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.

Remember Me checkbox intermittent
Mendon Systems replied to Mendon Systems's topic in Website Updates
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! -
Remember Me checkbox intermittent
Mendon Systems replied to Mendon Systems's topic in Website Updates
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.

How to write and save a variable to the PLC (FB)
Mendon Systems replied to O3Eye's topic in CX-Programmer
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. -
How can I monitoring connection between CJ2M and PC
Mendon Systems replied to juniorpeterle's topic in CX-Programmer
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.

IP/ Subnets and communication between subnets
Mendon Systems replied to Joseph 0028's topic in Computer Help and Networking
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. subnet tutorial -

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.
