Chapter 17 Using the Memory Module
Backup and restore can only occur when the Cat. No. 2080-MEMBAK-RTC
module is present in plug-in Slot 1 (the leftmost slot) of the Guardmaster 440C
safety relay. On safety relay power-up, the safety relay enters a fault state where
the application logic is not executing. Backup and restore commands can be
issued in this fault state.
The Cat. No. 2080-MEMBAK-RTC memory module stores the safety relay
password, if present, in encrypted format. When the password is mismatched, the
contents of the Cat. No. 2080-MEMBAK-RTC memory module is not restored
on the safety relay.
Back-up Project
You can back up a Guardmaster 440C safety relay project to a Cat. No.
2080­MEMBAK-RTC memory module using the button on the memory
module.
1. Power down the Guardmaster 440C safety relay.
2. Remove the dustcover or plug-in module that is currently located in slot 1,
the leftmost slot, of the safety relay module bay.
3. Snap the Cat. No. 2080-MEMBAK-RTC module into slot 1 of the
module bay.
4. Power on the Guardmaster 440C safety relay.
The safety relay detects the presence of the Cat. No. 2080-MEMBAK-
RTC memory module and enters a fault state
The behavior of the IN and OUT LEDs depends on whether the
configuration is verified:
• Verified
- the IN and OUT LEDs continuously cycle through the
verification number.
• Not Verified - the IN 0 and the OUT 1, 2, 3 and 4 are solid green. The
backup cannot take place since the configuration is not verified.
The LEDs are as follows:
PWR - solid green
RUN - off (not executing)
FAULT - solid red
LOCK - solid green
COM - off
