6. Function blocks
6.1 Manufacturer function blocks
6.1.2.3 CH - High-speed counter
General
easyE4 base devices provide 4 high-speed counters
CH01…CH 04.
The high-speed up and down counters are internally hard-
wired with the digital inputs I01...I04 and operate inde-
pendently of the cycle time.
Operating principle
The contacts will switch according to the actual value. The appropriate function block
outputs switch according to the actual value determined. The counter relays enable a
preset start value to be defined at the SV input.
Only square wave signals are permissible.
The mark-to-space ratio is 1:1.
The counter wiring must observe the following digital input assignment:
l
I01 Counter input for the CH01 counter relay
l
I02 counter input for CH02 counter relay
l
I03 counter input for CH03 counter relay
l
I04 counter input for CH04 counter relay
NOTICE
Avoid unforeseeable switching states.
Switch C, CF, CH, CI function blocks only at one single point in the pro-
gram.
Otherwise, previous counts will be overwritten.
