Pulse counters

Some specific binary inputs (see the table in section "Binary inputs") of the REM 543
machine terminal can be programmed either as binary inputs or as pulse counters. This
programming is done via the parameter Input # mode (in this parameter as well as in
others mentioned below, # denotes the input number).
When an input operates as a binary input, no counting is done but the pulse counter
value remains at the present value.
When an input operates as a pulse counter, the positive input transitions (0 -> 1) of a fil-
tered input are counted and the counter value of Input # counter increases in the range
0... 2147483647. The frequency range of a binary input parameterized to operate as a
pulse counter is 0.....100 Hz.

The parameter Input # preset can be used to give a pulse counter a start value. The start
value is loaded into the counter by:
• writing the desired start value to the parameter Input # preset,
• writing the value 1 to the parameter Counter trigger. Then all the updated values of
the Input # preset parameters are copied to the corresponding Input # counter param-
eters.
Writing the value 2 to the Counter trigger parameter copies all the Input # preset values
to the corresponding Input # counter parameters, whereas writing the value 0 clears all
the counters.
Parameter Values
Input # preset 0..... 2147483647
Input # mode 1 = binary input
2 = counter
Counter trigger 0 = clear all counters
1 = load updated Input # preset
values
2 = load all Input # preset values
