6.5.8.1 Programmable Controller Testing

The process control system is typically an active system where problems, should they occur, will come to the attention of the operator through process deviation from expected operation. This reduces the need for process control system testing but there will still be times when additional testing will be required. These are:

After upgrading the operating software of the controller

After changes to the communications or network configuration

After hardware upgrades or replacement

When recommended by the manufacturer
