Overview 5 (40)

2 Overview

2.1 Introduction

The Netbiter I/O Extender series provides a solution for distributed I/O requirements. The I/O system consists of stand-alone digital and analog input/output modules connected together on a RS-485 two-wire multi-drop network.

The modules communicate using the Modbus RTU protocol. The 32-bit ARM CPU in the module provides high speed data processing and fast communication turnaround times. Multiple baud rates are selectable, from 2400 to 115200 baud.

All I/O modules fit directly onto an industry standard DIN rail. All modules have a minimum isolation of 1000 VAC rms between the field and logic.

The modules are equipped with status LEDs to indicate the status of the inputs and outputs. This visual indication assists with fault finding and diagnostics.

2.2 Data acquisition

The primary use of the Netbiter I/O Extender modules is for data acquisition in combination with a Netbiter EC or WS gateway. The Netbiter gateway acts as a Modbus master which retrieves and sends data from the Netbiter I/O Extender modules.

3 General/Common Characteristics

3.1 Dimensions

• The module clips directly onto an industry standard DIN rail (EN 50022).

• Field wiring is on the front of the module via a plug-in connector.

• Module power and RS-485 communications wiring are on a separate plug-in connector on the bottom side of the housing.

• Allow at least 25 mm in front of and below the module to accommodate the wiring.

• Ensure that the space above and below the module is sufficient to provide adequate ventilation.

General/Common Characteristics 7 (40)

3.3 EMC Considerations

The I/O modules will usually be installed in an enclosure along with other devices that generate electromagnetic radiation, such as relays and contactors, transformers, motor controllers, etc. Electromagnetic radiation can induce electrical noise in both power and signal lines. Direct radiation into the module can also have a negative effect on the system.

Appropriate grounding, shielding and other protective steps should be taken at the installation stage to prevent interference. Protective steps include control cabinet grounding, module grounding, cable shield grounding, protective elements for electromagnetic switching devices, correct wiring, as well as the consideration of cable types and their cross sections.

• Use screened twisted pair RS-485 cable with the screen grounded at one point.

• Use screened I/O, T/C, and RTD cables, with the screens grounded at one point as close as possible to the I/O module.

3.4 Network Termination

Transmission line effects often present a problem on data communication networks. These problems include reflections and signal attenuation.

If it should be necessary to eliminate reflections from the ends of the cable, the cable can be terminated with a resistor across the line equal to its characteristic impedance. Both ends should be terminated, as propagation is bi-directional. In the case of an RS-485 twisted pair cable, this termination is typically 120 Ohms.

The baud rate value is programmed directly into the baud rate register. The only exception is the 115200 baud rate, where the value 11520 is used.

The reply delay is a time delay between the Modbus message being received to the reply being sent. In some applications where a modem or radio is used in the RS-485 network, it may be necessary to add a reply delay due to turnaround delays in the equipment.

IOX-4RO – Relay Outputs 10 (40)

4 IOX-4RO – Relay Outputs

4.1 Description

The IOX-4RO module has 4 normally open/closed relay outputs. This module may be used for a higher drive capability, or when isolation between outputs is required.

When switch 9 is OFF, the module is configured as a Modbus slave and the outputs are written to by the Modbus master (PC/PLC/HMI). Each output on the module can be individually switched ON or OFF, or all outputs can be set up at the same time by writing a single number to the output register that represents the status of all outputs.

An output watchdog timer can be configured to switch off all outputs if there has been no communication with the module for up to 255 seconds. A value of 0 seconds will disable this timer and the outputs will remain in the last programmed state.
