Production Monitor Another application for event loggers is for production monitoring. It is an effective tool in the hands of management. Management can observe when a particular machine was switched on, when it was idle, when there was no power. Information about run time, idle time etc can be derived from the logs in the event logger. In the simplest form the event logger can generate a report of at what time a particular system was switched on and at what time it was switched off. Typical report can be
Number of such units can be networked on an RS485 bus and connected to PC. Ajinkya provides Production monitoring software which can upload data from these units and generate shift wise reports. |
