PRESET_CH1 INPUT DINT I, Q, M, D, L Channel 1:
Measurement period
DONE OUTPUT BOOL I, Q, M, D, L Ready signal
(TRUE = OK)
ERROR OUTPUT WORD I, Q, M, D, L return value
(0 = OK)
FM_PRESET_PERIOD_CH0 OUTPUT DWORD I, Q, M, D, L Setpoint value for frequency
measurement module output
address:
+0
FM_PRESET_PERIOD_CH1 OUTPUT DWORD I, Q, M, D, L Setpoint value for frequency
measurement module output
address:
+4
FM_CONTROL_CH0 OUTPUT WORD I, Q, M, D, L Setpoint value for frequency
measurement module output
address:
+8
FM_CONTROL_CH1 OUTPUT WORD I, Q, M, D, L Setpoint value for frequency
measurement module output
address:
+10
With setting ENABLE_FM the corresponding CONTROL is generated and issued via
FM_CONTROL_CHx. The measurement of both channels is started as soon as the con-
tent of FM_CONTROL_CHx was consistent transferred by the bus system to the fre-
quency measurement module. The measurement of both channels is stopped by reset-
ting ENABLE_FM, after FM_CONTROL_CHx was consistent transferred to the frequency
measurement module.
Only as long as the frequency meters are started, evaluated values can
be retrieved from the module. Otherwise you get the error message that
the channels are disabled.
Enter here the measurement period in µs for the corresponding channel.
Range of values: 1µs ... 8 388 607µs
Ready signal of the function
n TRUE: Function was finished without error.
n FALSE: Function is not active respectively there is an error.
This parameter contains the measuring period for channel 0 respectively channel 1. The
content is to be consistent connected with address +0 respectively +4 of the output area
of the frequency measurement module, via the according bus system.
