Bus communication

CS-L2 bridge

The inputs and outputs are electrically isolated. The module electronics (ASIC) is protected against overvoltages by appro- priate circuitry measures.

The digital inputs comprise 8 channels organized in groups of 4 x 2 channels. The current consumption is 8.5 mA with an input level of DC 24 V.

An input delay of 500 ms or 3 ms can be parameterized for all input channels together.

The cable length is:

• unshielded 200 m (for 500 ms) or 600 m (for 3 ms)

• shielded 1000 m.

The digital outputs also comprise 2 x 4 channels. With DC 24 V, the max. output current is 100 mA. The outputs are protected against short-circuit by an electronic fuse.

A 25-contact Sub-D socket is used as the interface.

■Overview

CPU 486-3

The CPU 486-3 is equipped with an Intel Pentium 75-MHz pro- cessor.

The front panel of the rugged, compact plastic housing contains:

IF 962-COM serial interface module

The IF 962-COM serial interface module is required to connect a commissioning terminal to the CS-L2 bridge. The module is in- serted into a prepared slot in the CPU 486-3.

•LEDs for status and fault display

•Operating mode switch

•Slot for a memory card from which the coupling software and bus parameters are loaded into the main memory when start- ing up

•2 slots for interface modules

■Design

Memory module (set with 2 x 8 Mbyte)

The CPU 486-3 used in the CS-L2 bridge is supplied with an integral RAM. The module used as the main memory comprises a set with 2 x 8-Mbyte RAMs. The complete set must always be inserted.

I & C monitoring

I & C monitoring functions can be implemented using the IF 961-DIO interface module for digital input/output.

The interface module is inserted in the EXM 478-3 module of the AS 488 automation system.

The IF 961-DIO can be used to record I & C signals e.g. for

•door contact

•excess temperature

•monitoring of optical link module OLM

and to activate a cabinet lamp or horn.

Cable monitoring, e.g. to detect an open-circuit, is not possible.
