Fieldbus parameters for ProfinetIO and ProfinetIO M40
The table below only lists specific parameters for ProfinetIO. For the general parameters, see Fieldbus Parameters General.
Field | Description | Default value |
|---|---|---|
Device name | Name of the device | |
Fieldbus node IP address | Format is 0.0.0.0 |
|
Subnet mask | Format is 0.0.0.0 |
|
Gateway | Format is 0.0.0.0 |
|
Max ADI size | Not valid for M40. Choose between the different application data instance sizes to be set as a maximum. Data consistency is only guaranteed for data mapped over one single ADI, that is, if the data to be sent is larger, or broken over two ADIs, data consistency cannot be guaranteed. Setting a maximum ADI size, which is equal to the sent data type size and mapped correctly to the total frame size will guarantee data consistency. The maximum data size to use for sending cyclic data, which must match the data size used in the Fieldbus master. Max size ADIs will be used until less than that size remains to map. For example, If Max ADI size is set as 8 bytes, then that will be used for mapping until less than 8 bytes remain, then 4, 2, 1 bytes will be used to transfer the rest of the data. |
The parameter Device name identifies the fieldbus module on the PROFINET and uses the syntax described in RFC 5890.
