Hi All, We have an issue with trying to get multiple poll groups talking to a Siemens S7 PLC using s7nodave: According to the documentation (http://oss.aquenos.com/epics/s7nodave/docs/1.0.0/manual.html), it should possible to specify a pollgroup using the PG parameter: "In order to make a record be processed in a poll group, the SCAN field of the record has to be set to I/O Intr . If you want to use a different poll group than the default poll-group, you can use the PG parameter to specify the poll group to use. The PG parameter can be used with all input records to specify a poll group for the record. It is only valid, if the SCAN field of the record is set to I/O Intr . Example: @myPLC(PG=1s) IW64" But I get this error: 2015/10/15 17:50:14.252 HJ_CRYO:PID_TEMP_KP S7nodaveRecord::initRecord Invalid device parameter "PG" in device address "@HJ_CRYO(PG=fast) DB100.DBD236 float". HjCryo: //usr/local/epics/support/boost_1_57_0/boost/optional/optional.hpp:1002: boost::optional<T>::pointer_type boost::optional<T>::operator->() [with T = S7nodaveRecordAddress, boost::optional<T>::pointer_type s7nodaveRecordAddress*]: Assertion `this->is_initialized()' failed. $Aborted (core dumped) Anyone encountered this before? s7nodave version is 1.0.2 and st.cmd config and record are as follows: s7nodaveConfigureIsoTcpPort("HJ_CRYO","192.168.43.28",0) s7nodaveConfigurePollGroup("HJ_CRYO","default",5,0) s7nodaveConfigurePollGroup("HJ_CRYO","fast",1,0) record(ai, "$(DEVICE):PID_TEMP_KP") { field(SCAN, "I/O Intr") field(DTYP, "s7nodave") field(INP, "@HJ_CRYO(PG=fast) DB100.DBD236 float") field(EGU, "") field(PREC, "2") } Thanks, David
