They have the 50 or 60 Hz noise rejection settings on Unistream 8 ch AI, I suspect it is a software based notch filter. A ladder based filter while not impossible would be a bit over my head. Good notion, Nobody likes false alarms or measurements!

Yes, it has that inherent tendency to send us all crazy once in a while! And as always thank you all for sharing your knowledge! Be it expert or novice, it's all appreciated.

It's not a big deal, i can TCP/IP connect and correct the MTU RTC offsite. More a matter of me remembering to do it. Unistream generates and emails daily reports (7am to 7am next day). Report was an hour late the day after dst change. No one lost their head of over it. Now the RTU's at meter vaults.... serial modbus only (over RF), no IP, correction would require a physical visit. i suppose i could construct a one time modbus write register that could change system clock. Thanks for all the feedback.

Any chance of Network Time Protocol with selectable sync intervals? What about a simple setting for auto Daylight Savings Time correction? It's concievable that DST correction could be constructed with ladder logic. However a menu section would be easier. thanks.

MODBUS is a big deal in my genre of PLC applications. The more flexible and feature rich your product's MODBUS communications abilites are the GREATER the appeal your products will have with not just me, but plenty of others. Enhanced Vision has a pretty awesome MODBUS feature set. Unistream should exceed it by far. And yes.... I'll give credit for the periodic MODBUS. You've made an easy to deploy MODBUS setup template. Just don't take away the user definable parameters of it's predecessor under the assumption that "no one will ever need a setting greater than x." And then go on to set it at a fixed value internally. That was an egregious error. I am eagerly awaiting MODBUS mixed R/W and I recall others asking for things like dynamic parameter tags.

Love the Uni timers PDF. Great stuff, just need the likes of it for every Unilogic function

Flex, It was the other way around. My unplanned transfer was to the Vision. See story below: I bid a brand-new automation project with a unistream 15.6 and and 4- V430's as MODBUS RTU's. The customer wanted the largest screen available for the MTU. Once I had everything laid out on the bench I started my RF radio data communication development and testing. Discovered the UniLogic serial MODBUS timeout was fixed at 500 ms. This caused major problems in the proper collection of register data from my offsite slaves. Of course Unitronics support tried to convince me that I had a problem with my third-party integrated radio/modems. So I took one of the V430's and wrote a program to make it a MODBUS master. The vision worked flawlessly, this was my proof that it was a Unilogic issue. Bear in mind visilogic let the programmer specify a Modbus timeout value. Unitronics offered me a V1210 to use for the customer while a software fix was being constructed. So now with my Unilogic program development halted due to technical difficulties I changed gears and developed a complete master automation program for the V1210 (it took me weeks). When the beta release for Unilogic came out I got to start all over again (V1210 program became worthless to me) developing a complete master program for the Unistream (which is now installed and working great). I can't even begin to quantify how much lost time, money, and sleep this caused me. Such is life, gotta keep moving on. Ultimate motivation for UniStream: BIGGER SCREEN

It's my understanding that the team in Israel is working on a complete Unilogic help section. It's much needed!! I did a large VisiL to UniL program translation and it was challenging to say the least. Finally got 99% of it equavicated to what the V1210 was doing.

Glad you were able to get it going quickly and simply. I too was accustomed to Vision's internal jumper source/sink config and AB SLC500 I/O and had to read deeper into things to see what they were doing on extender input modules. You will grow to love Unitronics PLC's, their performance to price ratio is amazing. There's a learning curve, but such is life. Happy developing Lepton!

The N, P, and common terminals have to be wired for sourcing or sinking per technical papers included with the module. I worked with a V1210 and a 6 module IO behind an EX a month ago. Memory a little fuzzy but I think I seen the same "all inputs true" conditions with N and P terminals floating. Hope that helps! I was using separate 16 IN and 16 out modules, looks like you might have a combo I/O module. Guessing input section would still have P, N, and COM terminals.

