I am trying to backup the controller that I am working on. The progress gets to 2% and then the dialog box goes away. The backup process doesn't finish. Has anyone encountered this problem before? I have done backups on other controllers before without issues.

I figured it out. The datatype and the global variables isn't used. The datatype exists at the PLC side but it isn't used anywhere. Someone made it and then deleted the usage of it at the HMI side. I deleted the unused global variable at the HMI and now it's find. I went back and deleted the datatype at the PLC side so there's no more confusion in the future.

I modified and edited some datatypes at the PLC side. The problem is the HMI side doesn't update and now I have a build error. I even created new variables to try to get the HMI to update datatypes but it's not working. Does anyone know why this happens and how to solve it? Do I have to delete the datatype / variables and then start again? It's very annoying.

I have a new project for a semi-auto testing station. The station needs to be movable so it can be placed near another machine when in use. When not in use, then this test station needs to be moved away and stored. The operators will do a product changeover for this process. I have been thinking of using some EIP devices and then connecting to an existing CJ2H PLC nearby for control. The main reason here is to reduce cost. Another reason is to share the tester that is already connected to the CJ2H PLC (further reducing cost). My question is how do I prevent EIP network errors if the testing station is moved away and then these EIP nodes disappear. The EIP devices are a Keyence 2D scanner and a SMC manifold. Is there a good way to do this?

I don't see this DATERD instruction. Is this new?

Indexers don't have to be servo controlled. It can be controlled using a VFD as well. Depends on how much you want to spend and what you need it for. They are generally used as rotary indexers (look at Weiss) but can also be linear (Camco Precision link conveyor).

My local Omron rep. didn't suggest this digital license method. It's good to know that this method exists. For now, we will label the dongle and tie it to the PC with a steel aircraft cable. Hopefully someone will not just throw it away. If there is money still on the project, I will buy a spare dongle to keep around just in case.

I just got my first Soft-NA application. The software is installed and everything is working fine. I am worried that at some point the USB dongle will get lost out in the field. Has anyone experienced this? Can I duplicate the dongle as a backup or would I have to contact Omron to get a replacement?

Uninstall all CX-One or just CX-Server?

I was trying to do an update and something went wrong. Now whenever I open CX-Programmer, I get this message about CX-Server. Any ideas how to fix this?

I think I know what's going on. I checked the maximum number of user alarm logs and it's set to 2000. I looked at the alarm file that I got over ftp and it does in fact have 2000 entries. However, the log file contains all the alarms and some of them I don't care about. For example, it's logging the operator alarms like (load parts, remove parts, scan new box, etc.). About 1800 out of the 2000 entries are these sort of 'alarms'. This is why I am only seeing about an hour's worth of actual 'errors' where the machine stops. The rest of the buffer is filled with 'warnings'. I don't think there's a way to define what actually gets logged. Not sure if there's another way.

I do see a scroll bar but no luck. Even when I scroll, it's only showing around 50 alarms.

All of the user alarms are configured as level 1. The alarm viewer in historical mode is set to show only level 1 alarms. I really thought it would be easier than this to set the number of alarms that is shown.

I checked the HMI and it's only showing 50 alarms in the alarm viewer. So not really useful at all right now. It looks like I will need to use the save to the log file option. I remember doing this for another project. I had our intern ftp the files out daily so we can see what happened overnight. It would be nicer if we can look at the screen with more alarms (like 8 hours for a shift's worth).

How can I increase the number of logged alarms in alarm viewer when using historical mode? The number of alarms seem to restart on its own and doesn't log alarms back far enough for me to get any useful information about machine stoppages. I seem to be only getting about an hour's worth of alarms.

My understanding for the NX102-9000 controller is that it can't control servo axes. The controller description says 0 axes but my machine builder is telling me otherwise. I would think the -9000 suffix would indicate something inherently different from the other -1000 series units. What am I missing? I am not sure what it means for number of 'controlled' axes and number of 'used real' axes from the manual.

I had a weird problem with their EtherCAT expansion card on a XG-X vision controller. It would cut off downstream communications when trying to connect using a daisy chain configuration. The only way we got it to work was to put the XG-X with the EtherCAT card at the end of the chain.

Is there a system variable from the HMI that lets me know if a popup is active?

I will have to try using the USB option later. I ran out of time and had to leave. The machine is being powered down for shipping and will arrive at our plant in two weeks. I will try connecting again when the machine arrives. Thanks to all for the help and suggestions. I will give an update in two weeks or so.

I unchecked the boxes in the Synchronization dialog box. It tells me there isn't any data to transfer. I also tried the same with the boxes unchecked for transfer from controller. It then gives me the safety PLC dialog box. I say 'OK" but it then tells me there's a network communication error.

I have a NX-SL3500 safety PLC attached to a NX-ECC203 coupler. How do I upload the safety program from this unit? It says the upload failed but doesn't say why. I attached some screenshots.

No, I haven't. I didn't know this function exists.

I am getting an '0C0B' error on the NX_SerialBufClear instruction once every few weeks. I don't know what is causing this and also don't know how to clear it. The serial port is connected to a Zebra handheld barcode scanner and it's used by the operator to scan incoming boxes for traceability. 99% of the time this instruction works and nothing happens. When I get this error, they are no longer able to scan the boxes. The only way I have been able to clear the error is to do a soft restart on the card. I go to the configuration and setup for the bus coupler in Sysmac Studio. Look for the serial card, right click on it and then select restart.

Sometimes I get this dialog box to reflect default values during synchronization. What are default values and why do I get this dialog box?
