DVP-ES2/EX2/SS2/SA2/SX2/SE&TP Operation Manual - Programming Exception: If K is used with an X/Y/M/S device, a nibble device, a byte device, a word device, or a double word device will be formed. Example: K1Y10 represents a device composed of 4 bits, K2Y10 represents a device composed of 8 bits, K3Y10 represents a device composed of 12 bit, and K4Y10 represents a device composed of 16 bits. K1M100 represents a device composed of 4 bits, K2M100 represents a device composed of 8 bits, K3M100 represents a device composed of 12 bit, and K4M100 represents a device composed of 16 bits. Constant (H): A hexadecimal number in a PLC is generally preceded by H.
For example, the hexadecimal number H100 represents the decimal number 256. Reference Table: 2.8 M 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.
