Switch on behaviour After switching on the supply voltage the CPU performs a system self test If the test has been completed successfully the runtime system starts The red and green LED flashes if there is a malfunction After the start of the runtime system the CPU checks if an operating system update is available on the inserted MMC and also if this must be loaded As the PLC does not feature a battery for backup of the main SRAM memory after the start of the runtime system it checks if a boot project is available If this is the case it is loaded in the main SRAM memory and starts Power on No dependent on the position of the operating mode selection switch and the set start behaviour If the flash memory contains no boot project the PLC remains in NOT READY state Switch on behaviour with boot project When the PLC is started a boot project available on the MMC has priority over a project stored in the system memory Flash If the boot projects are different the boot project from the MMC is copied into the system memory Flash and then run Due to the copy process the PLC start up phase will be extended by a few seconds Boot project on MMC Boot project in the system memory Flash Boot project on MMC Boot project in system memory Flash Y Y Boot project in the No system memory Flash Load boot project from system memory Flash into the main memory and
