Communications Processor CP 541
EWA 4NEB 812 6188-02
Short designation for Standard DIN E 19245, Part 3
Passive station which acts according to Standard DIN E 19245, Part 3.
F
Fieldbus Data Link. Layer 2 of the 7-layer model complying with PROFI-
BUS Standard DIN 19245.
I
The IM 308-C is a DP master for the distributed periphery (I/O) system.
M
The master-slave method is a bus access method with which only one station
is
active and all the others are
passive.
With a message-oriented connection, a message is only transmitted when
required. Initiation takes place via the user program.
P
This is the transfer of slave parameters from the DP master to the DP slave.
Passive stations may only exchange data with an active station when re-
quested to do so by the active station.
The PLC-PLC connection is a direct connection between two programmable
controllers via SINEC L2, without a detour via a master.
Process Field Bus: the German process and field bus standard specified in
the PROFIBUS standard (DIN 19245).
It specifies the functional, electrical and mechanical characteristics for a bit-
serial field bus system.
