Select Ethernet I/P as the protocol in the screen.

FAT 32?

Can the school save as a .cxt for you?

If you click on Save As the drop down box has a .cxt option.

Inputs going negative - below 4ma if you are using 4-20ma devices. The input devices need calibrating up or the analogue card calibrating down.

For the NS15 you use CX-Designer.

You can - I would just replace the processors with CJ2M-CPU31 - probably cheaper and the CJ1M is getting older now. You would need CJ1W-EIP21 cards. They are needed on a big network due to the amount of data they can transmit but the EIP module in the CJ2M processor is fine for what you require.

No - built in Ethernet port. Just configure the data links. Say 10 CIO words each way starting at channel 600. 600-609 will be with IP address xxx.xxx.xxx.1 and 610-619 will be with IP address xxx.xxx.xxx.2. I use the default - 192.168.250.1 and 192.168.250.2.

Use Network Configurator - a part of CX-One.

Yes but getting old now. Easier to use 2 x CJ2M-CPU31 and Ethernet between them.

Has anyone used the Modbus RTU function block that uses serial gateway on the SCU card? Success - messy - any information welcome. Looking at using it instead of the PMCR function.

Battery? These values are stored in DMs that are battery backed up.

Model number of PLC and cards?

CQM1 was discontinued years ago. Due to go in the bin.

Have you tried this mob? https://www.radwell.com/Buy/OMRON/NT20MDF121V1

Interesting - you never know what is going to cause a problem. We always blame the application - lesson learned for all of us I guess.

Also not possible to online program in a blank section - has to have something in it when downloaded to the PLC such as always off - out 200.00. Can then online edit.

OUCH! That is weird.

All good here.

Who is this idiot posting Viagra crap etcetera? Under different names as well. Has the website been busted?

How about a cable connector with an auxiliary contact?

You have to set up the serial card to communicate with the HMI - the conversion is very good but will not do that for you.

Try auto online and select USB.

Buy CX-One from Omron and update it to the latest version.

The E10 appears in my list. When you select CP1E it defaults to E20 - roll up the selection box and you should find it.
