INPUT counters and sub-counters
All inputs can be active low or active high. They generate an alarm whenever
they have been pulled active for more than the programmed length of time
(from 2 to 32000 seconds ).
You can read anytime INPUTs status with the #GIO command.
Input 1 to 6 can be individually programmed to behave differently and count
the input active low pulses, up to 14 ms fast.
This means that you can connect them to a mechanical counter or to a coin
acceptor and count the pulses.
Every pulse will increment the Counter related to that input ( i.e. COUNTER 1
for Input 1) and also the SUB counter related to it.
The sub-counter will increment until it reaches a value equal to the
comparation value, as stored into the COMPARATOR VALUE available for each of the 1..6 INPUTS.
When that value is reached, the SUB-COUNTER returns to 0 and an ALARM
is sent with the text for that INPUT to the GSM number(s) indicated in the matrix, for that INPUT.
All COUNTERS, SUB-COUNTERS, COMPARATORS values can be programmed using commands #CNT, #CNP, #CCA.
Input mode can be set using the #IDT command.
When used as counters input work only in ACTIVE LOW mode. They count ONLY Low Going Pulses.
In TCS 3.5 produced after september 2003 there ia also a Time counter function.
Once the a specific input is programmed to behave as a time counter (see IPM command).
Time Counter: increments COUNTER and SUBCOUNTER every 10 minutes that input is
kept continuously at a LOW level. SUBCOUNTER is reset to 0 every transition from HIGH to LOW
of the related input.
