The worst offender was one who used his handy box cutter to press buttons on the touch screen.

Yeah, that and ball point pens. Ugh!

Looks like it was @Cam who was on the right track.

Good to hear. Thanks for letting us know.

[Can't increase number of LED's; Variable Graph]

Sure thing. What version of VisiLogic are you using?

[Could I re-order SI250]

What are you trying to do with SI 250?

[Can't increase number of LED's; Variable Graph]

I just tried it and had no trouble creating 30 LEDs. Try re-starting VisiLogic and/or rebooting your computer.

I have done something quite sneaky. I have been unable to replicate the fault, the button works for me every time, I suspect the operator has a bad aim.

I have swapped the plc's without telling them. Will be interesting to see if the fault is then reported on the other machine.

 

This is smart! Please report back with the results - we must know!

[Jazz Display not working]

Thanks for reporting back!

I could be wrong, but I believe these screens use resistive touch, not capacitance touch like phone screens. With resistive touch it's okay for the finger to be insulated. I often use a pencil eraser on my development PLCs to keep them pristine.

Keep in mind that this is a holiday week in the United States. You might try sending an email to support@unitronics.com. I don't know if they are working in Boston, or might forward to Israel, but it's worth a try.

I've seen a particle of dirt get under the screen protector and cause intermittent fail. I've also seen the touch property of the screen fail completely, but it's rare.

Make sure the screen is clean and if the plastic screen protector is still on the screen, remove it. Confirm the operator isn't inadvertently touching the screen elsewhere when trying to push the button.

You didn't respond to this.

[Samba Screen sensitivity]

Another possibility - these screens can only register a single touch at once. We're all used to multi-touch screens on our phones and these screens won't do that. If there is anything else touching the screen, the second touch won't register. Make sure the screen is clean and if the plastic screen protector is still on the screen, remove it. Confirm the operator isn't inadvertently touching the screen elsewhere when trying to push the button.

Did you perform the screen calibration from Info Mode?

[Download error, can't get past it]

I've never seen the second message you show, but that looks like you're trying to update VisiLogic, not the firmware on your PLC. To update the firmware on your PLC, connect the PLC with the computer running VisiLogic and confirm you have a connection (Connection/Get PLC Information), then select the 4th tab over (tool tip says Operating System), then click the Check button. After that, follow the prompts and be prepared to wait about 5 minutes while VisiLogic updates your PLC firmware. You should then be good to go.

This is a Job Board. Are you looking to hire a programmer to handle this, or at least help? If so, please feel free to email me at blanier @ arc-controls . com (remove spaces).

If you just want a few questions answered, post in the Vision PLC Series and VisiLogic forum and you should be able to get the help you need.

[Unistream Modbus limitation]

Break it up into multiple reads.

[Unistream Modbus limitation]

IS this MODBUS? There are limitations in the MODBUS standard for register reads.

[Modbus TCP/IP Slave Configuration]

Do I understand you correctly that you are trying to read 255 registers at once via MODBUS? I believe there is a limit to how many registers you can read with a single Read Holding Registers command (a MODBUS limit, not Unitronics). Try breaking it up into multiple reads.

[V350 and InTouch TCP/IP]

Post your code for the V350.

[Condition to close a socket on V700]

Yes, timeout values will impact performance in this situation.

[Math function to analog output]

Just use any unused MI to hold the value that will change depending on the state of MB 31.

 

[Condition to close a socket on V700]

If the connection is lost, the socket is already closed, is it not? Isn't the socket being open the definition of a connection? Just reconnect. In fact, if you gate the socket connect function with an inverted contact of a bit that is on when the socket is open, you can trigger a reconnect as often as you like and it will do nothing until the connection is lost.

 

[Math function to analog output]

Perhaps I don't understand what you're doing because it seems simple and obvious what to do. Use a buffer MI to store the value you want to go to the analog output. Use two rungs, one with a direct contact of MB 31 to store MI 20 to your buffer MI and a second rung with an inverted contact of MB 31 to store MI 22 to the buffer MI. Use the buffer MI in the Linearization function block.
