HMIs provide transparent link for easier commissioning
18 December 2012
Complex production lines and installations can often see key components located at different ends of a machine, in different rooms, or even on different floors. But in such a decentralised system it is very difficult to debug a PLC program during commissioning or after an upgrade or modification without being able to watch the machinery in operation.
The result is extended debugging time or the need for two or more personnel to coordinate their efforts.
Now, the GOT1000 series of HMIs from Mitsubishi Electric eliminates these problems through a special FA transparent function that enables a PC connected to the HMI to link directly through to other Mitsubishi Electric Automation Systems products, including PLCs, inverters and servo drives.
Wherever these components are on the production line, engineers can form a direct link to them from a PC connected just to the HMI, enabling both the GOT1000 terminal and the PLC program to be debugged in a single, efficient operation.
And because touch panel operation is enabled even when the PC is connected, engineers can see exactly how any modifications to the programs will impact on the machine operation.
This ability to perform debugging locally or over decentralised systems can dramatically shorten downtime, so increasing machine availability.
