■ Mode setting
Write the desired mode No. into the first data memory.
Mode for pulse measurement
Mode for DM measurement
Write the desired mode No. into the specified data memory.
Example
Write "#0006" to obtain the average of the contents of DM0006.
Note 1: When the mode No. is set to 10000 through 11999, values are fetched at
the scan only when the PLS input relay is ON.
Note 2: When the average of a data memory is calculated, values "32768" to
"65535" are converted into corresponding compliment numbers (-32767 to -1) .
Note 3: Some data memories after DM1000 are assigned to special functions. Be
careful when specifying data memory for the ITVL instruction.
➮ Refer to "1.3.10 Data Memories" (p. 3-19) for data memory assignments.
