Instruction Manual

III-20.2 F_Inp (frequency/counter input)
The frequency/counter input plugs into the modular options card C.The F_INP is used for configuration and parameter
setting of input F_INP. Input calculation is fixed to once per time slot.
Digital inputs:
reset a
1 = the value for Inp_a is reset to 0.
stop a
1 = the instantaneous value for Inp_a remains unchanged.
reset b
1 = the value for Inp_b is reset to 0.
stop b
1 = the instantaneous value for Inp_b remains unchanged.
Digital outputs:
slotid
0 = correct module fitted
1 = wrong module fitted
fail
1 = inserted module is detected, but no communication to the module.
z_a
signal status of HW input a
z_b
signal status of HW input b
ov_a
1 = frequency at HW input a exceeds the maximum permissible 20kHz
ov_b
1 = frequency at HW input b exceeds the maximum permissible 20kHz
Analog outputs
Inp_a
output value for channel a
Inp_b
output value for channel b
