Example of parameter assignment
Ident_Profile
Create a instance variable.
CMDREF
Assign a variable to the "CMDREF" parameter. This variable has the
"IID_CMD_STRUCT[10]" data type.
HW_CONNECT
Assign a variable to the "HW_CONNECT" parameter. This variable is part of the variables
of the "IID_DATA_*" type.
IDENT_DATA_TXREF
Assign a variable to the "IDENT_DATA_RXREF" parameter. This variable has the
"SINT[n]" data type.
IDENT_DATA_RXREF
Assign a variable to the "IDENT_DATA_RXREF" parameter. This variable has the
"SINT[n]" data type.
STATUS_WORD and CONTROL_WORD
Assign the cyclic input word to the STATUS_WORD parameter and the cyclic output
word for the channel to the CONTROL_WORD parameter. Per physical module, variables
are automatically created for the cyclic words. You can find detailed information on
assigning parameters in the section "Assignment table (Page 28)".
The "I" stands for input and the "O" for output as shown in the following figure. These
are assigned as follows:
• Input for STATUS_WORD: ...I.Data...
• Ouput for CONTROL_WORD: ...O.Data...
