We have implemented PI server in our company for Information management
In our system total 5 interfaces are connected and working. Three interfaces
are OPC, other two are modbusE.
Network description: - One OPC interface is connected via copper network. And
remaining 4 are connected using wireless network.
From all wireless networked interface i have face frequent problem.
Mostly ModbusE interfaces are stop working frequently wiht UTC time Offset.
my checkpoints are as below.
01:- I have check Time zone of server and interface machint and both are
02:- I have set time of server and clint same to same.
03:- I have set PLC time and date same as interface machine and server.
04:- I have check buffering system of my interface. API buffering is
05:- Three scan class are defined, 02 second, 03 second and 05 second.
For OPC interface worked on same wireless network i face same problem but frequency
of failure is very low (ones in month)
What is probable solution for solve this problem.
