Program Control Instructions
Chapter 7
7Ć2
To override a group of output devices, you must use two MCR (Figure 7.1) or
ZCL (Figure 7.2) instructions: one each to begin the zone and one each to end
the zone. The start fence is always programmed with a set of input conditions.
The end fence must be programmed unconditionally.
