Fieldbus control and result storage via WLAN

With the integrated logic in the CS351 IL compact system, single channel control can be implemented
as a gateway between the PLC fieldbus and the Nexo cordless Wi-Fi nutrunner. The CS351 IL and PLC
communicate via fieldbus. The Nexo cordless Wi-Fi nutrunner and the CS351 IL use the Rexroth Open
Protocol for WLAN communication.
In addition to an ErgoSpin hand-held nutrunner or a tightening spindle, several Nexo cordless Wi-Fi nut-
runners - limited by fieldbus - can be connected to a CS351 IL compact system. The maximum number
of transmittable results is limited by the fieldbus. The integrated logic of the CS351 IL has to contain func-
tion blocks that provide for communication with the Nexo cordless Wi-Fi nutrunner via Rexroth Open Pro-
tocol. The CS351 IL is equipped with two 24 V interfaces, e.g. for the connection of socket trays. If more
socket trays are to be used, they have to be connected directly to the PLC.
Furthermore, the results data can be transmitted in the "standard Nexo" format as a *.json file via WLAN
from the Nexo cordless Wi-Fi nutrunner to an FTP server of the IPC or database server.
As of Nexo firmware version 1200, a HTTP or File Share server can be used for transmission of the results
data.
The data may be transmitted via WLAN using one or several access points.
