. The RTDs are far away from a PLC in the control room. The long distance is picking up noise that is interfering with their measurements. System... -
