Tab. 8.20: Feedback to the MSI 430 module for reading the data structure of the PLC-5 input

The command data of all assembly instances can be recorded using "Read input".
In contrast to native addressing of EtherNet/IP assembly instances, the PLC-5 system address contains an
element offset which can be used.
The MSI 430 module supports fields (arrays) of UINT as PCCC data types. Due to the odd size of the as-
sembly instance 57, the firmware contained in the MSI 430 module assigns an additional byte, to provide
an even number of bytes.
The address scheme supported by the MSI 430 module for Read PLC-5 input is shown in the following
table:
Tab. 8.21: Read address structure of PLC-5 input
Address Data type
$N57:x UINT[n]
$N167:x UINT[n]
Example: "$N57:10" and "Total Transaction = 24" address elements 11 to 34 correspond to bytes 20 to 66
of assembly instance 57.
Note: Byte 67, which is not specified in assembly instance 57, is also transferred.
Note: The position of the word data with system state and system mode are dependent on the requested
amount of data "x".
8.4.7.6 Protected Typed Logical Read with 2 Address Fields
The MSI 430 module supports "Read SLC-protected logic input" according to the following table:
