•
SLC 5/05, SLC 5/04, and SLC 5/03 controllers can respond to
PLC5 Typed Read or Write message types that use logical ASCII
addressing. Using this message type, the Logix can directly read
or write the status (S) file and float (F) file(s) of these SLC
controller versions (in addition to the N and B file types).
•
The maximum number of integer file elements that can be
transferred with any SLC 5/03, 5/04 or 5/05 controller using a
single Logix MSG instruction is 118.
•
The maximum number of integer file elements that can be
transferred with any MicroLogix 1100/1200/1500 controller using
a single Logix MSG instruction is 121.
•
The maximum number of integer file elements that can be
transferred with any MicroLogix 1000 controller using a single
Logix MSG instruction is 41.
