Technical support / T100MD+ as tacho/pulsefrequency
« on: August 01, 2006, 07:32:32 PM »
I am trying to configure my T100MD+888 to take an input from a hall effect sensor providing a square wave output.
The first line of my program has the " first scan" bit and then a fuction box where " PMON 3" is written.
The second line has the "clock 0.05s" bit and then function box where "DM[1] = PULSEFREQUENCY (3)" is written
When I write to the PLC and test the DM[1] value is always at zero, i have a few different inputs ie dig in 3 pulsed straight to ground instead of using the sensor, but nothing works
I am pressuming I am not programming it correctly.
Can anyone suggest anything?
Thanks

Technical support / ANALOG OUTPUTS RISING TO 4096 N/C
« on: July 30, 2006, 11:45:27 PM »
When I activate the ADC command and the 0-5v sensors are not connected the value slowly rises to 4096, i e 5 volts. If a wire to a sensor should break the same will occur? As these sensors can trigger a shutdown alarm when a preset value is met, if a wire breaks then the value will rise and meet the setpoint and cause a shutdown.
How can I avoid this??
