If you make L MW1 then: MB1 is byte 1 MB2 is byte 0 If you make L MD1 then: MB1 is byte 3 MB2 is byte 2 MB3 is byte 1 MB4 is byte 0 Best way to understand is to execute those command on real PLC and see in VAT table what you have. Siemens use big endian architecture, so I hope moderators will not mind by inserting external link here http://en.wikipedia.org/wiki/File:Endianessmap.svg |
