Maintenance

10.1 In this Chapter

Maintenance = operating system back-up/update, replacement of modules and
fuses
S7-300 is a maintenance-free automation system.
Thus, by maintenance we mean
• backing up the operating system to a memory card (MC) or micro memory card
(MMC). The use of an MC or MMC as the storage medium depends on the type
of CPU used.
• Operating system update from MC or MMC
• Replacement of modules
• Replacement of back-up battery/rechargeable battery (only for a CPU with MC)
• Replacement of the fuses in digital output modules
In this chapter
we show you how to back-up or update your operating system and to replace
modules, the back-up/rechargeable battery and the 120/230 VAC fuse of the digital
output module.
