Non-volatile system
With the SIMOTION C230-2, the SIMOTION Kernel is stored as non-volatile data in a flash
memory. A C230-2 can therefore also ramp up without a memory card.
MMC memory card
The MMC contains the following data:
● SIMOTION Kernel
● Technology packages (TP)
● User data (programs, configuration data, parameterizations, task configuration)
● IP parameters (IP address, subnet mask, router address)
● DP parameters (DP addresses, baud rate)
