Automating with SIMATIC S7-1200: Configuring, Programming and Testing with STEP 7 Basic Hardcover – 2 May 2018

Good book

could do with a section for entry level readers just to get them started, this book assumes that you already know how the Siemens PLC works and what the identifiers mean.

A very detailed book but riddled with appalling errors. for example, the ladder logic chapter frequently confuses the labelling of NO and NC contacts. This book has not been proof read very well at all. Very poor standard for Siemens.
