Setting the DIL switches
Note
On switch S1, the On position is on the left; on switches S2 and
S3, however, it is on the right (see Figure 6-10).
Coordination section
(number of CPUs)
You set the number of CPUs present in the PLC with the 3 DIL

The factory setting is "Number of CPUs = 2" (see below).
