PROFIBUS DP
Finally, the process data output (from the controller to the TOP Control Continuous) is entered.
PDI
: Process Data Input (continued)
(from the TOP
Control Continuous to the controller)
PDI. PV
and
PDI. SP
can only be selected if the process controller has been activated.
PDI.P1/P2/MTMP
can only be selected if the fluid flow controller option is active.
NOTE
In the same order as in the selection in the TOP
Control Continuous and only process data
(
PDI
) activated in the configuration menu may be entered.
The updating of the process data output only takes place in the MANUAL and
AUTOMATIC modes.
NOTE
Name Description Identifiers
