The Driver Command task executes lifecycle commands that control the state and operation of a driver.
It provides explicit control over when the driver connects, disconnects, or retries a connection.

Behavior#
The Driver Command task manages the driver’s operational state by executing lifecycle commands.
It is used after configuration and event initialization to establish or control communication with the equipment.
A typical workflow using this task includes the following steps:
- Driver Event detects a lifecycle event (such as
OnInitialize). - Equipment Configuration defines the driver’s parameters and setup timeouts.
- Driver Command issues the appropriate lifecycle command (for example,
Connect) to start driver communication.
