Example MSG Control Blocks
Figure 2.5 Example of a PLC-5 read MSG to Another PLC-5
(or SLC 5/03, 5/04, 5/05, MicroLogix 1100/1200/1500, or Logix) processor
This MSG example tells this (master) PLC-5 to read the information
from PLC-5 (slave) station 13

’s, location N7:0 and place the
information in file N19:0 (master).
