PI Point Configuration28
Float32
Float64However, the Interface cannot store a negative number in an Int point type. Thus, to store a
negative value into a PI point, the user should configure a Float-type point instead.
For more information on these point types, seethe PI Server manual.
Location1Location1 is the CIU number or the interface ID number. This number does not correspond to any parameter on the Net90/Infi90 side, but it is often set equal to the node number of the CIU for easy identification. This number
must match the value of the –ciu#=parameter specified in the command file.
Location2Location2 is the Bailey PCU (i.e. node) portion of the Bailey address for inputs.
For inputs with a CIU04, Location is 256 times the loop (i.e. ring) number plus the PCU number. For example, a loop number of 4 and PCU number of 29 indicates that a
Location of For output points, Location is the CIU index. The user must assign a unique CIU index for each output point. This index is used as the block number when configuring Bailey modules to read the output (the CIU module number would be 2 and PCU would be the
CIU's node address).
For example,
a PI tag named CR:T121with index number 49 for the PI-connected CIU whose node address is 25 could be read from another node on Plant Loop with an analog input block (FC26) by:
