[RTC to ASCII: Those Pesky Separators]

Hi Guys,

You can use the String tools to create any string you want. This is part of the beauty of them.

Here is an example program that takes the RTC to ASCII for the date and the time, Removes the "/" from the date and the ":" from the Time, then truncates the strings down to four chars, and then merges the two strings creating your file name.

It is also worth mentioning, that we added a few new formats to the RTC to ASCII to support files names (legal file name chars are numbers, letters and the "_").

[Dual Monitors Properties Pop-Ups]

Hi,

I run across the same problem from time to time with many programs. Here is a link to a piece of software that can help.

This program will display all of the open windows. You can select the VisiLogic window and have it brought to the main screen.

Hi Dan,

I use an extended laptop often, so I run into the same problem. Here is the trick

When it happens .............

Hold down "ALT" and then hit the space bar. You won't be able to see it, but the popped up window will actually display the default windows drop down list for that window. Then type "m" to select MOVE.

Now, just use the arrow key (Left arrow if you were extended to the right) to move the windows back into your range of view.

You can practice it with a window that is in view first so that you can see what is going on.

[Shift right (FB SHR)]

Hi, i would use some single scan conditional element, like a -|P|- contact before the shift block, or it will run on every scan.

If you would like to see what is happening with the bits, i would recommend using the memory field and setting it up like in this image. You can watch the bits shifting right. If the MSB is a 0, it will shift in a 0, and if it is a 1, it will shift in a 1.

I have attached an example as well.

[485 Programming to V-350 PLCs]

Dennis,

I am using a M90-19-R4 RS-232 to RS-485 converter.

I have Com 2 on my plc set to baud rate 19200 and RS-485. I have set the jumpers to terminated RS-485. The network ID is 64.

You can see the settings all here. If you converter has an option for half duplex try enabling it.
