Profibus DP - (Decentralized Peripherals)
This protocol is typically used to operate sensors and actuators via a centralized controller
within industrialized production topologies. Data rates up to 12 Mbit/s on twisted pair cables
and/or ber optics are possible. This protocol is available in three functionally graded ver-
sion; DP-V0, DP-V1 and DP-V2. It should be noted that Watlow products utilizing this protocol
support DP-V0 and DP-V1 only.
DP-V0 - provides the basic functionality of DP, including cyclic data exchange, station, mod-
ule and channel specic diagnostics and four different interrupt types for diagnos-
tics and process interrupts.
Cyclic Data refers to input/output data that is pre-congured to pass from the Probus-DP
Class 1 Master and the Slave at a known rate. Cyclic data is expected on both the sender and
the receiver end of the message.
Note:
To use DP-V0 (cyclic data transfer) first configure and then register the General Station
Description (GSD) file. Watlow provides a software tool allowing for total customization of
the data to be read and or written to. Acquire this software tool (Profibus GSD Editor) via
the CD that shipped with the product or, as an alternative, point your browser to: http://
www.watlow.com/en/resources-and-support/Technical-Library/Software-and-Demos and
type "gsd" into the search field.
Using the GSD Editor a user can congure up to a maximum of 244 I/O bytes that can be read
or written to from Zone 1 through 16. DP-V1 - contains enhancements geared towards pro-
cess automation, in particular acyclic data communication for parameter assignment, opera-
tion, visualization and interrupt control of intelligent eld devices, in conjunction with cyclic
user data communication.
Acyclic Data is a message that can be sent and or received at any time where they typically
have a lower priority then cyclic messages. This type of messaging is typically used for the
purpose of conguration or performing some sort of a diagnostic function.
