Connecting 1PPS time sync interface
Depending on the application, a SAM600 system can be setup to run as a free-running system
or require an external 1PPS signal from a time master or another merging unit. If an external
1PPS synchronization is required, use port X300 on SAM600-TS to connect a 1PPS signal.
SAM600-TS provides five 1PPS outputs, which can be used to synchronize bay level protection
and control devices, or 3rd party merging units, such as the ABB FOCS. The connectors X301-
X305 on SAM600-TS provide a synchronized 1PPS output signal.
PPS output connectors X301-X305 meet Class I Laser safety requirements per
IEC-60825-1 standard. Do not stare into the beam or view the beam directly
with optical instruments. Failure to observe this warning could result in an eye
injury or blindness.
Connecting the configuration interface
Use a USBA-A cable on port X105 in order to establish a communication to a PC with PCM600.
For setting up PCM600 and appropriate drivers for communicating with SAM600 modules, see
SAM600 engineering manual (1MRK 511 433-UEN).
Connecting the SAM600 system bus
SAM600 modules can be combined into a SAM600 system by connecting the modules in a
daisy chain or ring. The communication link between SAM600 modules is called SAM600
system bus.
Each SAM600 module has two pairs of electrical and optical communication ports (X103/X104
and X101/X102 if equipped with LC SFP modules). A SAM600 module can interface to the
SAM600 system bus with any two of these communication ports. Edge modules in a daisy
chain SAM600 System bus can use one more port as access point to the process bus.
It is recommended to use an electrical communication port for connecting to a neighboring
SAM600 module deployed in the same marshalling kiosk. For a communication connection
that leaves the kiosk an optical communication port should be selected.
The ports X106 and X107 on SAM600-TS modules cannot interface to the
SAM600 system bus. These two ports can only interface to the process bus.
Connecting process bus communication interfaces
Optical communication is typically used for IEC 61850 process bus communication. For a
SAM600 system, ports for IEC 61850 communication are defined in PCM600.
Depending on the layout and deployment of SAM600 modules, the number of SAM600
modules in a system results in a scalable number of communication ports that are available
and can be used for IEC 61850 process bus communication.
On SAM600-TS modules two communication ports can be joined into an access point with
communication redundancy according to PRP or HSR standard (IEC 62439-3:2016). It is allowed
to combine any two of the SAM600-TS module’s communication ports into a redundant access
point.
Configuration of access points is done in the System Configuration Tool in PCM600.
Use the approved SFP module and fiber optic cables with LC connectors in order to establish a
communication connection with bay level protection and control devices.
