hi flukky, that a Problem or a feature of Modbus. Even when you just need a bit, it takes a register with a whole word. You can just compare this word with value "1" or use the slice-instruction. which is described in following FAQ: How in STEP 7 (TIA Portal) do you access the unstructured data types bit-by-bit, byte-by-byte or word-by-word and symbolically?hope this helps, regards, |
