•
8: 2.0 W
Settings outside the specified values mean that the default value
of 1.25 W is used.
For UHF readers:

Diagnosis
These variables serve diagnostics and tracking purposes of the plant via OPC UA. You can
use these variables both with an OPC UA application and with a PROFINET application as
main application.
Requirements
●
OPC UA application
For the diagnostics values to be available also in the case of an OPC UA application as
main application, the "Diagnostics" option needs to be set in WBM.
●
PROFINET, PROFIBUS, EtherNet/IP or XML application
For an OPC UA client to be able to connect in addition in case of a PROFINET,
PROFIBUS, EtherNet/IP or XML application as the main application, the "Parallel" option
needs to be enabled in the WBM. In this case, the Diagnostics option is automatically
enabled as well. Please note that write access is no longer possible for OPC UA clients
as soon as the "Parallel" option is set.
