Feldbus-Baugruppe 2113 INTERBUS

7.4

7.4.3

7.4-4

EDSIBS-1.0-06/2003

Pos. Element Explanation

1 INTERBUS master with

interface module

The bus system is a master-slave sy s tem, i.e. an INTERBUS master is connected

to several field devices (slaves).

2 INTERBUS loop bus

terminal

The bus terminal connects a long distance bus to a peripheral bus.

3 Remote bus

Fig. 5.4-2 Po s. 3

The following connections are possible with remote buses:

• Connections between INTERBUS master interface module and first bus

terminal or first 2113 fie ldbus module.

• Connection between bus terminal and 2113 f ie ldbus module

• Connection between two 2113 fieldbus modules

3.1 Long distance bus module Bus participant in the long distance bus; e.g. Lenze controller with INTERBUS

module (slave). Networking does not require bus terminals.

3.2 Remote bus cable Connects the INTERBUS master interface module with the bus terminal and/or

the long distance bus modules.

4 INTERBUS loop,

peripheral bus

Fig. 5.4-2 Po s. 4

Connection in a peripheral-bus station

A peripheral-bus station consists of:

• a bus terminal (Fig. 5.4-2 pos. 2)

• up to eight peripheral bus modules (Fig. 5.4-2 pos. 3)

4.1 INTERBUS loop module Bus participant in the INTERBUS loop; e.g. Lenze controller with INTERBUS loop

module 2112

4.2 INTERBUS loop cable Connection within the loop

Features:

Communication medium RS485

Network topology Ring

Maximum number of

controllers

Dependent on INTERBUS master (e.g. Phoenix Contact G4-Master).

For the following data, always the smaller value applies dependent on the fact, whether

PCP communication is available or not:

• With PCP communication: 62 or

• Wit hout PCP communication: 256/number PD

Baud rate / cable length

Baud rate Maximum cable length between

neighbouring participants

500 kBit/s 400 m

2MBit/s 150 m

Specification of INTERBUS remote bus cable 26

Cable type Yard goods:

IBS RBC Meter-T, order No. 28 06 28 6 (Fa. Phoenix Contact)

Number of conductors 3 x 2, paired with common shielding

Conductor cross-section >0.2mm

DC cable resistance <96Ω/km

Impedance, characteristic 120 Ω±20 % (f = 64 kHz)

100

Ω±15 Ω (f > 1 MHz)

Capacitance per unit length < 60 nF/km (f = 800 Hz)

If necessary, supply the 2113 fieldbus module with a separate supply voltage 24

V DC via the two-pole plug connector ±10 %.

Plug connector Name Explanation

+ Vcc24 External supply 24 V DC ± 10 %, 120 mA

- GND24 Reference potential for external voltage supply

Use a separate power supply unit in each control cabinet.

Controller External voltage supply

820X Always required

821X / 822X / 824X and

93XX

Only necessary if the mains which supply the corresponding controllers is to be switched

off but the communication must not be interrupted.

8200 vector See information in “internal DC voltage supply”

External DC voltage supply 27
