OFS Server Preloading on build changes program

[Anonymous user]

I am using OFS OPC server for communication with M580 PLC. Now Problem is while build changes in program data this OPC server stopped and preloading. during this process hmi get disconnected from PLC. Please suggest the required changes in configuration if i want uninterrupted communication at HMI. I am using data dictionary and HMI variable only for the tags.

It is worth checking the settings in the OFS alias used for each PLC.  

1. use the latest OFS current version is 3.63.4902
2. In the PLC embedded data settings make sure the following are checked:  
   • Use data dictionary
   • No communication break

At the PLC end under the project settings \ embedded data settings:

1. if needed you can adjust the effective build changes time-out starting at 40 if the size of the data dictionary is quite small you can reduce the size which can make the update process quicker.
2. preload on build changes may also improve the process.

Hope this helps.
