You can use the Server Configuration Tool’s Channel settings to define the Maximum Number of Consecutive Read Timeouts and the Maximum Number of Write Timeouts. These settings provide a limit for consecutive timeouts or late replies from a remote outstation.

To set appropriate Maximum Number of Consecutive Read Timeouts and Maximum Number of Write Timeouts for your system, you need to have an understanding of:
- How Geo SCADA Expert Uses the Consecutive Read and Write Timeouts

This means that you may need to compromise when applying your limits, as you will need to consider the overall effects of the limits, not just how they affect one particular driver or channel.
