I have some problems with OPCInt UFO - Failover.
I have 5 OPCInt's installed on two machines (OPC Client Main and OPC Client reserve). On different machine I have OPC server. Normally everything is working properly - there is no data loss. Since I have run failover on this interfaces i realize that there is a problem with sync files. In log I get info:
OPCpi> 16> WARNING> Failover Warning: Errror = 71
Unable to open Failover Control File '\\172.17.83.135\SharedFiles2\OPCInt_O_78.dat'
OPCpi> 16> INFO> the interface successfully opened the failover sync file.
There is many identical entries for all 5 OPCInt's and it happens many times per hour.
Sync files are stored on different machine in the same network.
Interfaces are installed on two separate machines, opc server is different machine, sync files are located on different machine.
Same network, workgroup and user accounts. Data is collecting properly - no losses.
OPCInt version: 188.8.131.52
Uniint version: 184.108.40.206
Windows XP on all machines.
Sync files located on windows shares, public with 'everyone' full access. Different shares for different interfaces.
Where is the problem?
What does error 71 mean?
