(3) Program conditions
The CPU module mounted on the remote master station reads the values
counted under the following condition by using the QD62 in a program.
Preset value
Coincidence output point No. 1
Ring counter minimum value
Ring counter maximum value
Sampling time setting
Periodic pulse time setting

2 Set only when the sampling counter function is used
3 Set only when the periodic pulse counter function is used
POINT
Programs that were used in earlier products such as A1SD62(E/D/D-S1) cannot be
used because the I/O signals and the buffer memory configuration of these
products differ from those of QD62(E/D). The conventional dedicated instructions
cannot be used.
