Buffer memory, which is a memory in AD module, stores digital signals converted by AD module and also records set values in currently operating module. AD conversion values which is stored in buffer memory 0 ~ 1 are stored into CPU memory to be used for program using FROM command.

R/W indicates whether or not reading / writing is available from PLC.
