%M

22 (0016)

Discrete momentary internal memory (byte mode)

(Word 9) Local PLC - Memory Starting Address: Word 9 determines the starting address in the local PLC in which the response is to be written. The value entered is the offset (0-based) from the beginning of PLC memory for the memory type and mode specified in Word 8. This offset will be either in bits, bytes, or words depending on the mode specified (for example, if Word 8=16 and Word 9=2, the starting address will be %I9). Valid ranges of values depend on the PLC’s memory ranges.

(Word 10) Response Memory Size: Words 10 specifies the size of the memory block for the response. The Response Memory Size is 2 words. If the Response Memory Size (word 10 in the Clear Counters command block) is set greater than 2, the COMMREQ will succeed. The unneeded memory locations are not written.
