Hell h2; You are right that the information is dispersed, but it is available. S7-300, S7-400 and S7-1200 are Big-endian. S7-1500 standard data blocks are Big-Endian, Optimized blocks are Little-Endian. Programming Guideline for S7-1200/1500 https://support.industry.siemens.com/cs/ww/en/view/90885040 See attached screenshot. Also look at table page 19 of the following manual, which discusses extended instructions of the S7-1200 and S7-1500 CPUs, allowing to read/write in both Little- and Big-Endian format. SIMATIC S7-1200 / S7-1500 Comparison list for programming languages based on the international mnemonics https://support.industry.siemens.com/cs/ww/en/view/86630375 Hope this helps, Daniel Chartier
