5 Data Backup

The user programs, I/O memories, and other data in the Coordinator Module and Motion Control Modules is backed up either by a super capacitor or flash memory, as listed in the following table.

Module	Data	Data backup
Coordinator Module	Error log	RAM with super
		capacitor
Motion Control Module	DM Area words D30000 to D32767
	Error log
Coordinator Module	User program	Flash memory
	System Setup
	DM Area words D30000 to D32767
Motion Control Module	User program
	System Setup

The data backup time of the super capacitor is given in the following table and shown in the following graph.

Temperature	Initial	After 5 years	After 10 years
Ta = 25°C	101.61 hours	96.2 hours	90.8 hours
	(4.23 days)	(4.01days)	(3.78 days)
Ta = 40°C	26.39 hours	15.28 hours	4.16 hours
	(1.09 days)

Note	1.	The times give above assume that the capacitor is completely charged.
		Power must be supply to the FQM1 for at least 20 minutes to completely
		charge the capacitor.
	2.	The backup time of the super capacitor is reduced as the capacitor ages.
		It is also affected by the ambient temperature. Use portion of the DM Area
		backed up by the super capacitor only for data that is to be held during mo-
