Tim you are the freaking best in RU-vid, how can I support your channel?

@TimWilborn, these videos are awesome. I'm a 20 year C/C++ veteran getting back into PLC programming and your videos are making so easy for me to look like a rockstar ("How did you figure this CCW thing so fast!?"). Thank you, thank you.

These are so helpful! Thank you!

Thank you. This couldn't have come at a better time.

Hi Tim, you're videos have been extremely helpful for students like me. Keep it up! Thank you so much.

Tim, me acabas de salvar la vida. Muchas gracias por esos excelentes videos te recomiendo sigas así. Saludos desde México.

Tim - your going to make me money! thank you sir!

Tim, I dont make comments often. Like this is my 3rd in my whole life. But I'm commenting because you seem like a good fella and your vids are proper helpful. Thanks mate

One of your best, Tim! Please touch on why 4-20 is used way more than 0-16. Thanks!

Hey Tim, love your videos. Just a question when you a dividing the raw unit in half for the scaling you divide 4095 in half to get 2047.5, but wouldn't you count zero as a number? so 0-2047 and 2048-4095 would be equally divided in two so you could just put 2047 in the scaler? Just wondering if I'm up the wrong tree here. Keep up the good work.

Tim, I love your videos!!! I was wondering if you could do one on an RTD plug in. I am used to setting an RTD up on RSLogix 500, but for some reason I am super lost on this platform

Hey Tim, thanks for all the help you provide to us students, its truly invaluable. I'm currently using one of the Micro820 trainers and am trying to scale the 0-10V Analog input to the Voltmeter analog output. I just cant seem to figure out how to get the Analog output to work with the scaler. I appreciate any help or advice you have to offer. I'm used to RsLogix500 and CCW is pretty new to me .

I noticed something when I tried this. When I would go online and run the analog sim up to 20ma, the engineering value in the tag slowly dropped. Meaning: usually the value will bounce around but for some reason the value dropped very gradually from bouncing around 28300 to bouncing around 28200. If these numbers confuse you, I was using an 2080 IF2 and also only had a 220 ohm resister so the math was a little different.

Thank you for your videos..but please do you have a circuit diagram for the wiring in this video

Thank you for the videos. What is the best way to introduce an offset to the output of the SCALER? For example, if my SCALER Output is displaying 0.5 when it should be 0.0.

Hey Tim, I was wondering if you could explain when best to use a local variable versus a global variable? Thanks!

Hi Tim! Is there any way to stabilize the values ​​of variable AnalogMaScaled? The decimal places vary too much, which is a problem for me, as I need to work with precision.Thanks!

I’ve got an 820 where we use the add on 2080-if4 analog input card. A 4-20mA temperature sensor failed and all I have in stock is an RTD with a 2 wire 4-20mA puck that takes a max 30vdc input. When I calibrate the transducer I confirm my ma signal across full scale then connect to the input card the signal (at -15 deg) displays full scale 122 deg because the input is 27mA. I confirmed this with 2 transducers and both transducers work on test bench to a ControlLogix analog input card. Not sure if my transducer will run on 10v and I don’t have a spare analog card to test as I don’t want to risk blowing anything up at 24v. Do you think this will work to bring my signal to a voltage input? What voltage were you running to your analog device?

Hi Tim, thank I you for your videos. I am using a micro 850 to build a control system as part of my final year university project and your videos have been the saving grace in helping me figure out this project. I did have a question that I am hoping someone could help with. Is there any over voltage protection on the 2080-IF4 face mount modules? I have looked on line and found nothing after many hours of searching. My interest is in preventing damage to the module should the pot in the potential divider circuit be damage and the full 24 volts be see by the analog input pin. I have had a pot fail during installation and I would rather build a voltage clamping circuit to protect the module if it does not already have over voltage protection.

Tim,I have a pressure transducer 4-20 ma 0-100 psi. How do I scale to measure feet? I would like to open a valve at 26 feet and close the valve at 32 feet. Can you point me in the right direction?

Tim Do you have a video on how to convert 0 to 10 volts to 4 to 20 ma ???. Thanks.

How to convert 4 word data change to single real data

Hi i just want to ask if the sensor that has 0-5V output are posible to use in the plc that require 0-10V analog input.

Will ths or something similar work on the output ?

Hi Tim. I would like you to take me a doubt I'm with an analog card 2080_OF2 (micro850) your output from 4 to 20ma is connected to the input of Powerflex525. I used a scaler block but the values came out different than when I use the direct signal generator on the Inverter input. Why does it happen? Analog Signal Generator Card 20ma = 100hz 20ma = 100hz 16ma = 67hz 16ma = 75hz 12ma = 34hz 12ma = 50hz 8ma = 11hz 8ma = 25hz 4 ma = 0hz 4 ma = 0hz Thanks Tim.

I'm trying to figure out the principle operation of 4-20mA signal. Lets say, we have a RTD sensor and wanna get input on a PLC I/O inputs which take 0-10VDC. If we connect on the current loop a resistor (in order to convert the signal and take the voltage measurement for PLC), that's may cause drop voltage, and therefore, current flow restriction. Obviously the restriction depends on the value of the resistor. SO, how is that possible to get 4-20 mA constant current on our loop, without its resistor affects the current in our circuit?

Hi Tim, I have a Balluff BUS series analog input/digital output sensor. I can’t figure out how to set it up in studio 5000. I have this sensor being used my a proprietary PLC in my plant but it’s connected to a Bekoff plc. In that instance it measures distance. In the Input card, the white wire is in the signal, and then brown and blue is power. I tried to set it up this way in studio 5k but I’m getting some weird numbers. I’m using a Flex analog card btw. When I put my hand in front of sensor, it will go from 32000 to 10000 to 8, etc. I can’t get it to measure from 32000 to 0. Can you figure out what I’m doing wrong. In the analog card properties, I’m using 4to20 milliamperes.

What is the cost of your trainer?

could not find Any_to_real only any_to_LREAL in my block. Help?

Hello, thank you for this vidéo, i will make me save 100 Euros ! (4-20 mA / 0-10 V converter). Does it work with a Micro 810 ? I want to connect a water pressure sensor 4-20 mA to a analogic input of a Micro 810, this sensor is allready connected to an ATV (2 of the 3 wire of the sensor, the common and the Signal, it's to vary the speed of a pump) and i measured 24 V dc in the sensor. How can i do ?
