The trigger variabel is a word variable. You can either set it Bit wise if you are using slice access. See: 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? Or you can use overlaying with the AT keyword. See: How do you program the overlaying of tags with the keyword "AT" in the STEP 7 (TIA Portal)?
