The PLC-5 controller supports logical ASCII addressing so you do not have to

map a compatibility file for MSG instructions initiated by a PLC-5 controller.

Place the DriveLogix tag name in double quotes (“).

Example 3: Producing and consuming tags

You can produce and consume tags with any Logix controller the same as you

do with a DriveLogix controller. All Logix controllers follow the same

requirements for producing and consuming tags. See Example 2 above.

Typed Write SINT or INT tag any integer element (such as B3:0,

T4:0.ACC, C5:0.ACC, N7:0, etc.)

REAL tag any floating point element (such as F8:0,

PD10:0.SP, etc.)

R6:0, N7:0, F8:0, etc.)
