wiring for timer0 in mode2
Posted 22 August 2011 - 12:03 PM
we need a little help, because we are unsure about wiring the UE9-timer-FIO for our reflection-sensor in proper style. Sensor uses an open-collector pnp output, that is output +UB (here for us +24V DC, possible range are +10...+36V DC) or open. This +24V power supply is generated by an external unit.
We believe to know, in I/O-line the Rseries of 22k is necessary. But testing failed. Maybe there is a problem with the correct voltage-level for low-signal?
A test with +UB=10V and UNI10DIV-extension was successfully. The timer value on T0V displays a number of clock cycles if pulses are activated (rising edges).
The aim is now an uniform supply voltage of 24V DC for all sensors we have. Is there a simple possibility for wiring the pnp-output?
Thanks a lot and excused the poor english.

Another option would be to use Modbus rather than the Profilab drivers:
