The whole block will now get address 32. This means that if address 32 is requested that all
variables will be returned.
Do the same with the hourly, daily log and possible other logs, giving them the address 701 etc.
Make sure that all doubles are replaced by unsigned longs as above.
As with any modbus, make sure that the byte order matches your computers.
From Local/ modbus log information, move the modbus log history index for the event (#3 in this
case) and modbus log history indexes from #1 and #2 to the right and give them addresses 7001
and following:

8 .5 .4 Define Modbus alarms
The last step is to define the alarms. The reason is because the Summit has far more alarms
than traditional machines and then defined in the Enron Modbus specification. Here only the fol-
lowing alarms can be distinguished:
• LoLo limit
• Lo limit
• Hi limit
• HiHi limit
• Rate of change limit
Therefore a remapping of alarms is needed.
For this purpose go to General/ Modbus Alarms. Here all variables, defined in the modbus are
listed. Select the ones that need to be alarmed and double click them to be included into the
Alarmed Id’s.
