Entry:
0 = off, verification totalizer disabled
1 = do not total, verification totalizer is enabled, but main totalizers* are disabled
2 = add total, verification totalizer is enabled as well as main totalizers*
*main totalizers consist of internal totalizers 1 and 2, and external totalizers 1 and 2.
P638 External Totalizer Resolution
Note:
count at 100% of design rate, the next possible resolution is automatically
entered.
This parameter sets the resolution of the selected external totalizer.
Totalizers are:
P638-01, external totalizer 1 (T1), terminals 35/36
P638-02, external totalizer 2 (T2), terminals 38/39
Entry:
1 = 0.001 (one thousandth)
2 = 0.01 (one hundredth)
3 = 0.1 (one tenth)
f
4 = 1 (unit)
5 = 10 (x ten)
6 = 100 (x hundred)
7 = 1000 (x thousand)
P643 External Contact Closure
Sets the duration of the contact closure, in ms, for the external totalizer selected,
totalizers 1 and 2 (P643-01 or -02). (
Permissible values are in 10 ms increments from 0. The value is automatically calculated
upon entry of P1 (design rate) and P638 (totalizer 1 resolution, external) so that the
duration of contact closure allows the transistor switch response to track the total, up to
150% of the design rate. The value can be changed to suit specific contact closure
requirements, such as in the case of programmable logic controllers.
Note:
rate, the next possible duration is automatically entered.
P647 Totalizer Display
Selects the totalizer combination to be displayed, either manually through the scroll
display key or automatically by control of the display mode (P081).
