Store mechanical part serial numbers and process information collected from each process in a database server.Realize traceability by linking the engine assembly information and mechanical part information collected by the MES Interface module in a database.

Link product serial numbers to various data, which allows not only tracking back of each product production process but also data utilization for various purposes.

Key Point

• Link data collected by the MES Interface module and equipment history information of each mechanical part in a database, and utilize the linked data as a single piece of information.

Collect noise during fitting with a high-speed analog input module and perform FFT analysis with a PLC to eliminate quality inconsistencies caused by connector fitting operations that rely on the personnel's sense.

Obtain analog input signals without high-frequency noise components by using a primary delay filter.

Detect incomplete fitting by judging whether the input waveform is within the range of the reference waveform.

Key Points 

• An interface module that captures analog signals from external devices to a PLC (Up to 4 channels in 5 μs.)

• FFT converts time-domain waveforms into frequency-domain waveform.

Perform preventive maintenance of whole equipment by a robot controller collecting signals of operational status and emergency stop alarms from multiple robots, and e-F@ctory starter package analyzing/visualizing the collected data.

Up to eight robots can be connected and monitored on a GOT with the robot monitoring in e-F@ctory starter package.

Key Points 

• Detect errors that were difficult to find with a simple threshold monitoring by using waveform guard band monitoring.

• Easily identify trouble causes by 24-hour operation monitoring and trouble monitoring, leading to reduced downtime.

Reduce cycle time by smoothly switching to torque control during high-speed operation without dropping the speed.

The continuous operation to torque control of the Motion module/Simple Motion module smoothly switches position control to torque control without stopping the motor.

Key Points

• Motion control can be performed with a single controller reducing the size of the control panel.

• A wide variety of motion control such as speed-torque control and positioning control is available.

Monitor operation processes by connecting multiple network cameras to one PLC via a camera recorder unit. Shorten the recovery and cause investigation time by analyzing images and log data of the entire process at an error occurrence.

All device/label data are collected every scan along with timestamps before and after a trouble. Images took by network cameras are recorded.

Key Points

• Set cameras according to the situation of each process with the camera recorder unit that supports various types of cameras.

• Identify the trouble cause by checking and analyzing the images, waveforms, and ladder information of the entire process in a batch.
