SS52: 6DD1688-0AE2
3. Description
The SS52 board is an interface board for the SINEC L2 DP PROFIBUS protocol. It is inserted into one of the
three slots of the CS7 subrack, corresponding to the actual configuration. A maximum of three modules can be
inserted in each support board.
The interface module has a serial RS485 interface conforming to the PROFIBUS Standard. This interface is
floating (electrically isolated). The interface is physically located at the 9-pin sub-D socket connector X5.
The connection to the support board is established via the CS7-SS4/SS5 /1/parallel interface at the 48-pin plug
connector X1. In addition to the data-, address- and control bus, this connection is also used to connect the, +5
V, +15 V and -15V module power supply. Data transfer with the processor boards is realized via a 16-kbyte
dual port RAM, which is located on the support board.
A double test socket and a double LED, assigned to each slot, are provided on the support board.
The LEDs have the following function:
bright/dark/

flashing
In addition to the reset function by the power supply, a local reset can be initiated by short-circuiting
(jumpering) the two test sockets at the processor of the appropriate interface module This function has no
effect on the remaining subrack. It is required for the software test and fault finding. During normal operation it
is not permissible to initiate a reset using these sockets.
