Dear All, I am running into a hanging issue while performing scans using higher level software due to a WRITE INVALID caused by lower-level EPICS PVs. The occurrence is intermittent. From what I can find on line this *could* be due to how SCAN filed is setup in this database for the relevant PVs. I am not entirely sure if that could be the case. Any help would be appreciated. --The specific error I see in the IOC shell is the following. This is for one of the PVs. 2018/12/28 17:46:07.974527 SSH1 XF:07BMA-OP{MC:03}TrajInitPlc-Read: asynError in write: 10.7.130.93 write error --And camonitor returned the following. XF:07BMA-OP{MC:03}TrajInitPlc-Read 2018-12-28 17:46:07.974595 0 WRITE INVALID --The PV is defined as follows. record(ai, "$(P){$(DEV)}TrajInitPlc-Read") { field(DTYP, "stream") field(INP, "@ppmac_stream.proto getVarInt(Plc[15].Running) $(SSH)") field(SCAN, "0.5 second") } -- getVarInt is defined as follows getVarInt{ out "\$1"; in "\n\$1=%d"; } -- Port configuration is as follows drvAsynPowerPMACPortConfigure("SSH1", "10.7.130.93", "root", "deltatau", "0", "0", "0") Thank you, Chanaka De Silva NSLSII
