I went a full week without a problem so I thought everything was fixed but today I have had to login in four times. It's really strange!
-
Well at least it isn't just me that is having the issue. I feel better now. The login always works OK but having to do it several times per day is just a PAIN!

I have had a problem for the past couple of weeks with the website singing me out unexpectedly. the interval ranges from several times a day to once every two or three days. I am not having this problem on any other websites so I don't think it is a security software issue.

That module will not work for high speed counter inputs. You need a pulse I/O module such as the CJ2M-MD211 for high speed counters.
-
The "D" and "DM" addresses should be interchangeable. If you enter a register as "D0" in the PLC then it should be "DM0" in the HMI.

You could either make your 'ZeroO2' into a data entry variable instead of a constant or you could create another rung similar to rung #3 which would move the correct value into the 'O2Time' register. Of course you will need some way to enter the desired value such as a touchscreen.

I have used a similar setup to monitor communications to two remote sites using an encrypted ethernet tunnel. The main PLC periodically sets a bit in the two remote PLC's. The remote PLC's turn their bit off after 5 seconds. If the bits do not toggle a communication error is logged.

The FVAL(449) instruction should do wat you are looking for.

The basics are:
1) Use the FIND$(660) command to return the position of the first comma in the string in hex
2) Use the LEFT$(652) command to extract the characters to the left of the comma to another string
You will probably want to subtract 1 from the hex value returned by the FIND$ command so that you don't get the trailing comma when you use the LEFT$ command. You may also want to use the DEL$ command to clean up the data left in the receive buffer.

Try using the mnemonic P_EQ which CXP interprets as the Equals Flag.

I suspect that the signal coming from that transducer is not DC but is an AC signal and that the high voltage peaks on the signal are destroying the AD041 module input channels.

Your problem is the subnet mask. With a mask of 255.255.255.0 PLC1 can only talk to other devices in the 10.125.34 subnet. If you set the mask to 255.255.0.0 like the other two PLC's it will work. You really should do a little research into how subnet masks work.

Take a look at the BSET(071) instruction. It should do what you want.

It appears that they are having the same problem again today. I am unable to access the site.
-
It's working now. Apparently they went down around 3:00 AM and came back up around 2:45 PM.
-
It is working OK again.

The exact same issue is back again after being gone for over a year.

That depends on which model of the CP1E you have.
-
"H" bits retain their state when the cpu is stopped or powered off. "W" bits are reset to OFF when the cpu is stopped or powered off.

Yeah, version 2.10 is quite old. I'm a bit surprised that tech support didn't have you check the version. There were a few serious bugs in those early versions of EBplus. Version 5 seems to be pretty stable.
-
Have you talked to Maple Systems tech support??? My guess would be that there is a problem with the DF1 driver.

You might try checking the font settings under Tools/Options/Appearance to see if they somehow defaulted to the wrong font setting.

You need to display the "Address Reference Tool" window on the CX-P screen. Each time you select an object in the program by clicking on it that window will display every program rung which references it. When you click on a reference in that window it will take you to the corresponding rung in the program.

Along with Greenshot you may want to install a PDF printer device such as PDF995 or Foxit so that you can print your screenshots as a PDF file.
SETR instruction

You should download a copy of the W474 manual from Omron's website. It has much more detail of the instruction set than the CXP help files.
