You can use SI32. If it is = with 0101 reset tour Julian display. Then if the J display =0 add 1.

Thank you! It works great. The second part of my problem is the password. The password variable looks different then the help file examples. I've tried to set it, but SB250 never goes high. What am I missing here?

It is a V1210. It is all done. I just created 20 different drums (tok me a couple of hours) and it works fine now. Thanks!

I just bought a couple of V130J PLCs and running a small program on it. It has a weigth and humidity control that I would like to put the settings behind a password. I have a couple V1210s that has multiply passwords for different access levels and it was easy to set up. However this "non touch screen" is giving me trouble. I can't figure out how to use the keypad on it. I had to set it up so the up-down arrows adjust the settings and the left-right arrows scroll through the pages. Any help would be greatly appreciated.

Thank you Joe! The reason I was looking at a cup or propeller type because this duct has a lot of dust in it that could build up on a sensor and give false or no reading.
-
I was wondering if any of you ever used a cup or propeller type anemometer? The one I found is 5-15V DC. I guess they all setup to run on a car battery.

I have a new project that requires to measure airflow in a 14"x24" rectangle duct that is 15' long. It is part of a machine and sometimes they need to to turn down the fan. An airflow meter would ensure they turn the airspeed back to the same setting all the time. I will use a V130 to keep it low budget. Thanks in advance!

Like neurocyber said, the project optimizer will point out problems like a coil being called by two different net. They will not turn on because the other net will keep it open.

Does Visilogic 9.5 works on Microsoft Surface laptop/tablet with touchscreen? It has USB port and sounds like a convenient device to carry between machines. My machines are in a dusty environment and my laptop fills up with dust fast.

My cell cerrier is ATT so the PLC can send the email to my number@txt.att.net and it come is as a text message.

You could just use the drum for the outputs. It is much easier and keeps the program clean. If you want different orders or times just make as many drums as you want. I also like to use one net for one logic. It makes it easier to find problems.

Thank you for the help. They both have ethernet card installed because in a future (when I figure it out) they have to report production data (cycle count and material/sope usage) via email to the production supervisor.

Here is my next challenge. I am running a V1210 with V200-18-E3XB on my industrial washing machine. I use one analog input for the scale to load the machine and it works perfect. The operator enters how much they want to load into the machine (400lbs) and when they load the silo that feeds the washer stops at 400. When the washing is finnished the material goes to another machine (dryer) that also has the same PLC setup.The two machine runs on a different 24V power supply, but it could run from the same if that helps. The wet material that goes into the dryer silo is around 30% heavyer. How can I set the dryer silo scale to turn off at 520lbs, 30% higher than the washer setting? I was thinking to setup an analog output from the washer plc to the dryer plc as an analog input then linealize it to ad 30% and store it as load limit. This way when they change the load limit in the washer it would automatically tell the dryer how much material it should get. The problem I see with this idea is that I am using the acm and T+ from the scale amplifyer. Connecting an analog common from a different source could be a problem that could screw up my scale reading.
-
I am not an expert by any means, but wouldn't "multiply by" 4 do it? Operator enter the desired number into an MI and multiply block will do the calculation. If the amount of sizes are less than say 40-50, you could make a button for each dimensions and the operator would only hit the desired size button instead of entering a keypad all the time.
-
I have an industrial washing machine running a sequence from the drum. I made a drum with 42 steps and 44 outputs. This is the largest sequence I need, but need a bunch that is a shoter cycle. It is a lot of work to make 20-30 new drum configuration. How can I copy/paste the largest drum configuration and just delete the steps that I don't need in a shorter cycle?
-
Every load could be different and the operator could select if he wants to split the load in half or third. He needs to khow how much he puts in (eg. 0-100) and then the next step resets the display to 0 and it goes up again. I've tested it today and it works great.
-
Figured it out. It needed another linearization block that has X1 as 4095 and X2 as 0. the first one shows the scale value decreasing the second one shows the calculated increasing value and actual weight in the next machine.
-
So I had a chance to test/play with a 1210 today and had most of the stuff figured out. Machine gets the load 300lbs and set a bit to store it. Divide by 2 or 3 (selected by keypad). Store divided value and show as desired weight. Load desired weight into the next machine showing actual weight. after loading a MB resets the actual weight to 0. All this works, but the actual weight. Since I am taking off weight from the scale my actual weight display shows decrement. How can I show increasing number when my scale number is decreasing? This reverse linearization beats me
-
So after silo loaded using a positive transition contact I can STORE the weight. Then use DIV with a numeric keypad (limited to 1-3) to divide the weight and load it into the mach. Next silo loading signal resets the STOREd value. Would this logic work?
-
Here is my new problem. One of my machine has a loading silo that holds 300lbs of material. It loads it into the next machine and when the scale reaches 0lb the machine goes to the next step. It works fine. We switched to a different material and I have to split the load to 2 or 3 equal portion. Basically I need to put an extra button (keypad) for the operator to enter 1 2 or 3. Can't realy use divide 100 or 150 because sometimes they only have 250lbs in it and they want to have equal load for equal quallity. How can I teach the machine to divide the original load 1 2 or 3 equal loads? I need to make sure that if the original load was 300lbs and I load 100lbs into the machine the next load will be 100lbs instead of dividing the remaining 200 into 3 loads again. I would greatly appreciate any input on this.
