Kratmel's reply was before Steve's. But both just approved together. Looks like same observations. It would be interesting to see if this is firmware related. cheers, Aus

Joe, do you mean like this? cheers, Aus

If only even 1/7, SI34 still works. By "working week", I meant 5/7. But if you've got it going, no worries. I only mention the HSC usage because sometimes quirky problems are introduced unnecessarily into user's projects. cheers, Aus

Vasovas, to me you are focussing on the wrong SI. From what you are saying this machine is working in a full working week, or 7/7 environment. Use SB2 to store SI34 to an MI sequence that compares if the numbers match. If the numbers match don't do anything, but if they are different then it is a new day. This is covered by Flex saying there's a host of SIs to play with. Also, my question as to whether you actually need to be using HSC? cheers, Aus

Probably not likely, but wondering if you also need to allow for what is in the topic below. Also wondering if along with the topic's subject, you actually need to be using the HSC. cheers, Aus http://forum.unitronics.com/topic/6118-hsc-resets-dw-counter-to-after-power-cut/

John, you haven't forgotten to log in have you? Works for me this morning! cheers, Aus

My Dad often walked into a room and completely forget why he went in there. Great Dad, rubbish firefighter. cheers, Aus

Flex, my biggest issue is I'll be in transit in the workshop or home doing something, and attending to a distraction will make me put the component down. After finishing dealing with the distraction, and the other 5 that happened during the initial one, can I find the carefully placed component? Nup! My wife and I constantly use the excuse of Ross River Fever as the cause of this. It's one of it's symptoms....you can't recognise something in plain view. So you can now start using it too! cheers, Au ohh oh, the phone's ringing..... where did I put that s?

but if you do this, understand that at quicker rpms your readings are going to be all over the place. At lower ones it would be reasonably ok. Sanyc, do you understand the logic behind this statement? As it's an inverse type thing, it can be hard to get your head around. Think about it... 1 RPM = 600 counts to be converted by maths. 2 RPM = 300; 5 RPM = 120; 10 RPM = 60; 20 RPM = 30; 30 RPM = 20; 60 RPM = 10 and notice now how the rpm numbers are starting to get all over the place, as you are extrapolating numbers that will by their very nature jump in large amounts due to the maths. At any time, but more so at higher rpm, you'll also run into issues with over-lapping of input reads that might just miss the 100ms count time, but be added sort of erroneously into the next one. Think of the inverse relationship they same way a linearisation will work if you only have the input from 0-10 and the output 100.....you're only going to get an output of 0, 10, 20, 30 etc. Not any of the numbers in between. Thus the smaller the primary count, the better. cheers, Aus

Ever since it started raining, all my wife has done is look through the window. If it gets any worse, I'll have to let her in. ...ouch! 🙂 🤛

The timing period has to be exact, whatever you decide on. That is the entire basis of the concept. Basing it on scan time is not sufficient. This is why it uses the interrupt in Vision, as it is exact and interrupts the scan, if necessary, at the exact time interval. Someone else can perhaps comment on your logic, as I don't use Unistream. But your deviation observations match what will happen with the basic timing error, as it will increase proportionally the quicker the shaft spins. cheers, Aus

Not necessarily. That was just to cater for the slower interrupt on older Visions. Enhanced ones can also do 1.25ms. The principle is what I was showing you. The smaller the time the better, you just tailor your maths to suit. But at something doing a maximum of only 120rpm you don't need to be going overboard. cheers, Aus

Did you know ants never get sick? It's because they all have little anty bodies.

In both cases I suggest you take up "not for industry use" with the manufacturers. I feel sure they'll disagree most strongly. The huge advantage is ease of implementing remote action/monitoring when only a few I/Os are needed at each remote location. The "other" one used to be available, but they are changing the fundamental build, and it doesn't appear to be finished yet. Like I said, I'm not directly promoting them, but thought that they might be a possibility for Vidmas's location given the relatively simple parameters described. They sit in the enclosure, connect to your LAN, and send/receive info to/from the plc in such a manner that you don't need to do any "networking" in the plc at all. cheers, Aus

Not promoting someone else, but do you know these things exist? Don't use protocol as such, and simply mirror what is wanted from each end. Other species are available, but they are rare. Available: goggles TCW122B-RR Supposedly being updated....have been saying that for ages...I've been waiting....waiting...waiti 😴 : https://relaypros.com/Relay/Relay/CAT_RELAY4_MirX_ETHERNET cheers, Aus

Twitter asks what I'm doing. Facebook asks what I'm thinking. Google asks where I am. The internet has turned into my mother. 🕵️‍♀️

Further to Joe's request, Are you sure about this? Can you hook the 1210 in again to check? cheers, Aus

Jungle, it may not help your exact issue, but have a look at Joe's detailed post on how to set EX-RC1s up in the link below. Although it is for Visilogic, it might be of assistance in resolving your issues. Some other areas....... Are all of the components updated to the latest firmware where possible? All power and earth lines done correctly? Locations of I/Os match in physical layout and in the program? cheers, Aus http://forum.unitronics.com/topic/4165-setting-up-two-ex-rc1/?do=findComment&comment=21520

Did you do the install using Right click/Run as Administrator? If not, uninstall completely and start again. After re-installation, check that the visilogic.exe is set to run as Admin as well. cheers, Aus

Sadly not my joke....... My wife asked me why I was whispering in the house. "Because Mark Zuckerberg's listening," I whispered. She laughed. Alexa laughed. Siri laughed. 🙈 cheers, Aus

If you don't want to do it Flex's way (which will still involve some maths), although it is in Visilogic this example shows the principle of how to do it very easily. At 120rpm max you don't need anything fancy like high speed inputs or timers. I'm not a Unistream user but feel sure that setting up your own 1.25ms "interrupt count" should be very easy. You may be able to go even smaller for greater accuracy...I don't know. cheers, Aus http://forum.unitronics.com/topic/4599-totalizer-to-gpm/?do=findComment&comment=17077

de003, FYI, LOTS of things with "usb" connections are just a tiny variation on an item that used to have a 232 port, but now have an onboard usb converter fitted to make them more "use friendly" to people who expect connections to be simple. The trouble is that most of those items will install drivers that completely stuff up current drivers that are working perfectly. It is a bit of a minefield and something to be aware of every time you plug something industrial looking into your puter. System restore etc is a must before doing anything. Some of Unitronics info is squirreled away, but most is there if you look hard enough. All by easily navigating a screen. Be thankful you're not looking through large paper books like us oldies had to, to learn stuff. 📖 👓 I have a few bookcases full of such stuff. cheers, Aus

Have a look at this. Cheers, Aus http://forum.unitronics.com/topic/5271-totalize-flow/?do=findComment&comment=20226

John, what's wrong with tape? Jeesh...even way in the future Sigourney still uses it to attach various gizmos onto her "kill all the aliens" weapon! I always laughed at that. 👽 Yes...screws are good. cheers, Aus

What are these exactly? They are the likely cause of issues if not correct/good enough. cheers, Aus
