Profibus DP (Decentralized Peripherals) 
This protocol is typically used to operate sensors and actuators via a centralized controller within industrial-
ized production topologies. Data rates up to 12 Mbit/s on twisted pair cables and/or fiber optics are possible. 
Profibus versions DP-VO and DP-V1 are supported on Watlow devices that use Profibus DP. 
DP-V0 provides basic DP functionality, including cyclic data exchange, station, module and channel specific 
diagnostics and four different interrupt types for diagnostics and process interrupts. To use DP-V0, you'll 
first configure and then register the General Station Description (GSD) file using our 
Profibus GSD Edi-
tor.
 With the GSD Editor, you can configure up to 244 I/O bytes that can be read or written to from Zone 1 
through 16. 
DP-V1 includes acyclic data communication for parameter assignment, operation, visualization and interrupt 
control of intelligent field devices, in conjunction with cyclic user data communication.
