Emerson Exchange 365

The BFI block doesn't give a "true" first out indication, if multiple alarms were active on the same execution of the module all these alarms would be trapped so logic would be needed to find the first one found anyway (probably similar logic) and the ignore/suppress the others.
The CEM block has alot more functionality than what would probably be required, I believe the first out works the same as the BFI block and it would most likely also need some addition logic as well.
So because of the need of the additional logic and needing to review the first out trapped to find the very first alarm active again anyway, it was just all done with a CALC block.

Hi Gelo,

It is easily expandable up to 96 alarms. Emerson doesn't provide an example of expanding it beyond 16, so it will take a little thought and coding to get it there. If you look at the ALM_FLOOD_XX modules, you can see the difference between the 16 and 32 alarm versions. This will give you a clue on what to start thinking about.

When I say "easily expandable" I mean that the Faceplate and Detail displays are pre-built to handle 96 alarms. As you add the necessary parameters to the module, they will automatically appear on the displays.
