Variable configuration of the communication data width
The communication of the MA 2xxi with the fieldbus system can be configured with a vari-
able data width; the upper limit is restricted by the fieldbus. For EtherNet/IP, a value between
4 and 480bytes (240bytes each for input and output data) can be set.
The small data lengths (< 28 bytes) are particularly of interest for use with bar code scanners
(BCL). The larger data lengths are, on the other hand, relevant for 2D-code scanners (hand-
held scanners, LSIS) and RFID.
Notice!
The representation of the (Rockwell) control is usually set to double word (DINT, 4 bytes).
Please observe that in this representation, the byte sequence can vary in contrast to the read
code. We thus recommend creating the settings using SINT.
After all parameters have been set in the planning tool/control, the download to the MA 258i
takes place. The set parameters are now stored on the MA 258i.
Afterwards, all MA 258i parameters should be stored via upload in the control. This aids in
retaining the parameters during device exchanges, as they a re now also stored centrally in
the control.
