Dispatcher

The Dispatcher is a critical component of the Execution Scheduler system responsible for receiving incoming tasks, determining their priority and resource requirements, and assigning them to the appropriate execution units or workers. It acts as the central coordination point to ensure efficient workflow, load balancing, and timely processing within manufacturing or automated systems. The Dispatcher continuously monitors a task queue and evaluates predefined rules, such as priority, resource availability, and dependencies, to make routing decisions. It then sends tasks to selected execution units and may track their status until completion, facilitating communication between the scheduler and the executors. This component is typically housed in a plastic or metal enclosure and contains electronic components mounted on a printed circuit board (PCB). It supports various communication interfaces, including Ethernet, RS-485, and CAN, and operates within specified environmental and electrical parameters. For instance, it can handle 100 to 1000 tasks per second, with scheduling latency between 1 and 10 ms and precision of ±0.1 ms. It operates in temperatures from -40 to 85 °C and can be stored from -40 to 105 °C, with relative humidity up to 95% non-condensing. The supply voltage is 24 V DC ±10%, and power consumption ranges from 5 to 15 W. The ingress protection rating varies from IP20 to IP65, and the device weighs between 0.5 and 2.0 kg, with dimensions ranging from 100×75×30 mm to 200×150×60 mm. These values are reference ranges and must be verified for the specific model and application. The Dispatcher is designed for DIN rail mounting and is suitable for use in industrial environments. It is important to confirm model-specific parameters and compliance with relevant standards, such as IEC 60068-2-1 (cold-test reference; it does not establish the listed operating-temperature range), IEC 60068-2-2 (dry-heat test reference; it does not establish the listed storage-temperature range), IEC 60068-2-78, IEC 61131-2, and IEC 60529, with the legal manufacturer or supplier.

The Dispatcher operates by continuously monitoring a task queue. Upon receiving a task, it evaluates predefined rules (such as priority, resource availability, and dependencies) to make a routing decision. It then sends the task to the selected execution unit and may track its status until completion, facilitating communication between the scheduler and the executors.
