Dear all,
I am currently working on a DeltaV project. I have multiple SFCs that are part of a big sequence . I want to put them online together but the control studio allows to put only 4 CMs online.
Is there a way to put multiple CM online. I can't test my control philosophy without it.
Thanks & Regards

Multiple professional workstations. 4 sessions per workstation. But obviously requiring an SI dongle or appropriate licensing.
If you only have a single Proplus, that's a bit tricky.
another option would be to use multiple "watchit" windows to pull up parameters from other sfc modules, or put a DeltaV graphic together to pull important values together.
I've never really struggled to debug a control strategy even with the limit of four control studios sessions, your strategy must be pretty complex.
Good luck,
Neil.

Thanks a lot Neil. I have multiple vessels, each having its own sequence (although these are quite similar) and a big sequence governing them all . I don't have a batch license due to which i can't put a generic operation to them all and make a recipe therefore i have to work with coping and testing each SFCs one by one.I just want to view the execution order of the SFCs. Making an operate view for testing purpose is a good idea . I will go with that for now. Can you suggest anything else to increase the comfort of my testing?
Thanks a lot :)

In reply to M_ASIM_B:
Sounds like a novel approach to bypassing batch licensing which isn't always the cheapest option considering the additional engineering effort to do that.
Anyway....
Try googling "Control Studio is limited to 4 sessions by default" and "MaxMdeApp", you may get lucky., a presentation from User exchange 2012. Something I've never tried and it could make your system unstable and probably not supported by Emerson. If you are not on a live DeltaV system i.e. just testing on a development system it could help you.
I would totally advise against doing this on a live system.
In either case investigate fully before hand and use at your own risk, I give no warranty.
