Timer, counter T, C
(l)Timer, counter list
Use "Sheet form 7". The timer and counter are used jointly, and up to 127 points are possible.
Accordingly, discrimination between timer and counter must be made with T or C in the TIC
selection column of the list.
First assign the timers required by the control specifications. Next, assign the timers required at
the time
of
design of the control circuits.
When the timer setting time is the same, a timer can be used repeatedly, as long as the opera-
tion does not overlap. Accordingly, when the number of timer points is not sufficient, this
technique should be used by employing the same setting time as far as possible.
At the time of timer number assignment, also enter the setting time limit into the list. Time set-
ting is executed in units of 0.1 sec.
(2)Timer assignment
P - 2
(3)Counter assignment
Assign the counters required by the control specifications. In the same way as for timers,
repeated use with the same value is possible as long as the operations do not overlap. It is con-
venient to enter both count input and reset input into the list.
