For the MSI-FB-PROFIBUS gateway, data set 1 was divided into five input data blocks, with data
blocks 1–4 each containing 12 bytes and data block 5 two bytes.
For the MSI-FB-CANOPEN gateway, data set 1 was divided into four blocks, each with 8 bytes.
You will find more detailed information in the corresponding section for each gateway.
• Data set 2 (32 bytes) contains the test values (CRCs) for the system configuration.
See table "Overview of input data sets 1-3 (basic settings for Modbus TCP)" below
• Data set 3 (60 bytes) contains the state and diagnostic data for the various modules, with four (4) bytes
per module, with the controller module comprising 3 x 4 bytes. Details: see table "Meaning of module
state bits" [chapter 3.3.5]
• Data set 4 (60 bytes) is currently filled with reserved values.
The following table provides an overview of which data sets are provided by which gateway.
