Examples
By using the events, rules can be made for the use of the M-Logic.
Virtual Events
Virtual events are used to expand the number of events in a logic sequence.
The following shows how the output of Logic 1 is used to continue the sequence in
Logic 2.
The Logic 1 output is set to Virtual Event 1. The Event A in Logic 2 is Virtual Event 1.
This gives a total of five events that can be used in this logic sequence (A + B + C in
Logic 1 and B + C in Logic 2).
Set/Reset Function
If you use a single binary input for, for example, selection of AUTO/MANUAL, you need
a SET/RESET function, since two binary inputs are normally required for this.
In the following example, binary input no. 10 is used to switch between AUTO (input
ON) and MANUAL (input OFF).
First line
If input 10 = ON and AUTO = OFF (NOT Auto operation mode), then set AUTO mode
command.
Second line
If input 10 = OFF and MANUAL = OFF (NOT Manual operation), then set MANUAL mode
command.
In M-Logic, it looks like this:
