The Loading tab shows how much load each PointeControl task is putting on the
controller’s processor. Each task’s load is expressed as a percentage of the
processor’s total available resources:
Chart/Ladder execution is the load to process the Flow Charts and
Ladder Diagrams that make up the currently running project.
Debug interface is the load to interface with the Monitor’s debugging
tools .
Local I/O scanning is the load to scan and update the I/O modules and
operator panel specifically in the attached controller.
RTU scanning is the load to scan the I/O points on any additional Remote
Terminal Units (RTUs) that are attached to the controller using the
OptiLogic UDP/IP protocol.
Modbus TCP driver is the load to maintain the controller’s built-in
Modbus TCP driver, if enabled, and to respond to incoming Modbus
requests.
Modbus RTU driver is the load to run the controller’s built-in Modbus
RTU driver, if enabled, and to respond to incoming Modbus requests.
Data access server is the load to maintain communications between the
controller and the Monitor. This includes support for tag browsing,
controller log, performance metrics, and network discovery.
