7-Segment LED Display
A two-digit 7-segment LED display makes it easy to monitor PLC status. This
improves the human-machine interface for maintenance, making it easier to
detect troubles that may occur during machine operation. The items indicated
below can be displayed.
Contents of Display
The following items can be displayed in the 7-segment LED.
• Unit version (only when the power supply is ON)
• Error codes for errors that occur during CPU Unit operation
• Progress of transfers between the CPU Unit and Memory Cassette
• Changes in values when using the analog adjuster
• User-defined codes from special display instructions in the ladder pro-
gram
Unit Version Display
The CPU Unit version is displayed for approximately 1 s when the power sup-
ply is turned ON.
CPU Unit Error Display
When an error occurs at the CPU Unit, the error code is displayed. If multiple
errors occur simultaneously, they are prioritized for display in order of impor-
tance. Then, as each error is cleared, the error code for the next one is dis-
played.
For details, refer to 9-1 Error Classification and Confirmation.
