Test/Startup

Operation/Maintenance

With the system configuration diagram where an entire system can be graphically described and the workspace tree where various projects can be managed in one place, the overall control system can be set at once and projects can be managed easily.

The jump function between programs and the global label shared between multiple PLCs/motion controllers and GOT reduce the number of operations and remove troubles for changing programs.

The functions such as a simulation based on the system configuration diagram created at a design phase, the multiwindow monitoring and the system diagnostic function reduce the time for adjusting the machine linkage section and the time for identifying a place where an error occurs.

Executing a batch read/write linked with the system configuration diagram removes troubles for the system management. In addition, the history management allows you to manage the version of backup data.

Machines such as robots or conveyors are operated by a standard PLC. If an error occurs on the safety PLC, it is detected by the self-diagnosis function and the safety output is forcibly turned off. This safety function differentiates the safety PLC from a standard PLC. * Certified by TUV Rheinland

A PLC station number, CPU number, program name and coil number can also be assigned to a one-touch button. In the circuit block of the coil displayed with the one-touch button, not only the PLC connected to the GOT but also other station PLC, multiple CPUs, multiple CPU programs, and local devices can be specified.

Easier-to-read operating commands greatly reduce operational mistakes!! The operating commands are clearly shown on the GOT's high-intensity, wide-view angle, and large screen. By supporting a multilingual environment, GOTs meet the needs of globalization.

Backing up your important sequence programs - "Backup/Restore functions" prevent data loss

Problems are easily resolved on site without a personal computer!! The error location and countermeasure can be checked on site using the one-touch ladder jump function or document display function of the GOT. With the backup/restore functions, the sequence program can be changed incase of errors.

The data of a PLC CPU such as sequence programs and parameters can be backed up to the CF card of a GOT. Data can be batch-restored (rewritten) to the PLC CPU when necessary. Change the program in a PLC CPU, simply by using the CF card. No personal computer is required at the production site. Usage example 1)

Usage example 2)

By backing up data in advance, replacement or recovery can be quickly performed when the PLC CPU becomes faulty or the battery runs out.

Data such as a sequence program must be exchanged, analyzed or corrected when an error occurs or the program in the PLC CPU is updated. With this function, those tasks can be completed without an experienced engineer, leading to cost and time reductions.

Maintenance costs are reduced by a longer life and life check!!

The degree of deterioration of the main circuit capacitors, control circuit capacitors, and the inrush current limiting circuit can be monitored. Faults can be prevented thanks to the self-diagnosis alarm that is output when a component is nearing the end of its service life.

Consumable parts (capacitors, cooling fans) are designed to last for 10 years. Faults can be avoided with a self-diagnostic alarm that is output when the life of an inverter part is near its end.
