Naming Tags
Use a convention when naming tags and consistently follow it. The
following convention is used internally at Allen-Bradley:
Prefix - identifies the machine section in multi section programs
Function - describes the function or signal
Suffix - identifies the units of the signal or control status
Prefix examples:
Sct1 = Section 1
Fan2 = Fan 2
RewA = Rewind A
Function examples:
SpdRef = Speed Reference
FaultState = Status of a fault
Suffix examples:
Rpm = Rotations per Minute
Ok = status OK
Off = contact Off
Full tag examples:
Sct2_SpdRef_Fpm = Speed Reference, in feet per minute, on Section 2
Fan5_FaultState_OK = Status of fault, where 1 = OK, on Fan 5
TIP: Add descriptions for each tag when creating the tag
