DP Base Programming Interface for CP 5613/CP 5614
C79000-G8976-C108-01

Protocol
Rules governing the transmission of data - The rules specify not only the formats of
the messages but also the data flow during data transmission.
Process image
Here: used for a dual-port RAM of the CP 5613/CP 5614 that can be accessed
directly by user programs and where the current data of the slaves are located.
READY time
A PROFIBUS bus parameter- The READY time is the time within which an active
node must be ready to receive an acknowledgment or response after sending a
call.
Reorganization token ring
All the masters on PROFIBUS form a logical token ring. Within this token ring, the
token is passed on from station to station. If the transmission of the token is
incorrect or if a master is removed from the ring, this leads to an error when the
token is passed on (the token is not accepted by this station) and the station is
excluded from the ring. The number of exclusions is counted in the internal
Token_error_counter. If this counter reaches an upper limit value, the logical token
ring is then reorganized.
S7 PLC
Abbreviation for a programmable logic controller belonging to the SIMATIC product
family from Siemens AG.

Semaphore
Wait mechanism for synchronizing several programs, for example in Windows NT.
