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.
This protocol is available in three functionally graded version; 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, module and channel
specific diagnostics and four different interrupt types for diagnostics and process interrupts.
Cyclic Data refers to input/output data that is pre-configured to pass from the Profibus-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 mes-
sage.
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 al-
ternative, point your browser to: http://www.watlow.com/products/controllers/software.cfm and navigate to
the bottom of the page and click on "Software and Demos" to download the software.
Using the GSD Editor a user can configure up to a maximum of 135 different parameters that can be read
or written to from Zone 1 through 16. DP-V1 - contains enhancements geared towards process automation, in
particular acyclic data communication for parameter assignment, operation, visualization and interrupt con-
trol of intelligent field 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 pri-
ority then cyclic messages. This type of messaging is typically used for the purpose of configuration or per-
forming some sort of a diagnostic function.
