I have a configuration with a siemens 315-2dp that has a profibusslave : a profibusmodule of an ABB S4 robotcontroller?
type of the card : DSQC 352.
Hardware configuration in S7 is online (when looking online) no busfaults, by using the periferic inputs and outputs I can communicatie with the slave, but when I trie sfc 14-15 (dp read-write) to have consistency, I have an error output at the sfc 14-15 : 80B1 : "The length of the specified destination area is not identical to the user data
length configured with STEP 7."
Although I have configured 8 words in out in hardware and at the sfc14-15 I also have 8 words.
Could it be that sfc14-15 is not always supported by older slaves?
