Question

Writing inside an array

Hello to everyone,

I use a KEPServerEX with the S7 Plus Ethernet connected with Ignition SCADA.

I have a problem writing inside an array tag through a opc client. Every time I received this message: "bad_write not supported the server not does support writing the combination of value".

I think that this message appears because clients are not enabled to write inside an array. Is there some setting to enable this functionality or the only way to write inside an array is by referencing the exact value?

 

Thank you.

See an old discussion here - "client connect kapware, set_value return BadWriteNotSupported": https://github.com/FreeOpcUa/python-opcua/issues/919

Hello,

 

This issue appears to be related to OPC-UA as opposed to the Siemens S7 Plus driver. Are you able to open a support ticket? Creating a support ticket/case will allow us to collect and review server logs and information that will help dig into this issue further.

 

Thanks,

Noah
