3.2.2.8 Explanation on special registers D9900~D9999
When an ELCM controller is connected to I/O modules, registers D9900~D9999 will be reserved
for storing values from those I/O modules. Use the MOV instruction in the controller program to
read/write values in D9900~D9999.
When an ELCM controller has ELCM-AN02NANN / ELCM-AN04NANN connected, these special
registers are assigned per the table below:
