Visual KV series
Monitor Operation and Make Changes Without a PC
The Visual KV CPU features a built-in display (Access Window) that allows the PLC's data to be checked upon start-up, as well as during modifications or changeovers. Using the Access Window, a PC or handheld programmer is not required to monitor operation or perform minor changes to the program.
When checking or changing some device values, the PLC does not need to be connected to either a PC or handheld programmer.
Precise on-line adjustments to internal devices, such as a timer, can be made while the PLC is operating.
The user can stop the PLC and check the program without connecting to a PC or handheld programmer.
The Visual KV features a key lock function to prevent accidental changes to the settings
Error codes are immediately displayed on the LCD. With a conventional PLC, the PLC has to be connected to a handheld programmer in order to determine the error code.
With a simple ladder program, a flashing LED display message (No.0 to 255) can appear, indicating a user error code.
