3.2.3.8 Explanation on special registers D9900~D9999
When the ELCM controller is connected to special I/O modules, registers D9900~D9999 are
reserved for storing values from these modules. Use the MOV instruction to rea/write to
D9900~D9999.
When the ELCM controller is connected to an ELCM-AN06AANN, the configuration of special
registers follows:

1. D9900~D9999 are average input values for CH1 ~ CH6 and the sampling range is
K1~K100. When the number of samples is set to K1, the values displayed in
D9900~D9999 are present values. Use: 1. ELCM_AIO Configuration Function in
ELCSoft or 2. FROM/TO instructions (CR#8~CR#11) to set the number of samples to
K1.
