I have a RF615R device and I can make it scan and read tags using the web management interface.

However, when trying OPC UA I only can see the result of the last scans, but scan or scan-start actions don't work.

I've tried it using python, an opcua browser and the app at https://support.industry.siemens.com/cs/us/en/view/109769038

In all the cases the reader blinks in red and I get error 17 from https://support.industry.siemens.com/cs/mdm/109973678?c=122868449419&lc=es-NI

I'm using firmware 4.2 , connection with the opc ua is happening without any problem, both in anonymous or using certificates and access credentials.

Using opc ua, I can read info on the last tag read, but I can't make the device scan tags . I only can make it scan tags using the web management interface.

This is what I can see in the logbook:

and this in the service log:

Any ideas of what can be wrong of I can be  missing?

Thanks.

Hello,

could you please download the configutation from the device and add it here? (it can be saved by clicking the floppy disk in the web interface)

btw. thanks for adding so much information about the problem. That's really helpfull.

According the logbook entries, it seems, that the read point is always in scanning mode. It is not possible to call Scan or ScanStart on a read point which is always in scanning mode. Please try the following steps:

1) Call ScanStop first and then try to call Scan or ScanStart.

2) If this does not help, have a look at the configuration of the device in WBM and ensure, that there is no trigger configured to the read point. If there is a trigger please remove it and load the changed configuration. Then try calling of Scan or ScanStart again.

Hope this helps.

Hello, thanks for your help,

for 1) still it does not work:

ERROR

3037258832 | RsOpcUaServermain | 5640 | E4FE0600 The given command is not allowed for the current working status of the device. (Readpoint: Readpoint_1 Command: ScanStop Write access not allowed )

 

For 2)  If I undestand correctly your suggestion, config is still ok:

but the problem persists

If you want OPC to control the reader, the 'parallel' option needs to be deactivated.

 Thanks so much, that solved it.

According to https://support.industry.siemens.com/forum/es/en/posts/rf680r-opcua-communication-with-kepware/328947/?page=0&pageSize=10 I understood it was the opposite: parallel meant you want to work in parallel . Great to know it's not that way.
