17-4 Memory Allocation
The memory allocation about analog conversion in the CIO area of PLC is shown as the following diagram.
The range of the CIO area is CIO 8 0 to CIO 8 9.
The details of allocated CIO channels are described in the following table.
Option board status area: A4 3 5 (initial value “0000H”)
Note The flag sets ON if Analog Option Board has already worked normally. Then A/D input data can be read and
D/A output data can be written.
Output off bit: A500.15
Note This bit will also affect other PLC output channels.
Option board error bit: A 3 15.1 3
