Hi Robert / Claes,
I would appreciate your help to configure the XML-DA communication in Proview:
OPC server : the OPC_server Config object is placed below the node 'acdesktop'.
Port : 8080
OPC Client Access : the IP address of OPC client and Read access.
The status monitor shows : opc_server - Server running
OPC Client : extern volume is created using the GlobalVolumeList : 'MyOPCVolume' , Vol Id : 0.1.99.55
Mount object is created in the plant hierarchy with objid _O0.1.99.55:0
Additionally the appl. file with 'ld_appl_acpc_508.txt' has been added to $pwrp_load. The file contains the lines:
opc_provider, opc_provider, noload, run, opc_provider, 9, nodebug,
http://acdesktop:8080 0.1.99.55 MyOpcVolume
(acpc and 508 are the name of client node and qcom bus no. respectively)
The terminal window on the client side shows the following :
I Starting opc_provider, file: opc_provider, prio: 9
I Started opc_provider, prio: 9, pid: 6973
file: opc_provider
sched_setscheduler: Operation not permitted
failed to set pid 6973's policy
remote_pvd_pwrcli Proview provider client
Arguments:
1 Opc server URL
2 Extern volume id
3 Extern volume name
4 Server identity (optional, default 200)
I Process pwr_linksup_508 exited with status 0
I Process pwr_remh_508 exited with status 256
java.library.path = /lib/i386/client:/lib/i386:/../lib/i386:/usr/pwr45/os_linux/hw_x86/exp/exe
I Process pwr_elog_508 exited with status 256
MaxNoOfAlarms: Nodes-acpc-WebHandler-User 0 false
I Process opc_server_508 exited with status 8704
I Process opc_provider exited with status 0
What is wrong in the configuration?
I also tried to use an OPC XML-DA client tool, but it is not possible to browse any items. It seems that I am not using the right syntax. If the item is Lvalue in the tree DEMO-Modbus-Signal-Lvalue and float datatype.
How is the syntax to access the data?.
Many thanks in advance.
Valdemar
