Memory Allocation
Section 10-4
10-4 Memory Allocation
10-4-1 CIO Area Allocation
The memory allocation about analog conversion in the CIO area of PLC is
shown as the following diagram.
The beginning CIO channel is shown in the following table.
CP1L-EL/EM series PLC
The details of allocated CIO channels are described in the following table.
10-4-2 Auxiliary Area Allocation
Analog Option Unit Status
Area
Option board status area: A435 (initial value “0000H”)
Note
A435.14 or A435.15 sets on if analog option board already worked normally.
Then user can read A/D input data and write D/A output data.
Output off bit: AR500.15
Note
This bit will also affect other PLC output channels. Please refer to Appendix D
Auxiliary Area Allocations by Address for more information.
