Hi Pedja, For sending/receiving failsafe data you have to choose in the hardware the right datatypes, for example MS. Then you have a certain amount of data to send and to receive, 16 Booleans and 2 Integers. For every F_SENDDP to every F_RECVDP you have the same amount of data communication. F_RCVDP have to be called as first block into FC13, F_SENDDP have to be called as last block into FC13. Please look in the handbook S7 Distributed Safety - Configuring and Programming You have to call all further failsafe blocks from FC13!! |
I hope that the answer will help, if you have still questions, don't hesitate to ask me. |
