Scb1 As Master For Sci1 And Sci2 - Siemens Simovert 6SE70 Series Operating Instructions Manual

Start-Up
Switching off and on of the electronics supply voltage. Doing this causes the values of the parameters
4
listed above to be transferred from the supplementary board.
The optional board SCB1 (Serial Communication Board 1) is used
- as Master of SCI1 and SCI2 slaves ( S erial C ommunication I nterface).
- for communication via the peer-to-peer interface.
In both cases, communication between the boards takes place via fiber optic cables (recommended:
Siemens plastic fiber optic cable, CA-1V2YP980/1000,200A or Siemens fiber optic cable with glass core,
CLY-1V01S200/230,10A)

SCB1 as master for SCI1 and SCI2

The SCI boards can be used if additional terminals are required or if safe electrical isolation via fiber optic cable
is a mandatory requirement.
This board only allows the SCB1 master to exchange data with the SCI slaves. Data cannot be exchanged
between the SCI slaves themselves.
A maximum of 2 SCIs, of either the same or different types, can be connected to the SCB1.
SCI1 or SCI2 are terminal expansion boards which are mounted on a rail outside the SIMOVERT 6SE70 master
and supplied with 24 V DC voltage (-17% +25%, 1A) from an external source.
The interface boards extend the converter by the following additional inputs/outputs:
SCI1
10 binary inputs
8 binary outputs
3 analog inputs
3 analog outputs
Reception of SCI data by the SCB1 or transmission to the SCIs is synchronized, i.e. the data of two slaves is
received simultaneously or transmitted simultaneously.
Details of the input/output functions and connections can be found in the operating instructions for the
SCI boards have no external enclosure to protect them against direct contact or ingress of
pollutants. To protect them against damage, they must be installed in a housing or in the
control cabinet of a higher-level system.
The maximum permissible length of fiber optic cables is 10m.
An input filter must be fitted for the external power supply of the interface boards.
Ground SCI at X80 using a short lead.
Analog inputs on SCI1: Only the voltage input or the current input may be used for each
channel.
Analog outputs on SCI1: Only the voltage input or the current input may be used for each
channel. The outputs are short-circuit-proof.
The binary driver outputs are short-circuit-proof. Relays may only be connected to these
outputs in conjunction with an external power supply.
The binary relay outputs are not designed for protective separation.
To protect them against static discharge, the boards may only be placed on conductive
surfaces.
