Overall Format
The overall format for the communication zone of program is shown in
Figure 5.1. This figure shows each type of rung that can be entered in this
zone.
The actual communication zone rungs for any station processor may vary
significantly from those shown in Figure 5.1. The length of this program
area is a function of the number of remote stations processors with which
the local station processor communicates and the number of transmissions
of data with these remote stations.
