Go back and look at your sample code - My first PLC programming experience back in 1989- A Modicon P190 Available for the low, low price of $6,000.00 Then you had to buy the family specific tapes to load into it for another $1,000 - The P190 weighed about 50 pounds, and I have memories of lugging it outside to a chemical tote-filling structure at Monsanto with a very long serial cable connecting it to the $25,000.00 Modicon 584 PLC for troubleshooting. After walking uphill in the snow of course. Joe T.

Search the Help for "bootstrap". It will tell you how to get your specific model into boot mode. Joe T.

It's been literally years since I've had to work from a printed copy of ladder. Reminds me of the days when software was DOS-based and it came out using character graphics. Great tip, though. I'll continue existing as TE 5. Joe T.

The question has already been answered as "yes, the frequency on the basic HSC configuration is in Hz." Integer hertz. Little known Visilogic trivia- if you need frequency resolution greater than 1 Hz you can use the "Frequency Measurement based on HSC" function block cleverly located in the Utils->Immediate menu. It returns frequency in 0.01 Hz resolution. Very handy for speed control applications where you don't have the luxury of an encoder; i.e. a prox on a bolt sensing speed. That's actually pretty clever. 😄 Joe T.

Video is supported on HMI units that have the -B10 in the part number (the "Pro" version). It's not available in the PLC only product. If you have this, the Video option magically appears in the Media tools - Which model do you have? Joe T.

UniLogic never did run very well on Win 7 as it had to install SQL Express 2012 alongside for it to work. It runs so much better in Win 10. Submit your question to Official Unitronics Support at support@unitronics.com The newer versions of UniLogic will be able open a program made on an old version. You'll also have to update your PLC firmware, but that is not a big deal. Joe T.

I see the oldest version in "Previous Versions" is 8.0.1. Download that and see if it works. If it doesn't, contact support@unitronics.com and ask for version 4.74. Joe T.

Yes! I hadn't seen that, but here's something Ofir posted: https://support.unitronics.com/index.php?/selfhelp/view-article/remote-io---urd-0200e That information really needs to be added to the manual, but I do know that Unitronics only has so many technical writer resources. Joe T.

Additional historical information - the V120-12-R1 is really old. I checked my price sheet archives and the part number changed to V120-22-R1 back in 2006 when there was a major hardware revision. I don't remember what that was. I would not use this PLC for anything other than a trainer. As Flex says, it is "possible" to do what you want but you'll spend way more time trying to stack the data up and then getting it out the serial port. Go with any of the newer PLCs that have a micro SD card. Joe T.

@Cara Bereck Levy - Do you have the additional information on the UniStream Remote I/O? Joe T.

Do this first. It's probably got something to do with whether you have the inputs set to sinking or sourcing and what you're applying to Input 0. Are you applying +24V or a contact closure as referenced to 0V? Joe T.

You don't need logic. When you configure the input as a HSC it will start incrementing on it's own in ML 0. Download your program and try it out! The HSC value is not retained through a power cycle. If it's something you want long term you'll need to continually copy the value off to another ML and copy that value back to your HSC with the start-up bit SB 2. You You're not. Each pulse is 0.1 kW, so the value in ML 0 represents kW with an implied decimal at xxx.x. For example, when the value in ML 0 = 1234 the actual power is 123.4 kW. You can set the display format to match this. Joe T.

The newest release of UniLogic supports servo axis synchronization of up to four axis using the EtherCAT communication option. Unfortunately, you have neither. A Vision probably doesn't have the processing speed you need to get the encoders to line up. What is your number of degree tolerance for the encoder positions matching? How fast is it spinning? (Master Frequency) How fast do the axes need to sync up? Joe T.

Per the latest revision notes, this feature was recently implemented in UniLogic - I doubt that it will ever be added to Visilogic, but you never know. Joe T.

That sounds exciting. What make and model of encoder did you get? Joe T.

Unitronics distributor here. Not a Unitronics employee, so do not take my comments and opinions as the official Unitronics position. Consider yourself extremely lucky. Hopefully your distributor gave you the heads-up on long deliveries at the beginning of the year. Here in the United States, delivery has been six months on Vision products since April. Apparently there's one chip also used by the automotive industry that's causing the delay. They don't know when delivery will get back to "normal". We did receive a large shipment this month and supposedly we'll get more that will cover our backlog going back to March. They are not going to re-design the Vision to use different chips. Any new designs are in the UniStream product line. My gut feeling is we will someday get caught up. I would recommend you order additional spare parts and sit back and wait. Joe T.

The best sensor for high speed is an encoder. You could put a toothed pulley on the main shaft and couple it to an encoder mounted next to it with a timing belt. The PLC has a high speed input on I0 designed for this. Joe T.

It stores the linearized value immediately upon setting SB 80. As you mention, move the linearized value out in the net after you set SB 80. You can load up SI 80 .. 84 in the next network and start the roller coaster again. Joe T.

Yes it does. Click on the green link to expand it. Joe T.

You'll see when you download it and look at the numbers. A is the MF you enter into the block and B will be the numbers to the left of the decimal, which is what you're interested in. C will be the decimal part. You may or may not be interested in this number. Joe T.

I'm always happy to help someone who's willing to put in the work to try to fix the problem themselves. Joe T.
