Hi, I looking to develop (for fun) a Scada app and need an OBD-2 driver for Intellution Fix32 or iFIX. OBD is On Board Diagnsotics and is an industry standard in the car industry. A lot of manufacturers use it, and basically you can connect your laptop via RS232 to the car. The OBD protocol is also known as ISO 9141/2 Keyword Protocol 2000 Ian.

Update, Think it works now......looks like have to format all drives, PLC clear, pull battery etc and start from absolute blank and then it seems ok. Phew! Ian.

Hi all, Is this a flaw??? Have set a cpu keyword in GX IEC and it works, if I try to upload or download MELSEC only then I'm asked for the password, however, if I try to upload out of the PLC SYMBOLIC then it never asks me for the password........and as a result the user gets the entire source code......ok except the 'comments' I thought the whole point of the keyword protection was to protect the PLC code? This means our competitors can go out to our system, connect their laptop and steal our code!.....the whole lot bar the comments within the ladder. Any ideas? I just want to make our code within the PLC as secure as possible. Ian.

Hi, Thanks for the info......I kinda thought there were a lot of pins for the functions I was hoping there was there. Btw, we already use a PC similar to the VersaView 200R you mention, from ADLINK. http://www.adlinktech.com/PD/web/PD_detail...q=8&id=9&sid=53

Hi all, Ref. Panelview 1500 I'm interested to use the Panelview Plus Logic Module with our own LCD, i.e. I'd like to bolt up the Logic Module to the back of our own VGA touchscreen LCD's. I assume the Logic Module interface the VGA signals and touchscreen signals via the dual connector as shown in the manual (2711P-IN004C-MU-P). The reason for doing so is in order to use our own high-brightness, daylight readable 18" & 20" LCD modules which use ELO touchscreens. Any info appreciated, Ian.

Now that is wierd..........I was told specifically today (by Mits Scotland effectively) that the MIT driver would not work with Q (new-Q, not QnA). We did try it, and I tried setting the driver to AnA as well as AnS setting on the driver and it didn't connect. Monday will see us having another bash at it. Ian.

Hi, GX IEC Developer (ver 4 & 5) & Q02 cpu. I decided I needed a POU that will only run say every 4000ms (4 secs), so I created a new entry in the task pool and specified:- Prio=10 Interval = T#4000ms I'm finding that the POU doesn't run for 4 secs after everything else is running, but from that point onwards it seems to be running full whack. I'm using a Mits GOT930 terminal which works by way of direct memory access, so the parameters on the LCD are actual PLC memory locations. I can see them delay for 4 secs but then continually refresh. There's no other POU's updating the same memory locations. Any ideas? Ian.
