III-6.5 DELA2 ( delay time (No. 54) )
The function provides calculation y t x t Td 1 1 ( ) ( )
= -
Input variable x1 is output at y1 with delay by time Td. The accuracy Td is dependent of the time group ( sampling in -
terval ts) , to which the function is assigned.
Example:
Td = 0,7s with assignment to time group 100ms means Td = 0,7s
to time group 200ms means Td = 0,8s
to time group 400ms means Td = 0,8s
to time group 800ms means Td = 0,8s
The possible delay time is dependent of the configured time slot (sampling interval ts).
Td max = 25,5s with ts = 100ms
Td max = 51,0s with ts = 200ms
Td max = 102,0s with ts = 400ms
Td max = 204,0s with ts = 800ms
Inputs/outputs
Digital input
preset
= 1 The preset value is taken to the output
reset = 1 Output y1 is set to zero
With several simultaneous control commands:
reset
= 1 has priority over preset and stop
preset = 1 priority over stop
Analog input
x1
Input variable to be delayed
Preset Value output with delay by preset=1
Analog output
y1
Delayed output variable
