L1020 on a1sh cpu

[rfr23]

Hello, I'm trying to understand a plc programm on a mitsubishi as1h cpu. It put a value on K1L1020 ( [ MOV R36 K1L1020 ] ) And then it use the ladder contact L1020. I cannot find anything in the manual, does someone could tell me more about it ? thanks

It means that the value ot Fileregister 36 (R36) will be moved to bits L1020 - L1023 K1L1020 => L1020 -L1023 K2L1020 => L1020 -L1027 ... . For instance if the value of R36 is 3 (Decimal 3 = Bin 0011) then L1023 and L1022 are 0 L1021 and L1020 are 1

In Mitsubishi's PLC, "K1L1020" means binding four bit devices(L1020 to L1023) to a word device. So, "MOV R36 K1L1020" means moving bit 0 of word device "R36" to "L1020" ; bit 1 to "L1021"..........
