Remote Monitoring Calculates Machine Run Time [Success Story]
Accurate machine run time data is collected and logged at a control location
Customer Requirements: Accurate machine run time data was needed to determine why production goals were not being met
Solution: DX80G9M6S-PM8 Gateway, DX80N9X6S- PM8L Node
Why Banner? Long-range bidirectional wireless system supports six discrete inputs and six discrete outputs for each Node
Customer Benefits
Improved Performance – Accurate machine run time information allowed the customer to manage the machine downtime
Background
During normal operation, operators load a welding machine with the frame components to be welded. The loaded parts enter a robot welding cell and a completed frame exits. The operators unload the completed frame and load more components in preparation for the next welding cycle.
Challenges
Production goals were not being met. Operators blamed machine downtime for the failure to meet production goals and maintenance personnel blamed operators for working too slowly.
To determine where the problem was, this facility needed to accurately measure and report machine run time back to a control location.
Solution
PLC logic added to the welding machine now turns on an output when the allocated process time is exceeded. This output is wired to an input of a PM8 Node. The Node’s input is transmitted back to a PM8 Gateway connected to an HMI that logs overage time. Accumulated overage time is totaled for each shift and operator.
Accurate work time is gathered at the welding machine and wirelessly transmitted back to a central control location for logging without running new data wires.
Based on real-time data collection, the facility managers were able to accurately verify when the delays were the result of machine down time and when the delays were the result of operator inefficiency.
