This is an open source Ethernet library for interfacing ARDUINO / ESP8266 / ESP32 natively with Siemens S7 PLCs. The CPUs 1200/1500 and S7-200 are also supported.

• Full PLC memory access.

• PDU independence, i.e. the data that you can transfer in a single call depends only on the Arduino memory availability.

• Helper functions for data conversion (Big Endian --> Little endian)

• Three memory models for footprint optimization.

• Uses standard Arduino Ethernet library i.e. it can coexist with other clients/servers in the same sketch.

• 3 ms to read a PDU into the internal buffer, 24 ms for 1024 bytes into the external.

• An Arduino with an Ethernet Shield (with W5500) in which to load the examples

• Alternatively, a NodeMCU board or Esp32 board

• A Siemens PLC equipped with Ethernet port or Communication Processor.

• Or if you don't have access to one then you can use PLC Sim for testing.
