(b) Preset time is 8 to 262,136 ms.
Processing is done every 8 ms in this fixed timer.
The preset time is therefore integral times of 8 ms and the odds are
omitted.
For example, when set 38 ms, 38=8 4+6, the odd 6 is omitted, and
the preset time becomes 32 ms.
The range of the preset time is 8 to 262,136 ms.
For the PMC–SB7, preset time is 1 to 32,760,000 msec (about 546
minutes).
Time varies 0 to level 1 sweep interval from the setting time.
The varing time in this timer is caused only the error occurred when the
timer instruction performs operation process.
Error caused by sequence program processing time (time of 1 cycle of the
second level), etc. are not included.
