Controlling the MC Unit from the CPU Unit Section 5-2
5-2-3 Automatic Mode
The MC program is executed in Automatic Mode. Use the following procedure
to operate in Automatic Mode.
The example provided here is for task 1.
1,2,3... 1. Set the MC Unit to Automatic Mode by turning ON bit 01 of word n+3.
2. Set the program number of the program to be executed. (Word n+2)
3. Turn ON the Program Number Read Bit (bit 07 of word n+3) so that the pro-
gram number set in word n+2 will be read by the MC Unit.
4. Turn ON the Cycle Start Bit (bit 02 of word n+3) so that the program corre-
sponding to the program number set in word n+2 will be executed.
The corresponding bits for tasks 2 to 4 are shown in the following table.
Ladder Programming Example for Executing an MC Program
The following program is an example of the kind of ladder program used to
execute an MC program. This program is the minimum required to execute the
MC program. Add the program elements needed for your actual application.
Use work bits for inputs R1, R2, R3, and R4.
In the sample program, program number P001 is executed in task 1. Change
the task and program number if necessary.