Cara, I know you are. I certainly respect and appreciate you and the UniTeam. I'm old school enough to be a textual learner. Since Windows 95 I've been clicking the windows style help index then: searching, reading, and getting revelations.

This isn't the first nor the only thing I have noticed that would make plain sense to have included but isn't. I've learned/trained my subconscious to right click and select "run as administrator" on all trusted third party software I install. One thing I must give credit to Unitronics, Inc for is that they are very responsive when there is a legitimate issue with their software. I had a MODBUS timeout issue a few months ago and they made changes to Unilogic software to rectify it for me. Now it works and my customer is happy. I've been told German and/or Japanese PLC companies are not so quick to help when such issues arise. I'm still nudging for MODBUS mixed R/W in UniStream and getting the help fully loaded on unilogic. It was a rough transition from VisiL to UniL for me.

Utilized this, is helpful. However for Visilogic veterans transitioning to unilogic a help page with examples is always a welcomed sight.

i'd be happy with Uni to Vision. My last project used Vision slaves and a Unistream master. Uni to Uni would be a given. I don't expect Uni to third party. the vision R/W mixed was Vision only (no third party) feature. I can't emphasize enough how incredibly valauble the MODBUS R/W mixed I/O is! Cuts airtime in half on RF data modems.

Is there any chance of the periodic modbus seeing a retry parameter? In water treatment SCADA the data exchange is (in my region of the US) via RF data transcievers where outside RF interference can occasionally impede a successful MODBUS data handshake. In the Vision line the "retries" were an available parameter in the MODBUS config block. I will also take the opportunity to (again) petition for the development team to offer the MODBUS mixed R/W data feature (available in the enhanced vision series). That is an awesome feature that sets Unitronics apart from it's competitors!

The integrated VisiLogic help library is excellent. It has never left me questioning after a good read through.

OK, wow. Would never have guessed that. Not relevant to any applications of mine. We will reach a time when the UTC will exceed the number 32 bits can express. I'm not going to calculate when that will be, to late at night for that. Made me think of the IPv4 to IPv6 scheme. Thanks for the swift and concise reply.

sent files and version to support. I hope this isn't just something I'm doing wrong. Regardless I'll be happy to see resolve. Thanks.

What are the "UTC to Date Time" and "Date Time to UTC" function blocks for? Could not locate reference in the textual help. I know RTC= Real time Clock and guess UTC is universal coordinated time? What sparked this question is that I was wanting to have a data tag that would show the date in MM/DD/YYYY for display in an HMI element to use as a "counter reset last on date mm/dd/yyyy" . The RTC date stuct parses out the elements of the date as a whole, so I'm guessing I would have to piece it together with logical functions? Just wondered if there was an easier way (I'm always looking for those). Thanks -hw

OK, did not realize the two opposing forces could work together as a "bit true for duration of touch". Setting up two lines on actions: set bit pressed, reset bit released works exactly as desired. Thank you Saragani!

Still no success with trends displaying on a running basis. Watched videos and read the help twice, spinning my wheels.

Cara, I have the data samplers established, have FIFO trends on HMI, I seem the have all the parameters set. Having two issues: It only seems to display one curve at a time. Other issue is the curve stays at zero even when the sampled variable is 90 (scale 0 to 100). I read thru the help before posting last night. See example below. Trying to create it's parallel is UniLogic.

Dear Community, How do I see two (or three) trend curves at the same time as seen in Visilogic? Thanks All! Sincerely, Hotwires

Dear Community, How does one link an HMI element to a bit in a manner where the bit is only true for the duration that the HMI element is held to touch? In visilogic I used the HMI link to bit and then linked that bit to a TON timer. To reset an hour meter numeric element the operator would press and hold the HMI element for 5 seconds, the timer would go true, a PTC contact would trigger a RESET NUMERIC coil; then Happy, happy, happy. Now not so much. Is this achievable in UniL? Actions seem to be latch oriented. Thanks All. Sincerely, Hotwires

Dear Community: How does one make a bit load an HMI screen? UPDATE: Found it, ACTIONS will link a bit to a LOAD HMI.
