Param instructions

Using the "Param_RF68xR" or "Param_RFID181EIP" instruction, the configuration data is
sent to the Ident system. In addition to this, the instruction resets the required start values of
the "HW_CONNECT" variables for the reader channels (read points). Note that this
instruction always needs to be executed first before other instructions can be executed. The
instruction must be executed each time the controller or module is restarted.
Instruction "Param_RF68xR"
Figure 4-2
The input parameter "LARGE_CONNECTION" is supported only by ControlLogix controllers
as of version "5.0". You also require the Logix Designer as of version "21.00.00" and the
RSLogix 5000 software as of version "20.00.00".
If the parameter is set (value = "true" or "1"), the maximum frame length is increased from
240 bytes to 1035 bytes. If the parameter is enabled, you must also enable the options
"Connected" and "Large Connection" in the parameters "MSG_READ" and "MSG_WRITE" of
the message variables.
