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

BYTE
For a unit of 8 binary characters, the term BYTE is used. A byte has the size of 8 bits.
WORD
A word also has the size of 2 bytes or 16 bits.
DOUBLE-WORD
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.
