Siemens S7 PLC and C# APP S7

What is the APP S7 Library

APP_S7 is an S7 PLC driver written by Alan Phillips that works with Siemens PLC's and with Ethernet connections. This means that the PLC must have a Profinet CPU or a profinet/ethernet external card (CP-343 etc). APP_S7 is written entirely in C# and aims to be the most flexible S7 PLC communication method. The APP_S7 Driver requires a license for long term operation. This can be requested by contacting:
