9.9 RUN/IDLE flag functionality
When establishing the connection between the EtherNet/IP scanner and the evaluation unit the 32 Bit
realtime header is exchanged via the EtherNet/IP connection manager . Within the header the RUN/IDLE
flag is transmitted which allows to control the functions of the evaluation unit .

9.10 Setting the Requested Packet Interval (RPI)
It is recommended to set the RPI within the PLC to half of the desired update time of the evaluation unit .
Example: Requesting the transponder UID every 60 ms => RPI = 30 ms
The outputs / RFID communication of the evaluation unit have a data update rate of 12 ms,
therefore the shortest sensible RP interval is 6 ms .
9.11 Configuration assembly 102 structure
The assembly 102 is used to transfer the configuration- and parameter data of the evaluation unit . The
length of the configuration data is fixed to 64 bytes (32 words), only the first 40 bytes are used . Each
channel requires 8 bytes (4 words) .

Table 9: Assembly 102 (PLC configuration output)
On PLCs manufactured by Schneider Electric it is possible to create the configuration assembly via
the ESD file .
On PLCs manufactured by Rockwell this is only possible if the version of the programming
software RSLOGIX is > 19 .
If the PLC does not support configuration via an EDS file, the user is required to program the PLC
