In ProTool (ProAgent) I want to select
an S7 Graph sequencer for diagnostics. The instance DB assigned
to the sequencer is not offered as a diagnostics-supporting unit
in ProTool under `Target system - ProAgent`.
The are two possible reasons why the S7-Graph
sequencer is not offered as a diagnostics-supporting unit in ProTool
under `Target system - ProAgent`.
- The S7-Graph sequencer is not set to support
- The OP is not linked to the controller.
Open the sequencer FB in your S7 configuration.
Via Tools - Settings - Compile
select how the FB is to be compiled. Select one of the two options.
With acknowledgment (SFC 17) or without acknowledgment (SFC 18).
Then the sequencer FB supports diagnostics.
In your ProTool configuration, open
Target system - Control Panel - Edit - Parameters
and link the OP to the communications partner via MPI or via PROFIBUS.
