ProMinent gamma/l - Diaphragm Replacement

Interfaces Type Description
irSetpoint_0_100 Real Entry of the setpoint of the metering pump in %.
The formula of the calculation is:
Set frequency = MaxFrequency * irSetpoint / 100
Through the real number the speed on the stroke can be
precisely selected, because the entry of 49.99%, for
example, is possible.
Likewise a direct connection of the integrated S7 con‐
troller is possible. For this the output parameter LMN
must be connected on this input.
idStrokesInBatch DInt 0-99999 can be set for batch mode. At a positive flank on
the input ixStartBatch_Or_Contact, this number of strokes
will be executed.
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
oiStrokeLength Int 0 – 100 = 0-100% set stroke length on the metering pump
odStrokeNumber DInt Current number in the stroke counter in the metering
pump
orQuantity Real Current quantity in the quantity counter of the metering
pump
orVolumePerStroke Real Output volume per metering stroke (only for calibrated
metering pump)
