ifm function elements for the device CR0403
Description
TRUE: execute this function element
FALSE: unit is not executed
> initiated processes continue in the background
> FB outputs are not updated
(MODE = 14 / 19 / 20)
Number of the fast input channel (0...3)
0...3 for the input IN0...IN3
(MODE = 25)
Number of the fast input A channel (0 / 2)
0 / 2 for the inputs IN0 / IN2
B channel = A channel + 1
Operating mode of the function block:
0 = 0x00 = no measurement
14 = 0x0E = frequency measurement
19 = 0x13 = interval measurement
20 = 0x14 = invertal and ratio measurement
25 = 0x19 = phase shift of two input signals
Number of periods to be averaged (1...4)
• if MODE = 14 / 19 / 20  average arithmetically
• if MODE = 25  average geometrically
• if PERIODS = 1  no averaging
(only relevant if MODE = 14)
time for counting the edges in [ms]
permissible values = 1...2 000
Description
period duration of the input signal in [µs]
frequency of the input signal in [Hz]
time elapsed since the last positive edge
mark-to-space ratio of the input signal in [‰]
feedback of the function block
