[V130 with Cell & GPS]

Thanks DanT, allot of testing in my future I think.

[V130 with Cell & GPS]

We  sell systems that are installed on trucks for fueling (12v or 24v).  At the end of each transaction the customer wants a text message of fuel dispensed, date, time, GPS location, etc.  Any suggestions on Modem kit, GPS unit, or anything else would be appreciated.

DanT,

Thanks for the quick reply, much appreciated.

[V130 expanstion]

We currently have V130's that are 12vdc.  I want to measure temperature and one more analog input.  Which expansion, and adapter modules would be best suited.

Thanks in advance for the help.

[Shielding/Screening]

Shielding is the common term.  Screening is not used that often.  Shielding pertains to both cables and enclosures.  Grounding the shield at one end is ok if your only going  to see low field levels (high field levels both ends).  The shield termination should be as short as possible.  At high frequencies a longer length  termination will be an open.  Enclosures shielding refers to conductive gaskets, apertures, windows, etc.

[Averaging problem]

Good point, makes sense.  I'm looking at differential pressure (1-2 PSID change).  I store a reading after 2 min. so the reading can stabilize.  After 2min is the rate window, which can be set from 3min. to 100hrs.

Dave

[Averaging problem]

I am using a V130.  Converted the Analog input to read pressure, once a second. I need to average a large number of input readings over a user selected time frame.  Pressure reads XX.X and time frame can go up to 100 hours.  Using it to warn if a rate change over the time frame exceeds a preset value from the first reading.

Appreciate any help

[CSV file name ?]

Joe thanks for the quick reply. 

Dave 

[CSV file name ?]

I need to have the date and time used as a file name for creating CSV files to the SD card (V130).  The CSV files will be created on average 20 times a day.  It may be weeks or months before they are reviewed, thus the need for date and time.  Any suggestions would be appreciated. 

[DT to SD as CSV]

I also have a need for the customers (V130) to convert a DT to .csv on the SD card when required.  The interval for doing this is not known, customer driven.  The data table has 8 columns and 1000 rows.  Are there any future plans to incorporate this feature for DT's?

[Best Method]

Thanks,

I have two HSC counter inputs and use those to get a total Gallon Per Minute flow.  Used the GPM to stop the Output, and restart when flow starts.  The Output runs to maintain a PPM range for flow.  The problem arose at high flow rates and running near the low PPM limit the Output would keep running until it caught up.  No acceptable with no flow.  This method worked, will try yours and one from Uni support team.

[Best Method]

The inputs a constant stream of pulses.  The pulses represent flow from flow meter.  Flow starts and stops fueling by an operator.

[Best Method]

I would like to set a coil and reset it when the High Speed counter input stops then restarts.  Trying to stop an output when input stops, then restart it input restarts. The output runs at varying rates based on input frequency changes.

[V130 Connectors]

I'm using V130's and am creating a system wiring board for our product.  Would like to mount the male side of the input/output connectors on the wiring board.  Its a way to hold the PLC connectors in place during wiring.  Also are there tab jumpers for the PLC connectors available instead of jumping with wires.

[Reading High speed input]

I'll send it to support@

[Reading High speed input]

V120 (JP 1) is jumped for pnp, JP 2 jumped 12VDC, JP3 & 4 jumped voltage input, JP 5 & 6 jumped10.2 to 15.6VDC

 

The V130 we are using is a 12VDC version.

V130 (JP1 Digital Inputs) jumped for pnp, JP 3 & 4 jumped for Voltage, JP 5 jumped for Digital, JP 6 jumped Analog.

[Reading High speed input]

I can see the Input changing in the Online Test (Input, Address 0).  Nothing on the corresponding DW listed in the High Speed Input. Both units are set to pnp.  I actually have three inputs with pulses, can't read any of them with High Speed Counter with Reset.  Swap it out with the V120 reads fine.  Tried three different V130 results the same.

[Reading High speed input]

A V130-33-TR20 replaces a V120-22-R2C in existing systems.  The inputs where setup the same High Speed Counter with Reset (Odd input active low).  The V120 reads this.  The V130 only reads if I switch it to High Speed Counter.  The system hasn't changed.  Only the PLC.  The input programing is the same.

[Reading High speed input]

I am trying to read a High speed input pulse, I0 set to DW0.  On Line test I can see the input switching, but no change reading DW0.  The only place that DW0 appears in ladder is a store function (set to 0 at startup), and math function, I/O snap in High speed Inputs.  The online test math function is active in the net.  Math function DW0 times 10. I,1 is set.  I0 is set to High speed counter with reset (Odd input active Low), I1 Freq. meas. 1000msec.

[RTC to ASCII]

Do you use MI150 "set feature for a group of operands" for the 5 MI's for the date. Then again for time.

[Need a little direction]

I did use the "links and jumps" bit "Is Active Status as stated earlier to do what I wanted.

I'm trying to set and reset a MB. Using compare =.  I selected the selected the SI252 Current display for A, and the correct Const. # for B.  When I Press the #1 I want it to set the MB, 0 to reset it.  I have the compare in the net then to a + pulse SB41 to a Set coil MB.
