Changing the Display Status ± DISPLAY Button

You can change between the status display (basic status), slave display and PROFIBUS display with the DISPLAY button. Each time you press the button, you change to the next display status finally returning to the initial status.

In the slave display, the slaves on the AS-Interface are displayed in groups of 5 slaves. You can move on the display to the next group with the DISPLAY button. First the standard or A slaves are displayed and then the B slaves (ªBº LED is lit).

You return to the status display as follows:

SAfter you have displayed the last group (slave 30B, 31B) by pressing the DISPLAY button or

SIf you do not press the DISPLAY button for a longer period of time (approximately 8 minutes).

Meaning of the LEDs

The front panel of the CP 243-2 has two rows of LEDs.

SThe LEDs CM, AUP, CER, APF, PWR and SF in the upper row represent the status display.

The B LED indicates B slaves. It is lit when the slave display is active if B slaves are displayed.

SThe first five LEDs of the lower row indicate the connected slaves (slave display).

The other three LEDs indicate the slave group.

The meaning of the LEDs depends on the status of the group displays.

If all the LEDs of the group display are off, the status display is active; in other words, the LEDs CM, AUP, CER, APF, PWR and SF indicate the status of the CP 243-2.

If at least one of the LEDs of the group display is lit, the status display goes off (exception: ªPWRº LED remains lit) and the slave display is active.

SET Button

The SET button is required to configure the CP 243-2.
