Your Notify area contains all that information. The screen switching strobe will be your Notify Area + 2, Bit 12. So if your Notify Area is HR0001, then your screen switching strobe is HR03.12.

It's a little difficult to understand without seeing your instruction with all the parameters. But I think I know what you are asking. If DM0050 contains #0100 and DM0100 is the address you wish to compare then do a CMP *DM0050. The preceding "*" is how you do indirect addressing with Omron PLC's.

Since reading your post, I have connected to the server and I am downloading updates right now. It is slow but the updates have always been slow for me.

All in good fun! I'm sure Bob understands.

You didn't mension the space requirements. I would consider using a third battery on a seperate charging system. The small chargers are relatively inexpensive. I personally would not want to risk draining your starting power when verturing at sea. "We're going to need a bigger boat." That just came to mind.... may he rest in peace.

Bob forgot his glasses again.

There should be no problems converting the program (manually or by hand) as the instructions in the S3D8 as really basic. However, you will not be able to download the program. You will need the S3D-P programming unit to step through the program.

I tried to open it with CX Programmer and tried converting it with the File Conversion Utility. In both cases it would not finish converting for me either. My guess is the file is indeed corrupt.

I use the drill / taps as well. I've never used the Greenlee with the 1/4" hex. My thoughts on these are... if the bit hangs in the steel it will most certainly break. I use a standard drill / tap with a round shaft. This way if your bit hangs it will slip in the drill.

I believe Sleepy answered it the best he could with the information available. There are too many questions for the question given. Which one did you disconnect? Where is the communication error comming from? What is the communication error? (Red light on PLC, red light on comm card, or "Connecting to Host")? I'm also confused as to the connections you described.

I agree with you Bob. Some of the guys here at our plant have taken advantage of the 'sections' function of the newer software to segregate the machine controls or stations. (As Sleepy has outlined). I began using it when we started using HMI's. I seperated the machine's control from the HMI because we felt the machines control is most important and should not be dependant on the HMI or associated PLC programming for the HMI. The days of this non dependancy of the HMI have long passed but I still like the 'Top -Down' style of programming. It just works better in my brain. I know from your previous posts (Bob), that you didn't like LSS very much but, when dealing with a large 'top - down' program, the LSS print outs were the best IMO. The cross references were very concise and and made it very easy to hash out those large programs.

There are many ways to handle alarm events especially in the NS screens. The older screens (NT) were not so functional. They do have alarm history records but that doesn't help much for active alarms. In our field it is important that an alarm is not missed by the operator. For example, if multiple alarms are present but you are only able to display one alarm at a time, the hidden alarm may be reset without being seen. The attached code shows how we handle this situation. When the alarm happens, the screen is displayed and latched in the PLC. If a second alarm happens, the new alarm will overwrite the old one on the screen. When the reset button is pressed, only the alarm that is currrently being displayed will be reset. Therefore, the priority of the alarms are 'last in, first to be reset'. This is only one example of the many situations that you ask. Depending on how detailed you wish to get, it could be one large document. Good luck.

That is strange addressing. I wonder if that has anything to do with backwards compatibility. In Omrons pre - CS/CJ PLC's, the timers and counters shared the same memory area. Just curious.

As mentioned by Clay, the 12 hour shift will probably be the most efficient and favorable but with a little overtime. Here at our plant we have tried many 24/7 operations and we've resorted to the 12 hours several times through the years. Mon: A Tue: B Wed: B Thr: A Fri: A Sat: B Sun: B Mon: B Tue: A Wed: A Thr: B Fri: B Sat: A Sun: A This equates to 4 Hours overtime per 2 weeks.

Also you will need a Host Link Unit to connect to the PLC's. LK201 is the part no. for the RS232 model. I believe the C28 takes a different model. There is discussion in these forums somewhere with details. Edits: C28K C60K & C60P

Try these guys. K-Tron Their systems are a bit sophisticated for my taste but superior in function. We use smaller systems to feed extrusion machines.

Sleepy is correct. (see image below) Also, be sure to monitor in HEX. Monitoring in Decimal will only confuse you as this is only a representation of the actual value. On another note... you should really be using NTXS instead of NT2S software. This has nothing to do with your current problem but you may have noticed that NT2S software is unstable.

What does this mean? (The attached image below) If I click on 'Learn More', if just reads the same thing in a web browser. My updates are complete. Is it simply stating when CXONE updates were available? If so, why would it be an inconvenience? Is there a list of the revisions with descriptions? For example, what are the bug fixes, functional enhancements, new equipment support? ...just found it. I RTFM, it's in section labeled Upgrade Information. I have them. I don't know if sharing them is a good idea. It appears there are different versions for the number of seats as well as different versions regionally. Plus, the latest updates are 424MB, I don't know where it would be appropriate to upload them. We have a 3 seat license and our CX-Programmer was upgraded to V7.2.

Really?!? Which folder? I download as Bob does and have the same complaint. We have a license on a PC that is not connected to the internet, so download is a must for us.

We use this from Phoenix Contact. It looks less conspicuous when we have to get into a cabinet.

My sig. I love it!

I'm not sure about CX Supervisor, but given your printer is a dot matrix type, I would suspect your printer settings. Check settings labeled 'auto carriage return' or 'auto line feeding'.
