ACCON-NetLink-USB compact is the compact communication and programming adaptor between PC and S7 controllers. The electronics of the ACCON-NetLink-USB compact is placed in the box of a PROFIBUS connector what makes the adaptor very small and handy. As all-rounder, the ACCON-NetLink-USB compact can be connected to the PLC via MPI, PROFIBUS and PPI.

Assembly Installation and assembly have to be carried out according to VDE 0100 / IEC 364. As the ACCON-NetLink-USB compact is an IP30 module it has to be built into a switchboard. For secure operating please keep the maximum environmental temperature of 60 °C in mind.
Connect the 9-pin SUB-D plug to the MPI or PROFIBUS interface of your S7 controller. Installation of the USB driver When connecting an ACCON-NetLink-USB compact to the PC for the first time, the operating system tries to install a suitable device driver. This could take a while and continues as follows:...

Latest driver and firmware versions can be found on our web site at www.deltalogic.de in the section »Downloads«. Installation Software The driver ACCON-S7-NET can be installed by executing the file »SetupAcconS7Net.exe« from the DELTA LOGIC Automatisierungstechnik-DVD (<DVD-drive>\S7-Adapter). Set PG/PC Interface 1. Open the SIMATIC PG/PC Interface.
BUS SETTINGS The ACCON-NetLink-USB compact can be used with three different bus systems: PPI, MPI and PROFIBUS. Configuration example: MPI The MPI configuration contains station-related settings and net-related settings. The most important setting of the bus configuration is the station address.

- using S7-200 - older Siemens S7 CPUs - if the ACCON-NetLink-USB compact is the only master at the bus When using the autobaud function the initialization lasts a bit longer because the online parameters have to be determined. It is possible that the autobaud function does not work correctly at slower transmission rates (e.
