HIMA HIMatrix series compact safety controller

HIMA HIMatrix series compact safety controller

The HIMatrix Compact System is a series of safety related controllers launched by HIMA, featuring a compact structural design that integrates a safety related processor system, multiple input/output channels, and communication interfaces within a metal casing. In addition to the controller, the HIMatrix compact system also includes remote I/O, which can be connected to the controller via safeEthernet to expand additional input and output channels.

These safety related controllers can be applied to applications up to SIL 3 level and comply with IEC 61508, IEC 61511, and IEC 62061 standards; For railway applications, it can also reach SIL 4 level and comply with EN 50126, EN 50128, and EN 50129 standards. The HIMatrix system has been certified for process controllers, protection systems, burner controllers, and machine controllers.

The design of the HIMatrix system follows the principle of "power outage tripping" - the system does not require any power supply to perform safety functions. Therefore, in the event of a malfunction, the input and output signals adopt a power-off safety state. Meanwhile, the controller can also be used for applications that follow the principle of "power on trip".

System variants and programming tools

The HIMatrix system is divided into different variants based on hardware layout and operating system version:

Programming Tools Processor Operating System Communication Operating System Hardware Layout

SILworX CPU-OS V8 and above COM-OS V13 and above L3

SILworX CPU-OS V7 and above COM-OS V12 and above L2

ELOP II Factory CPU-OS V7 and below COM-OS V12 and below L2

Important precautions:

The devices with hardware layout L3 have extension functions, such as multitasking or overload capabilities

The operating system for layout L3 cannot be used for layout L2 devices, and vice versa

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

Safety functions and operational requirements

3.1 Expected and Unintended Uses

The HIMatrix controller can only be used for intended applications under specified environmental conditions and can only be used in conjunction with approved external devices. When security related data is transmitted through public networks (such as the Internet), additional security measures such as VPN tunnels or firewalls must be taken. The fieldbus interface cannot ensure safety related communication.

3.2 Operating Environment Requirements

Requirement type, requirement content

The protection level complies with Level III of IEC/EN 61131-2

Pollution level complies with Level II of IEC/EN 61131-2

Altitude<2000 meters

The enclosure protection standard is IP20, and it can be installed in higher protection level enclosures as needed

Working temperature: 0 ° C to+60 ° C (test limit: -10 ° C to+70 ° C)

Storage temperature -40 ° C to+85 ° C

Power supply 24 VDC, -20% to+25%, requires SELV or PELV power supply

3.3 ESD protection measures

Attention: Electrostatic discharge may damage electronic components within the HIMatrix system! Only personnel with ESD protection knowledge can modify or expand the system or replace modules. When operating, ensure that the work area is free of static electricity and wear an ESD wristband. When not in use, ensure that the module is protected against electrostatic discharge, such as storing it in its original packaging.

3.4 Residual Risks

The HIMatrix compact system itself does not pose any direct danger. Residual risks may arise from:

Malfunctions related to engineering design

Malfunctions related to user programs

Wiring related faults

Equipment monitoring function

4.1 Working voltage monitoring

The device continuously monitors the 24 VDC voltage during operation and takes corresponding measures based on the voltage level:

Voltage level equipment response

Normal operation at 19.3-28.8 V

<18.0 V alarm status (internal variable written and provided to input/output)

<12.0 V input and output shutdown

The Power Supply State system variable is used to evaluate the operating voltage state through programming tools or user programs.

4.2 Temperature status monitoring

One or more sensors are used to measure the temperature at relevant locations within a device or system. The temperature state [BYTE] system variable value changes as follows:

Temperature Range Temperature Status

<60 ° C is normal (0x00)

High temperature range of 60 ° C to 70 ° C (0x01)

>70 ° C very high (0x03)

If the "very high" temperature state frequently occurs, HIMA recommends improving the system's heat dissipation conditions to maintain the longevity of the HIMatrix system.

Event recording function - L3

The HIMatrix system is capable of recording alarm and event sequences.

5.1 Event Types

Boolean event: a change in the state of a Boolean variable, such as a change in numerical input. Alarm and normal states can be assigned arbitrarily.

Scalar event: Exceeding the limit defined for scalar variables. Scalar variables have numerical data types, such as INT and REAL. Two upper limits and two lower limits can be set.
