Standard upgrade

PCMCIA card
name convention
12-288
The PCMCIA cards used for the NCU and MMC have the same external ap-
pearance and are therefore occasionally difficult to distinguish. We will distin-
guish between them below by referring to the PCMCIA card
S
for the NCU as "NC card" and
S
for the MMC as "PC card".
Every SW package is supplied with a read me file in the tool box. This file de-
scribes how to upgrade the control software with the new version.
S
Save all control and user data before you commence with updating (see
Section 11 Data backup).
S
Switch off the control.
S
Insert the NC card with the new firmware into the PCMCIA slot.
Proceed as follows:
1. Set switch S3 to 1.
2. Switch on power.
3. During power-up, the firmware is transferred from the NC card to the device.
4. Wait until the digit "6" appears on the display (this can take up to 2 minutes).
5. Set switch S3 to 0.
6. Perform a PLC general reset: Switch S4 to "2", then to position "3". Within
3 seconds, turn the switch to positions ("2"–"3"–"2"). When the PS and PF
LEDs light up, switch S4 to "0" (see Section 5.2).
7. Then proceed as described in Section 11.2 (series start-up), to restore the
back-up data. Please note any manufacturer instructions regarding the new
software version.
Note
If the display does not get as far as "6" the possible causes of the error are:
– Software and hardware mismatch (e.g. PC card NC with software for
NCU 572.2 is plugged into an NCU 573.2)
– Defective NC card or hardware
