SY-TRANS 300 CS gateway
Description

Application
The
Design
The gateway comprises the basic hardware and a software component which handles the communication server function in the computers connected to the LAN.
The basic device contains
an interface module for the Ethernet bus.
A power supply unit is used for DC 24 V oder AC 115 to 230 V.
The system software is present as firmware in EPROMs and need not be loaded. The software is different depending on the required network protocols.
As a result of the housing depth, the basic device can only be installed hanging vertically with the front panel upwards in TELEPERM M standard cabinets (also those with depth of 600 mm).
Connections
The CS 275 interface is connected via a cable for
The SINEC H1 interface is connected via a
The Ethernet interface with TCP/IP or DECnet is available via a BNC plug and also via a
The
The software component is a communications server (client/ser- ver architecture) with a simple communication interface to the user: the library OPEN CS. This contains command procedures and library routines and can be executed in the computer under one of the following operating system platforms:
VMS, OPEN VMS, ULTRIX, OSF/1, UIX, SUN OS, SINIX, SCO UNIX,
The network protocols TCP/IP, DECnet or SINEC H1 (ISO trans- port) can be used in the LAN.
User applications in the computer can be readily linked to auto- mation systems of the TELEPERM M process control system using simple library calls. The following AS automation systems can be communications partners: AS 230 2), AS 230 K 2), AS 235, AS 235 K und AS 235 H.
Library calls are offered as standard for the following CS 275 functions:
The library OPEN CS can also be extended by further CS 275 functions for specific projects.
Further functions have already been implemented which permit the design of a
1)AUI = Attachment Unit Interface.
2)These automation systems are no longer available.
