2.8M Relay

The types and functions of special auxiliary relays (special M) are listed in the table below. Care should be taken that some devices of the same No. may bear different meanings in different series MPUs. Special M and special D marked with “*” will be further illustrated in 2.13. Columns marked with “R” refers to “read only”, “R/W” refers to “read and write”, “-“ refers to the status remains unchanged and “#” refers to that system will set it up according to the status of the PLC.
