To accommodate all the PVs that can be associated with a given
SMV 3000 transmitter, you must build an AI point for each PV up to a
maximum of four points (PVs) per transmitter. Each point built must have
the same name assigned for the STITAG parameter and be assigned to
contiguous slots. The IOP will calculate the number of PVs based on the
number of identical contiguous STITAG parameters and allocate the
appropriate number of logical slots in addition to the master slot.
The master slot represents the slot to which the transmitter is physically
connected and is identified as PV number 1. It is the lowest numbered slot
in a group of contiguous slots with identical STITAG names. The PV
numbers are assigned consecutively for the associated logical slots as 2, 3,
and 4. As shown in Figure A-4, a transmitter configured for 4 PVs and
connected to the terminals for slot 5 on the IOP will have PV numbers 1, 2,
3, and 4 assigned for PVs associated with physical (master) and logical
slots 5, 6, 7, and 8, respectively.
Since the master slot as well as all associated logical slots are built as
separate AI points, each slot/PV has its own configuration parameters and
functions like a separate transmitter database. This means you can modify
individual parameters for a given PV independent of other PVs. However,
changes in common parameters like STITAG will also affect the other PVs.
