Size Limitations
AM2020/AFP1010 Control-By-Event
Examples:
1.
The following Control-By-Event takes up 13 bytes in memory:
2.
The following CBE takes up 11 bytes in memory:
Due to the 14-byte size limitation, it may be necessary to use more than one Equation or List to accomplish a desired result. Through the use
of reverse activating zones, an equation which normally would contain too many bytes can be broken up into several smaller equations.
In the example below, a control module is to be activated by any one of 14 software zones:
