5.6 CONFIGURING PLC CONTROLLER TAGS
After you have configured the BIS M-
626’s Node via the
OnDemand Configuration Page ,
open your PLC program (i.e. RSLogix 5000) and, if you have not already done so, define two
Controller Tags (a Write Tag and a Read Tag ).
Controller Tag Naming
Controller Tags need to be assigned a name and size. Be sure to use the same Write Tag
Name and Read Tag Name that you specified in the OnDemand Node Configuration (i.e.,
EMS_WRITE1 and EMS_READ1).
Controller Tag Size
Due to handshaking overhead, Controller Tags must have the size capacity to store an
integer array equal to your previously specified Write/Read Size + three words .
So for example, if the Read Size you specified earlier was 100 words, the corresponding
Read Tag in the PLC must be able to store an array of 103 integers.

The Write Tag holds messages and response data generated by the BIS M-626 that
is bound for the host or PLC.

The Read Tag holds RFID commands and instructions intended for the BIS M-626.
