Scheduling Modbus database backups and cleanups - Modbus 4.1

Modbus Plugin Guide 4.1

Modbus 4.1

It is important to protect your data by scheduling regular database back ups. In addition, regularly clean your database to remove old data so that the database does not grow beyond its capacity. If the database is full it can cause your integration to stop working.

Before you begin

Ensure you have the following privileges:

What you should know

  • The Directory database stores the plugin configuration, the related entity types, and the blacklist.
  • The plugin role database stores the events and the entity configuration.
  • The plugin role database contains plugin properties, related entities, events, and alarms associated with Modbus.
  • It is a best practice to schedule all database maintenance during non-peak hours.


  1. From the Config Tool home page, open the Plugins task.
  2. Select the Modbus plugin role from the entity browser and click the Resources tab.
  3. Click Cleanup (), choose how long to keep events and when to delete old data, and then click OK.
  4. Click Backup/Restore (), choose the location for backup files, enable automatic backups at least once per week, and then click OK.
