Internet PLC Forum

I appreciate the quick response. Its good to know this function runs outside of the PLC and is crystal referenced.  I did some testing with my scope and within the range I need it looks very stable and clean.

Thanks

Very good. Thank you for your quick resolution of this issue.

I was doing a quick test program when developing a MT8050iE HMI interface.

I noticed a complier error when it reacts to this bit of code with a simple error in it.

I am running the latest Beta, latest Java on windows 7

When you do a compile to test the code, it apparently sees the code problem, and flashes the complier error message, but it remains on the screen for about 1/100 of a second (just a flash) , and then returns to the ladder screen, no error message etc.

If you didn't know the regular process it goes though compiling , you could be surprised.

I have a program I wrote for F2424 on TL6

I wish to move this program onto a new machine using Fx2424 and TL7

How can this be done?

I updated the driver to V1.03 as suggested (I had this already installed but downloaded it again) and followed the rest of the instructions which were well documented  - thanks!

I downloaded to the HMI.
I put the Netgear FS-105 switch back in the machine.

Same problem, PLC no response flashes on the screen.

The PLC no response appears roughly every 10 to 20 seconds and updating halts on the screen. The HMI hangs for say 5 seconds, then starts updating again. In another 10-20 seconds the hang repeats. The TRI PLC is not stopped and continues to operate and scan as normal.

If I swap out the switch, the problem is gone.

I've ordered another switch which I hope will be a work around with the issue.

I made sure the software was updated and checked settings and was still having issue. I used a small 5 port netgear switch for my machine network. I swapped cables to make sure I didn't have a cable issue and moved them around  on the machine to make sure I wasn't getting RFi from switchers or A servo drives, still not change.

I swapped the netgear switch for a different switch (an old net gear switch) and the problem went away.

Not sure if the problem is netgear or TFx2424 or the MT8050i. I contacted KEP on the problem and they said the MT8050i is an older product and that the driver could be causing the problem.

So I have a workaround for now.

Is the MT8050 current or do you have plans to switch to a more current model?

I'm using Fx2424 connected to MT8050i HMI via Ethernet through a small switch used only between the two devices and my programming PC. In my application the display works well and is only used as a display of information, no input.

The issue I have s that occasionally the display pops up a window that says "PLC no response" which displays for a couple of seconds then disappears. I assume this is happening because the PLC does not respond to the HMI requests for updates in a timely manner and the HMI times out showing the error message.  

Where would I change a setting to allow more time before this message displays? I've looked in the HMI application and don't see anything, possibly this is in the OEM driver for your PLC?
