[New PLC startup]

Update firmware before first program download

I usually let VisiLogic tell me when a firmware update is necessary and ignore it otherwise, especially since it is a very time-consuming procedure that has risks. I never update software or firmware version on an installed PLC that is otherwise functioning.

[INFO Mode Parameter]

Thank you! I'll give that a try.

[INFO Mode Parameter]

What is this parameter under Ethernet in INFO Mode? It can be changed but does not stick through a power cycle. Can it be set through ladder?

8). What type of download?

The type of download will depend on the circumstance and preference. Download All & Burn is a great option if the PLC will not be easily available to you when it is in service.

10).  SB 168 powerup as 1

This is part of the program and is a separate issue. This thread is about what to do with a completed program and new PLC hardware.

6) Download a blank program

This seems to solve a number of glitch-type problems that can develop with Unitronics PLCs. It looks to me like (but this is just supposition) that downloading a blank program does something more than just a regular program download. It seems to clean up problems with the image storage memory and other issues. I would certainly like to hear from someone knowledgeable from Unitronics if this is actually the case. Regardless, it's always a good cleanup to perform before the PLC is placed into service.

[New PLC startup]

Call me crazy, but here is my procedure for starting up a brand new Vision PLC:

1) Install Ethernet card (if applicable)
2) Install battery
3) Power up PLC & calibrate touchscreen
4) Connect with USB
5) Set RTC
6) Download a blank program
7) Initialize & Reset
8 ) Download program
9) Install SD card (if applicable)
10) Go online with PLC and check Ethernet, battery, & SD (SB 141, SB 8, SB 217)

This procedure is especially important if you are shipping the PLC with the program pre-installed or are not the person doing the physical PLC installation.

Overkill? Am I forgetting anything?

[Reset Entire Bit Array]

Did you try Vector Fill function?

[Is there a way to make the Unilogic software interface closer to the Visilogic one?]

Regarding the HMI, in VisiLogic I can hover the mouse over HMI elements and get a lot of information (though not always enough). In UniLogic, in order to see anything you must click on the element and then the properties window is so cluttered that it takes quite awhile to discern what I need to know.

[Is there a way to make the Unilogic software interface closer to the Visilogic one?]

My biggest problem is the window with the ladder. As you can see above, you can fit at least 3x the number of rungs in the same vertical space in VisiLogic. This necessitates much scrolling, but if you try to scroll with the mouse wheel, it scrolls so slowly it feels like the mouse wheel either isn't working or is only registering at random intervals.

Sadly, all too common experience.

[Slave Port Issue]

You use the Socket Initialization Function Block to set protocol, master or slave, and port # for any of the 4 available sockets.

[Internal temp reading - SI 14]

Thanks guys!

[Internal temp reading - SI 14]

Understood. Just hoping there might be some other setting to bring that in in Farenheit, not unlike regular thermocouple inputs.

[Internal temp reading - SI 14]

Anyone know a way to get the readout from SI 14 in F instead of C?

[Date Time Stamp to Data Table]

Search this forum for RTC to ASCII UDFB.

[Question for our members: HMI Controller]

I've got customers that can't grasp the concept of an All-in-one and simply refer to it as the HMI. I think the HMI Controller terminology would be something they could understand better.

[SD Card Absense Error]

This limits SD card capacity to 32GB.

Thanks @AlexUT. The limitation is not a Unitronics limit, but is a function of FAT32 addressing. There are workarounds in Windows, but not in PLCs.

[SD Card Absense Error]

Good to hear! Thanks for letting us know.

[SD Card Absense Error]

It's not a matter of optimal - it's a matter of the PLC being able to handle such a large capacity card. I haven't checked to see what the limit might be for the UniStream hardware, but I would be certain that it would handle 32GB or lower. Just grab a 32 or 16GB card and see if you can get it to work. They're cheap and it would be an easy test. Is there some reason why you must use a 128GB card?

You can also check with support@unitronics.com to see if they see any problem with a 128GB card.

[SD Card Absense Error]

Have you tried a lower capacity card?

What causes SB310 and SB311 to go high?  Is there any way to override this?

You change the value of those two System Bits in Ladder to perform the buzzer functions indicated in the description. They do not "go high" unless the software causes it.

[Vislogic PID]

Use "PID Autotune" function blocks, not "PID".

[Speed issues with a DC gearmotor on Unilogic]

#1 - Do NOT place multiple logic threads in a single ladder rung.

#2 - It appears that you are not using the Timer correctly. Here is the Help entry for the On Delay Timer you are using. You must use the Out bit. If you are still not understanding, ask a specific question and we will help you.
