Digital Inputs/Outputs - Siemens SIMATIC Ident Function Manual

If several commands are executed in the chain for which data is returned, the position of the
data in the receive buffer "RXREF" can be set for each individual command using the
"IID_CMD_STRUCT[x].OFFSETBUFFER" parameter.
Note
"IID_CMD_STRUCT[0]" reserved for "INIT"
In the Ident profile, the "IID_CMD_STRUCT[0]" parameter is normally reserved for "INIT". If
you want to use "IID_CMD_STRUCT[0]" for another command, make sure that the reset
parameters are written into this parameter when there is an "INIT".

Digital inputs/outputs

The RF650R/RF68xR readers have four digital inputs/outputs, while the RF615R reader has
one digital input/output. The outputs can be configured in the WBM. The request and control
are via the controller. You can control the addresses of the inputs/outputs via a 1-WORD
subsegment of the process image of the reader/CM. You can enter the addresses using
STEP 7 or Studio 5000 Logix Designer in the properties of the reader in the parameter
"Digital inputs/outputs". You can access the digital inputs/outputs via the byte with the lower
value address.
The structure of this byte and the assignment to the digital inputs/outputs is shown below:
