Introduction

This manual describes the technical characteristics of the device and its use. It provides information on how to install, start up and configure the module.

Structure and Use of this Manual

The content of this manual is part of the hardware description of the HIMatrix programmable electronic system.

This manual is organized in the following main chapters:

 Introduction  Safety  Product Description  Start-up  Operation  Maintenance  Decommissioning  Transport  Disposal

HIMatrix remote I/Os are available for the programming tools SILworX and ELOP II Factory.

Which programming tool can be used, depends on the processor operating system of the HIMatrix remote I/O, refer to the following table:

SILworX  CPU OS V7 and higher

ELOP II Factory   CPU OS up to V6.x

Table 1: Programming Tools for HIMatrix Remote I/Os

In the manual, the differences are specified by using:

 Separated chapters  Tables differentiating among the versions

Projects created with ELOP II Factory cannot be edited with SILworX, and vice versa!

Compact controllers and remote I/Os are referred to as devices.

Target Audience

This document addresses system planners, configuration engineers, programmers of automation devices and personnel authorized to implement, operate and maintain the modules and systems. Specialized knowledge of safety-related automation systems is required.

SIGNAL WORD

Type and source of risk! Consequences arising from non-observance Risk prevention

The signal words have the following meanings:

 Warning indicates hazardous situation which, if not avoided, could result in death or serious injury.  Caution indicates hazardous situation which, if not avoided, could result in minor or modest injury.  Notice indicates a hazardous situation which, if not avoided, could result in property damage.

Safety

All safety information, notes and instructions specified in this document must be strictly observed. The product may only be used if all guidelines and safety instructions are adhered to.

This product is operated with SELV or PELV. No imminent risk results from the product itself. The use in Ex-zone is permitted if additional measures are taken.

Intended Use

HIMatrix components are designed for assembling safety-related controller systems.

When using the components in the HIMatrix system, comply with the following general requirements.

Product Description

The safety-related F3 AIO 8/4 01 remote I/O is a compact system in a metal housing with 8 analog inputs and 4 analog outputs.

The remote I/O is available in various model variants for SILworX and ELOP II Factory, see Table 10.

Remote I/Os are connected to individual HIMax or HIMatrix controllers via safeethernet. They are used to extend the I/O level, but are not able to run any user program by themselves.

The remote I/O is suitable for mounting in Ex-zone 2, see Chapter 4.1.4.

The device is TÜV-certified for safety-related applications up to SIL 3 (IEC 61508, IEC 61511 and IEC 62061), Cat. 4 and PL e (EN ISO 13849-1) and SIL 4 (EN 50126, EN 50128 and EN 50129).

Further safety standards, application standards and test standards are specified in the certificates available on the HIMA website.

Safety Function

The remote I/O is equipped with safety-related analog inputs. The input values on the inputs are safely transmitted to the connected controller via safeethernet. The outputs are safely assigned their values by the connected controller via safeethernet.

Safety-Related Analog Inputs

The remote I/O is equipped with 8 analog inputs with transmitter supplies for the unipolar measurement of voltages, referenced to L-. The remote I/O is intended to measure the voltage on the inputs. To measure the current on the inputs, the inputs must be connected with external shunt adapters, see Table 4. Only shielded cables must be connected to the analog inputs. Each analog input must be connected to a twisted pair of wires. The shielding must be connected to the remote I/O and the sensor housing and earthed of one end to the remote I/O side to form a Faraday cage.

If an open-circuit occurs during voltage measurement (the line is not monitored), any input signals are processed on the high-resistance inputs. The value resulting from this fluctuating input voltage is not reliable; with voltage inputs, the channels must be terminated with a 10 k resistor. The internal resistance of the source must be taken into account. For a current measurement with the shunt connected in parallel, the 10 k resistor is not required. The analog inputs are designed to retain the metrological accuracy for 10 years. A proof test must be performed every 10 years.

Reaction in the Event of a Fault If the device detects a fault on an analog input, the AI.Error Code parameter is set to a value greater than 0. If a device fault occurred, the SILworX system parameter Module Error Code is set to a value greater than 0, or if ELOP II Factory is used, the Module.Error Code signal is set to a value greater than 0. In both cases, the device activates the FAULT LED. In addition to the analog value the the error code must be evaluated. The analog value must be configured to ensure a safety-related reaction. The error code allows the user to configure additional fault reactions in the user program. Line Monitoring for Digital Outputs The analog inputs (AI) of the F3 AIO 8/4 01 can also be used to monitor the line for open circuits and short-circuits of digital outputs of other HIMatrix controllers (line monitoring). To this end, the transmitter supply must be set to 26 V. To do so, set the Transmitter Voltage[01] parameter in SILworX and ELOP II Factory to 2, see Table 29 and Table 33. Requirements Using HIMatrix devices with analog inputs, the digital outputs of any HIMatrix controller can be monitored under the following conditions: 

  The transmitter supply of analog inputs exists, 

  An external shunt can be connected to the analog inputs. These conditions apply for all systems within the HIMatrix family, from compact to modular systems. Examples The digital outputs of the F2 DO 16 01 or F20 can be monitored with the analog inputs of the F3 AIO 8/4 01. The analog inputs of the F3 AIO 8/4 01 can monitor the digital outputs of the DIO 24/16 01 (modular system). Figure 1 shows how the lines connecting a digital output (DO) to an actuator (e.g., solenoid valve) can be monitored for open-circuits and short-circuits.
