SCom/SCB TlgOFF
Telegram OFF time of CUR and SCB
If no correct telegram is received within the parameterized time a fault trip is
set.
Description for setting:
Value 0: No monitoring, no fault trip; must be parameterized for sporadic
(acyclic) telegrams, e. g. operator panel OP at serial comm. interface 1.
i001 = SST1: serial comm. interface 1 (CUR)
i002 = SCB: SCB, if P682=1, 2, 3
i003 = SST2: serial comm. interface 2 (CUR with PTP1 option), if
Peer-to-Peer protocol is selected (P688=1).
With active Peer-To-Peer protocol (P688 = 1) and telegram
failure time P687.i003 ≠ 0, the unit remains in operating state
o
008 until telegram traffic is correct
(see P688).
With P687.i003 = 0
AND P681.i001 = 599 in the case of
telegram failure
, bits 3 and 6 of the first SST2 Peer-to-Peer
receive data (the control/status word sent from the partner unit
in 12-pulse mode) are set to 0.

SST2 Protocol
Selection of the protocol for SST2 (serial interface 2 (CUR with PTP1
option))
0 Interface is provided for factory-internal diagnostics purposes (7
data bits + 1 parity bit, even parity,1 stop bit)
1 Peer-to-Peer protocol
(8 data bits + 1 parity bit, even parity,1 stop bit)
With active Peer-To-Peer protocol (P688 = 1) and telegram
failure time P687.i003 ≠ 0, the unit remains in operating state
o
008 until telegram traffic is correct.

P689 SCB Peer2PeerExt
Immediate transfer on of data received via the peer to peer protocol of SCB.
Mark of these words of the received peer to peer telegram which are to be
transferred on immediately.
0: No immediate transfer (only to CUR)
1: Immediate transfer (and passing to CUR)
i001 = W01: Word 01 of the (process data part of the) telegram
i002 = W02: Word 02 of the (process data part of the) telegram
. . . . .
i005 = W05: Word 05 of the (process data part of the) telegram
Condition: P682 = 3 (peer to peer protocol)

SCB Act Values
Actual value output via the serial communications interface of the SCB
board.
Defines, which parameter is to be transferred at which telegram address.
Notes:
Word 1 should be set for status word 1 (r552=r968)
The length (number of words) of the process data part of the telegram is set
with P686, Index 02
