Hi Mark and all, I used sscan-2-10-1( 2D scan ), base 3.15. I always got "Waiting for pv's to connect" after I clicked the "scan" in scan1. But it work fine when I disable the saveData in st.cmd with the same setting. It could do the scan 1 and scan 2. So I think the error was saveData. But saveData should be easy. The error was "I/O error, can't open file" though I am root. The following was some strange message I got. When I set the parameters, I got these message in st.cmd. ******************************* dbpf("xxx:scan1.R1PV", "xxx:m1.RBV") DBR_STRING: "xxx:m1.RBV" dbpf("xxx:scan1.P1PV", "xxx:m1.VAL") DBR_STRING: "xxx:m1.VAL" dbpf("xxx:scan1.T1PV", "xxx:m2.EXSC") DBR_STRING: "xxx:m2.EXSC" dbpf("xxx:scan2.R1PV", "xxx:m2.RBV") DBR_STRING: "xxx:m2.RBV" dbpf("xxx:scan2.P1PV", "xxx:m2.VAL") DBR_STRING: "xxx:m2.VAL" dbpf("xxx:scan2.T1PV", "XSPRESS3-EXAMPLE:HDF5:Capture") xxx:scan2:special:connect already in progress for link T1.
