By turning triggers X0 and X1 ON or OFF, the mode for
the output transition when the elapsed value becomes
equal to the target value is specified.
The software reset (elapsed value is reset) operates when
trigger X2 turns ON.
The external reset control is disabled when trigger X3 turns
ON.
The target = elapsed output control is disabled when
trigger X4 turns ON.
The target value for channel 0 and the mode for the output
transition are updated when trigger X5 turns ON.
The number system is binary.
When trigger X7 turns ON,
- Writing target value 0
Transfer the contents of DT0 and DT1 to DT9104 and
DT9105 for target value area 0.
- Writing target value 1
Transfer the contents of DT2 and DT3 to DT9106 and
DT9107 for target value area 1.
Since R9010 is always ON,
- Data for controlling the high-speed counter board is
updated every scan.
- The control status of the high-speed counter board stored
in DT9121 is monitored by word internal relay WR1.
- The elapsed value of board channel 0 stored in DT9108
and DT9109 is monitored by DT4 and DT5.
The elapsed value of channel 0 stored in DT9108 is
changed to the contents of DT6 and DT7 when trigger
X8 turns ON.
