tracks its input.
The following steps are required to set the AO block into cascade mode.
1. Set MODE_BLK: TARGET to OOS.
2. Set SHED_OPTS to NormalShed_NormalReturn.
3. Set CHANNEL to 1.
4. Set MODE_BLK: TARGET to Cas|Auto.
FVPTB Block: Set the transducer block mode to Auto.
Controlling the Valve:
If all the function blocks are set up as outlined above, the positioner should now tack the output of the
transmitter (the AI block). If not, verify that the blocks are set up as outlined above.
Saving the Configuration:
This configuration can be saved by the Configurator. This is recommended if the PC is going to be
disconnected or removed from the FF network. The Configurator is not able to reconstruct the graphical
wiring diagram, so reconstructing a pre-configured network is extremely difficult. By saving the configuration,
the graphical wiring diagram is saved. Saving is done upon exit from the Configurator software.
