Sequence logic control

The Sequence Logic Control section of the PLC is responsible for the actual control and monitoring of each individual machine movement/action within the step sequence. This area is divided into "Sequence Zones." A "Sequence Zone" is responsible for controlling and monitoring a single action (e.g., motor on). Therefore, each step of a sequence can contain one or more 'Sequence Zones.' Under the influence of the step counter, the "Sequence Zone" sets the relevant real-world outputs and monitors the corresponding real-world inputs that are associated with the respective movement or action.
