how to rename simulated cdaq in MAX

[AndyClegg]

Hello,

Well it should be straightforward to rename a simulated cDAQ in MAX - right click on the simulated device in the navigation pane and select rename. However, when I try this it just keeps reverting back to the original automatically defined name. I've tried editing the "hostname" dialogue box as well, but that also just reverts back. I don't get any error message, and the simulated device is created just fine in the first place. I'm using MAX 14.0, LV 2014 etc from NI Developer Suite 2014 DS2.

- Am I only allowed to rename the numeric part of the name e.g. "cDAQ1" to "cDAQ2" ?

- Is there something else I need to do - e.g. restart MAX - to see the change ?

- I presume since I am simulating an Ethernet cDAQ that it appears under the "Network Devices" - is there a restriction on renaming for Network Devices ?

- Could a stopped NI service be responsible ? I've got NI Citadel services stopped since something was making them slow my PC down unacceptably.

Of course I've tried some of the above. Surely this should be straightforward, so I expect something is broken, but I'm not 100% sure if there is some unusual feature I am missing here.

Thank you,

Andy

Hi AndyClegg,

My name is Mitchell Goon, from National Instruments Technical Support.

With regards to your queries:

1. You can rename devices in MAX to any name of your choosing, with the following guidelines:

• Use any alphanumeric characters
• Do not use non-alphanumeric characters, such as dashes, punctuation, or spaces.
• You can use underscores within the name of the device, but you cannot use leading underscores, such as _Dev1.
• You must use no more than 256 characters.

You may wish to refer to “Configuring and Renaming DAQ Devices” under the Help section in MAX.

2. No additional steps are necessary, as long as you click on the “Save” button, located at the top, in the “Settings” tab

3. Renaming a simulated Ethernet cDAQ should follow the same guidelines as mentioned above.

4. As Citadel does not impose size limitations on databases. As such, your PC’s performance could be impacted as the database grows. You may wish to refer to the section “Database Size Considerations”, under “2. Citadel Database Structure” in the link below, which may be useful when using databases in Citadel:
