Continuous operation of equipment phases
With SIMATIC BATCH it is possible to
set different parameters for an equipment phase within a recipe without having to deactivate
the equipment phase and reactivate it again afterwards. Concurrencies, such as agitating,
temperature adjustment, pressure are also maintained beyond recipe operations. This means
for example that at the end of an ROP an agitator is not switched off, and at the beginning of
the subsequent ROP, it does not need to be switched on again.
Flowchart
Below, you can see the flow chart of a non-self-terminating equipment phase set to continuous
operation:
During the changeover, the equipment phase remains in the "READY TO COMPLETE" status.
Instead of terminating the equipment phase, the first recipe phase simply sets the
CONTINUOUS ID via the ICONT input in addition to the basic status. The setpoints/actual
values are read prior to this. The sequence logic handles "CONTINUOUS" and "READY TO
COMPLETE" in the same way as "COMPLETED", in other words the recipe continues.
Because the CONTINUOUS ID is set, the second recipe phase can occupy the equipment
phase although its status is not IDLE. Once it is occupied, the CONTINUOUS ID is reset. To
allow the second recipe phase to start the equipment phase, it is possible to START from
"READY TO COMPLETE" in the status transition diagram.
