Description
Diagnostics on the last transponder access
Indicates the client interface via which the last transponder ac-
cess to this read point took place.
The prerequisite is that the "Parallel" or "Diagnostics" option is
set in the WBM.
Possible values
• PNIO: Access via PROFINET
• OPCUA: Access via OPC UA
• WBM: Access via WBM
• XML1: Access via the XML channel 1
• XML2: Access via the XML channel 2
• XML3: Access via the XML channel 3
• XML4: Access via the XML channel 4
• EIP: Access via EtherNet/IP
• PB: Access via PROFIBUS
• READPOINT: internal access via the read point
The read points of the device can scan for transponders in-
dependently. This is the case, for example, when at least one
user application has started an asynchronous scan command
or when a configured trigger was started with RF600. These
events can also overlap in which case they can no longer be
clearly assigned. In this case, the value "READPOINT" is al-
ways used instead.
