Interfaces Type Description
iiCycle_Error Int Specification of the cycles as delay of the warning and
fault oxWarning, oxError and oxErrorProfibus.
Through the delay short drop-outs in the PROFIBUS
®
system can be bridged.
The delay time is calculated as follows:
When using the function block in OB1:
Delay = measured cycle time * iiCycle_Error
When using the function block in OB35:
Delay = time wake alarm * iiCycle_Errror
This value uses the workaround Profibusbug.
If the pump is not at a standstill, or if it does not start up
on its own after a Profibus fault, adjust the value so that a
value of approx. 1s is achieved.
Example:
Call block of pump P1 every 50 ms, then the value 20
should be set.
oxRunning Bool 0 = pump is at standstill
1 = pump is running
oxWarning Bool 0 = No warning
1 = Warning active
oxError Bool 0 = no fault
1 = fault active
oxErrorProfibus Bool 0 = Profibus OK
1 = Profibus faulty
oyMode Byte 00 = Manual
01 = Batch
02 = Contact
03 = Analogue
orActualFrequency Real Actual stroke frequency in strokes/min
orActualDosingVolume Real For calibrated pump: Actual metering quantity in l or gal‐
lons
For uncalibrated pump: Value 0
