S7 – 300
MRES = Memory reset function
STOP = Stop mode, program not executed
RUN =

Program execution
RUNP = Program execution, read/write access

SF = Group error, internal CPU or fault in module
BATF = Battery fault
DC5V = Internal 5 VDC voltage indicator
FRCE = FORCE
RUN = Flashes when the CPU is starting up,
then steady light in Run mode
STOP = Show steady light in Stop mode
SF DP = Physical bus fault
BUSF = No configuration or incorrect configuration

Mode Selector

Status Indicator

BYTE
WORD
For a unit of 8 binary characters,

the term BYTE is used. A byte has the size of 8 bits.

A word also has the size of 2 bytes or 16 bits.

A double-word corresponds to the word length of 32 binary characters.
A double-word also has the size of 2 words, 4 bytes, or 32 bits.
