Communication made easy
between S7 PLC and PC
Communication Adapters for S7 Controllers
The access to an S7 PLC from the PC is supported by default with newer models. The S7-1200 and S7-1500 series usually already offer the possibility to connect an Ethernet cable and thus easily establish a connection. With many older models of the S7-200, S7-300 and S7-400 on the other hand, there was no need for this at the time of development.
However, the new requirements from IIoT and the Industry 4.0 presuppose access to your S7 controller. To implement this, you do not need to invest in a new controller. With the S7 adapters from DELTA LOGIC, connecting older S7 models is very easy, fast and cost-effective. Depending on your requirements, you can use the PROFIBUS, MPI or PPI interface of your controller. For the PC side, there are options for Ethernet, USB and the serial RS-232 interface.
You want to use an Ethernet port of the PC and connect it with PROFIBUS, MPI or PPI of the PLC? Then the ACCON NetLink PRO compact is the right adapter for you. If you prefer to use USB instead of the Ethernet connector, we recommend the ACCON NetLink USB compact. For the connection of MPI to your serial RS-232 interface of the PC simply use the ACCON MPI Adapter RS-232.

The compact all-rounder among the programming adapters between PC and S7 PLCs
ACCON-NetLink-PRO compact is a handy communication and programming adapter between PC and S7 controllers. The electronics of the ACCON-NetLink-PRO compact is placed in the case of a PROFIBUS connector. Thus, the adapter is very small and handy.As all-rounder, the ACCON-NetLink-PRO compact can be connected to the PLC via MPI, PROFIBUS and PPI. The ACCON-NetLink-PRO compact automatically detects the current bus settings of the PLC.
Perfect fields of application
As programming adapter to create and change the PLC program
As communication adapter for visualisations
As communication adapter to access the PLC's data
For remote maintenance via internet, intranet, dial-in router
Varied ranges of application
Programming S7 controllers with STEP 7
Changing S7 programs via a company network (intranet)
Projecting HMI devices with WinCC flexible
Connecting visualisations to S7 PLCs via TCP/IP (RFC 1006)
Logging S7 data via TCP/IP (e.g. with ACCON-EasyLog)
Remote maintenance of S7 controllers via internet (VPN, e.g. via the DELTA LOGIC Connectivity Service)
Convincing and varied
The communication of the ACCON-NetLink-PRO compact to the PC is effected via TCP/IP so that it can be used for remote maintenance purposes via router, intranet and internet. The ACCON-NetLink-PRO compact can be configurated via its integrated website. For the security of your facility, the access to the website is protected by a password.The ACCON-NetLink-PRO compact supports the S7 communication via RFC 1006 (ISO on TCP). Thus, TCP/IP communication processors (e.g. CP343-1) can be replaced by this adapter. However, projected connections are not supported. Furthermore, the ACCON-NetLink-PRO compact supports the parameterization of DP-Slaves via DP-V1 (class 2).A driver for SIMATIC applications (ACCON-S7-NET) is included in delivery. The ACCON-NetLink-PRO compact is fed by the connected bus. Alternatively, you can use external 24 VDC (e.g. with this external power supply).

ACCON-MPI-Adapter RS-232
€364.76*
A S7 adapter for direct access
The ACCON-MPI-Adapter allows the connection of a PC via its serial interface to the MPI interface of a S7 PLC. If you prefer to use the Ethernet interface instead of the serial interface of your PC, you can thereby use a higher transmission speed. For this we recommend the ACCON-NetLink-PRO compact.
Perfect fields of application
As programming adapter to create and change the PLC program
As communication adapter for visualizations
As communication adapter to access the PLC's data
Varied ranges of application
Programming S7 PLCs with STEP 7
Connecting visualizations with S7 PLCs
Logging S7 data (e.g. with ACCON-EasyLog)
Convincing and varied
The ACCON-MPI-Adapter RS-232 uses the same communication protocol as the PC adapter. Thus, the ACCON-MPI-Adapter RS-232 can be used with any software supporting the PC adapter.
Technical highlights
Low-cost solution for programming and visualization
Serial transmission rate up to 115.2 Kbps
MPI speed up to 187.5 Kbps
