Initialization - Siemens MPP 464 IE H Equipment Manual

Initialization

LEDs on the control panel
• HF1 to HF25
• HS1 to HS4
• HS7 to HS10
Switching on the MPP 464 IE H (POWER ON) also switches on all the LEDs on the control panel
which then remain permanently lit.
Once internal power-up is completed, the LEDs blink at approx. 1 Hz until communication is
established with the control or another client ("Waiting for Client").
LEDs on the COM board
The LEDs on the COM board of the MPP 464 IE H (rear) are not controlled by the software. They
are used exclusively to signal the hardware states, e.g. "Power supply OK".
Software version
If there is no communication with the controller yet, the software version of the MPP 464 IE H
can be output on the panel via the LEDs.
The output is activated by pressing the "F21" and "F25" buttons at the same time. Flashing of the
LEDs is thereby suppressed and the software version is output on the function key block with
three digits.
The individual digits are expressed in hexadecimal format by the number of LEDs activated in the
first three LED rows on the MPP.
The least significant bit position is on the right in each case.
The software version of the MPP V 02.01.00.00 is shown in the following example.
