3.5.2 Single-Tag mode: SOPAS object trigger control
The object trigger control settings define the status of reading gate (open / closed). The de-
vice sends a reading result to the PLC after each reading gate. The function block uses this
mechanism in order to read the UII, the PC-Word and RSSI values of the corresponding
transponder.

must be defined, that the trigger window is opened via a "Command" and closed
when a "Good Read" result is received or after a defined period of time (e.g. 1000ms).

3.5.3 Single-Tag mode: SOPAS output format
The output format defines the content of the telegram that is sent by the device as soon as
the trigger window is closed. This telegram is evaluated by the PLC. Afterwards the function
block used the information to create addressed read / write commands. The SOPAS output
format must be structured as shown in Figure 7 in order to use the function block with the
Single-Tag mode.
