6.9 Special parameters, input explicit messaging
Special parameters are parameters that might be used by the PLC, but bear no relation to the operation of the digital dosing pump.
7. Product simulation
The CIM module can be put in product simulation mode in which
case it generates life-like simulated values of all the EtherNet/IP
input data parameters.
It will thus be possible to connect an EtherNet/IP master to CIU
500 without this device being connected to a real pump in a real-
life system. In an office environment, it can then be verified that
communication works and data is being received and handled
correctly by the master application program, for example PLC
program, before the equipment is installed under real-life
conditions.
Product simulation mode is entered via the webserver. See
section Webserver configuration on page 29.
The below functional profiles can be selected from the webserver.
Only input parameters are simulated. The data read has dummy
values and no real product functionality is simulated.
309 MeasuredPressure
SINT16, 0xC3
0.1 bar 0 - 3276.7 bar
Measured absolute pressure. The
SetFlowControlEnable bit (parameter 10)
must be set for this value to be available.
Except for the atmospheric pressure, it
corresponds to the “Backpressure” reading
on the display.
310 PulseInputFrequency 1 Hz 0 - 32767 Hz
Frequency of pulse input. Can be an external
pulse input signal or pulses coming via the
TrigPulse (parameter 17) command.
311 RemainingDosingVolume
SINT32, 0xC4
0.001 ml 0 - 2147.5 l
Remaining volume to be dosed. Used in
“Batch” mode.
312 VolumeTotal 0.001 l 0 - 2147.5 m
3
Total volume dosed (non-resettable).
313 VolumeTripCounter 0.001 l 0 - 2147.5 m
3
Volume trip counter. Can be reset with
TrigResetVolumeCnt (parameter 18)
command.
314 NoOfPowerOns 1 0 - (2
31
-1)
The number of times the pump has been
powered on (non-resettable).
315 RunTime 1 min 0 - (2
31
-1) min
The amount of time the pump has been
dosing (non-resettable).
316 OperatingTime 1 min 0 - (2
31
-1) min
The amount of time the pump has been
powered on (non-resettable).
317 StrokeCounter 1 0 - (2
31
-1) Total number of strokes (non-resettable).
318 TimeToNextDosing 1 s 0 - (2
31
-1) s
Time to next dosing. Only available in
operating mode "Timer".
319 AnalogInput
SINT16, 0xC3
0.001 mA 0 - 20.000 mA
Analog input value. The value is used as
setpoint in operating mode "Analog".
320 AnalogOutput 0.001 mA 0 - 20.000 mA
Analog output value. The parameter to map
to the output is selected via the operating
panel. If controlled from bus is selected, the
analog output signal can be controlled from
SetAnalogOutput (parameter 34).
