S7-Communication
Task definition
Communication with a Siemens S7-PLC.
Features
- For communication with a Siemens S7-300/S7-400/S7-1200/S7-1500 PLC with Ethernet interface.
- For the communication with a Siemens S7-200/S7-300/S7-400 with PROFIBUS/MPI/PPI an additional MPI adapter is necessary.
- The TCP protocol extension ISO on TCP (RFC1006) is used to transmit the S7 protocol.
- You can read and write the input / output / marker / data blocks / timer / counter of the S7 PLC via Node-RED.

S7 programming adaptors support the "MPI over Ethernet TCP/IP" protocol (named RFC1006 ) as server. Is there any library/source code as RFC1006 client?
