Overview of tightening results communication
The Nexo cordless Wi-Fi nutrunner can transmit tightening results via the access point to other devices
for further processing or storage. The following protocols are available as data services for transferring
data between these devices:
•
File Transfer Protocol (FTP) which is based on TCP/IP.
•
As of Nexo firmware version 1200: Hypertext Transfer Protocol (HTTP)
•
As of Nexo firmware version 1200: File Share
•
Rexroth Open Protocol
•
Rexroth IPM Protocol
•
As of Nexo firmware version 1200: VW-XML protocol
•
As of Nexo firmware version 1400: BMW-TPC service
These protocols can also be used at the same time.
The settings for these protocols are made via the NEXO-OS operating system in the
Settings

menu, see section
7.1.1
Identification code (ID code)
The results data record of a tightening operation is uniquely identified by an identification code (ID code)
for internal or external further processing and can therefore be assigned to the tightened component.
The ID code can comprise up to 100 ASCII characters, e.g. parts of a workpiece number, production
number, serial number, chassis number, or the like.
The ID code is transferred to the controller before the tightening process starts. The internal cycle counter
or the Open Rexroth Protocol can be used for the creation of an ID code as an alternative. If the Nexo
cordless Wi-Fi nutrunner is equipped with a barcode scanner, the read valid barcode or parts thereof can
be used as an ID code.
Each data service requires time to calculate and thus lengthens the duration of the tightening cycle. This
is why it makes sense to only activate the necessary data services to avoid delays.
As of Nexo firmware version 1100, the
Mode
menu item is used to set up the ID code to identify a set of
