RUN/STOP button
The processor modules, PM50xx series, have a RUN/STOP button. By pressing the RUN/STOP button, the processor modules switch between RUN mode and STOP mode. By long-pressing RUN/STOP button during the processor module power on phase, the processor module will be in MOD1.
State LEDs
The processor modules PM50xx indicate their states of operation via 5 LEDs located on the upper left side of the processor module.

Micro memory card indication |
Yellow |
Micro memory card is in the socket |
Micro memory card is not in the socket |
Micro memory card is in read/write state: any file on card is opened, means activity on card |
|
ERR |
Error indication |
Red |
An error occurred |
No errors or only warnings encountered (E4 errors). The LED behavior for the error classes 2 to 4 is configurable. |
Fast flashing (4 Hz) displays together with the RUN LED a currently running firmware-upgrade or writing data to the flash EPROM. Slow flashing (1 Hz) alone displays shutdown of Request To Send. Medium flashing (2 Hz) alone displays at start of PLC if reboot after watchdog. |

MOD1 |
Mode 1 indication |
Yellow |
Processor module is in mode 1 state |
Processor module is not in mode 1 state |

RUN |
RUN/STOP state |
Green |
Processor module is in state RUN |
Processor module is in state STOP |
Fast flashing (4 Hz): The processor module is reading/writing data from/to the memory card. If the ERR-LED is also flashing, data is being written to the flash EPROM. |
|
Slow flashing (1 Hz): The firmware update from the memory card has been completed successfully or Boot project is being updated. Slow flashing (0.5 Hz) together with MOD1 LED ON: Mode1: Boot project is not loaded. |

Additional two LEDs are reserved and can be controlled from IEC user code with FB PmLedSet |
User configurable LEDs
The processor module also provides 2 LEDs below the state LEDs which can be used by user and driven by an application.
The LEDs can be used into a project and controlled using special function blocks which are contained in the PM library. The POU is PmLedSet located in folder LED control.
I/O LEDs
The processor module provides up to 10 LEDs (PM5012-x-ETH), 20 LEDs (PM5032-R-ETH, PM5052-R-ETH), or 22 LEDs (PM5032-T-ETH, PM5052-T-ETH, PM5072-T-2ETH(W), PM5082-T-2ETH, PM5092-T-2ETH) to display the states of the inputs and outputs.
