Hello nanchi; You will find the basic bit-logic instructions for Step 7 in the following attachment, taken from the STL for S7-300/400 manual: https://support.industry.siemens.com/cs/ww/en/view/109751814 Each instruction is analysed in the following pages of chapter 1. There are also Word-logic instructions in the same manual that you could be interested in., You can compare with manuals for LAD, FBD and SCL to see how these instructions are codified in different programming languages For more details on each logic instruction and how tha Status word bits of Step 7 and the RLO bit (result of logic operation) are affected by each, look up the instructions section of the S7-300 Instruction list manual (see chapter 9): https://support.industry.siemens.com/cs/ww/en/view/31977679 Hope this helps, Daniel Chartier |
