[Data Table column width to be saved]

Sweet! Thank you @Cara Bereck Levy!

[How can I convert DI/DO read as 16-bit words to coil status with Modbus 485?]

Use VisiLogic to go online with the PLC and inspect the values of the registers.

You should be able to use a Vector Struct function block for this.

Hi all, a request to the creators for Data Table saves in Visilogic to remember column widths.

Seconded.

Of course there are perhaps dozens of settings that should be saved by project in VisiLogic but aren't. And why doesn't VisiLogic pre-fill the file name when doing a Save-As, like every single other Windows program in the world?

1).  Change the battery?  Even us humans sometimes don't work properly when we're a little tired.

PLC had been sitting on a shelf for 6 months and the last program was still in it and working when I powered up (the previous program was not "burned").

2).  Do a full Init & Reset?

No, probably should have tried this.

3).  Drop the baud rate progressively and make sure that you do the same in Device Manager.  On my 130s I always have them running at 9600, mainly because of this being the same speed I run the 485 modbus loops at and it prevents confusion.  Perhaps W10 has again  done something else to serial comms!

Did try dropping the baud rate. Note above that I tried on two different computers - one was Win 10 and one was Win 7. Both were able to connect to other Vision PLCs using the same serial cable.

For me, in this case, it is important to determine whether it is a hardware or software problem.

According to you - you saw in the buffer RX from PC and panel to PC TX.

Question: Did the answer reach from the panel to the computer? I think not, so the TX panel line is either dirty or damaged.

So the test is to measure the voltage of the logic "1" at the TX output of the RS232  PLC port.

There should be a level close to -10V relative to GND. If it is not there - then ADM202EA - failed.

Agreed. Isn't it amazing that a piece of electronics can sit on a shelf and fail without any activity whatsoever. I probably won't have time to troubleshoot further since I now have a working Port 2, but it would be nice to know what happened.

So another idea. Is it possible that SB 314 (Block PC access to PLC. OFF by default. When ON: access via VisiLogic, RA, etc. blocked) is ON?

Great suggestion! Unfortunately I was already in the process of installing the serial module when I saw your comment.

End result: Got the V100-17-RS4 module installed (very difficult by the way) and the PC connected right away using Port 2. Still doesn't work on Port 1. Everything else about the PLC seems normal and functional. And, of course, SB 314 is off.

[V130 Serial Port Fail]

No, I checked that. And anyway, I have been using this PLC for programming work for a couple of years with no problem and have never opened it up.

A second serial port is cheap, so I'm going to install one this afternoon and see if that works.

[V130 Serial Port Fail]

I have a V130 that I use occasionally for some programming work that I suddenly can't communicate with via serial comms. In INFO Mode I can see TX & RX occurring during handshaking, but VisiLogic gives me the dreaded Communications Error box. I've tried two different computers with the same result (one of which is Win 7 and the other Win 10). Both computers will communicate just fine with a V1210 using the exact same cables, so this appears to be a problem with the V130. INFO Mode shows that all the comm setting are correct in the V130, as follows:

COM 1 - RS232

Prtcl: PCOM

Settings: 115200, 8, n, 1, N

Ign Brk: N

Any suggestions on the best way to approach troubleshooting the problem?

this subroutine is called conditionally

You should avoid conditional subroutine calls. It's not just timers, but any coil will be left in limbo when the subroutine is not being called.

But when i test my program, the Set/Reset coils arec energized at the same time.

I think you're misunderstanding the power flow designation in VisiLogic. When a coil is energized it will show as red when online in VisiLogic. The fact that the coil is a SET coil, RESET coil, or direct coil is irrelevant to showing it energized. Whether a SET or RESET in VisiLogic, it's still the same coil and will be visualized the same. What you need to be looking for is complete power flow from the left rail to the coil.

And what tests I can preform to narrow down my issue with the connection between the two V700 PLC's

If you can Ping both PLCs from your PC, then the next course of action is to go through all the initialization and configuration blocks with a very careful eye. There are LOTS of entries and one wrong number will bring the whole thing down.

Thanks for reporting back with the solution!

[Unable to install UniLogic on Windows 10 PC]

Do you have administrator privileges on your PC? Did you turn off UAC? Did you run the installation file by right-clicking and selecting "Run As Administrator"?

[actuator drive problem on PLC outputs]

SB 2 is called the Power-Up System Bit. It is on during the first PLC scan and is off thereafter.

[actuator drive problem on PLC outputs]

It will depend on what's turning on that output. If it's a SET coil, then use the Power-Up feature to RESET the output. If it's a direct coil, then you will need code to stop the coil from being activated at power on.

[Missing vertical scroll bar in VisiLogic 9.8.80]

It may be related to a Windows graphics setting. Make sure you don't have any scaling or other display settings that are other than the default.

[IO Comm error on power up USP-104-B10 and email issue]

If the PLC program has I/O modules set up in the hardware configuration and you don't have those modules connected, this is normal. Just close the message and proceed as you wish. If you don't want the message to appear, either connect the module(s) or change the program to remove the I/O modules.

[2 timers- OFF and ON time]

Here is how I would do it. For this to work, the MB 13 needs to be a Toggle button, not just a momentary contact.

[For Language/Music/Animation Geeks...]

Hilarious! Reminds me of the Bad Lip Reading series. They're all pretty funny, especially the football ones, but this one should appeal to everyone. I suspect it was a lot easier due to the robots and stormtoopers.

Just place a Numeric variable on the HMI screen and check the box for Keypad Entry.
