The PCs are equipped with analog controls that automatically transfer the set-
tings on the CPU Unit's adjustment switches to words in the CPU Unit's I/O me-
mory. This function is very useful when there are set values that need to be pre-
cisely adjusted during operation. These set values can be changed just by turn-
ing the adjustment switches on the CPU Unit.
The PCs have two analog adjustment controls that can be used for a wide range
of timer and counter analog settings. The following diagrams show the adjust-
ment controls. As these controls are turned, values from 0000 to 0200 (BCD) are
stored in the SR Area. Use a Phillips screwdriver to adjust the settings.
If the addresses for Slave 1 and Slave 3
are the same, the Master will not be able
20000
to read input from Slave 3.
If a communications error is generated,
the status of IR 00100 will be the same
as before the error and so the change in
20100
the status of the actual input will not be
detected.
