Apr 4, 2016 · LOGO! 8 supports S7-protocoll via TCP/IP. You can connect LOGO! 8 to KNX-Bus via CMK2000 (expansion modul). For a SCADA you need a OPC-Server (SimaticNet OPC-Server) because most fo the SCADA systems do not have a LOGO! or S7-200 driver included.

Although LOGO uses the S7 Protocol, some small changes (new connection functions added) were needed in Snap7 to manage it as PLC Server by a Snap7Client. You can use LOGO as Client connecting it to a Snap7Server or you can connect a Snap7Client to a LOGO set as Server.

Server and S7 Client ........................................................................... 22. This application example offers a completely configured S7 connection for LOGO! ("LOGO!" for short) for communication with a SIMATIC S7 controller.

S7comm (S7 Communication) is a Siemens proprietary protocol that runs between programmable logic controllers (PLCs) of the Siemens S7-300/400 family. It is used for PLC programming, exchanging data between PLCs, accessing PLC data from SCADA (supervisory control and data acquisition) systems and diagnostic purposes.

This application example offers a completely configured S7 connection for LOGO! 8 ("LOGO!" for short) for communication with a SIMATIC S7 controller. You will use a LOGO! switching program connected to an S7 project, where you can test the connection and can freely expand it.

This chapter explains the advantages of the S7 communications protocol compared with other protocols and the S7 programming interface for PC/programming devices (SAPI-S7).

This document describes using the Siemens S7-300/400 TCP/IP Master driver to communicate with a Siemens Logo! Basic module. Products

Dec 4, 2012 · Siemens have no official API for LOGO!. From what I know from other users here, is not going to come up with one. You can however try this LOGO! API Middleware server. https://www.ambersys.net/ Your LOGO! needs to be accessible over the internet. Reading the Data from I1-I4, M1-M4, AI1-AI4, AM1-AM4. Can Trigger Function Key F1-F4

Jun 5, 2019 · S7COMM (S7 Comunication) The S7Comm is a proprietary Siemens protocol that runs between the programmable logic controllers (PLC) of the Siemens S7-300 / 400 families and the most current S7-1200 / 1500.

Shows how you can use Node-RED together with the Siemens Logo8 1FB08 with ethernet. Reads the outputs Q1-Q10, writes a memory location M1 with the S7 protocol.
