Alarm trips: the ups and downs – Part 1

12 November, 2009

Something happens - a signal peaks or falls - and you need to know. A limit alarm trip can trigger the response needed to maintain normal, and safe, operations.


Failsafe controller gateway

26 October, 2009 by

Siemens has developed the Gateway CM104 TSAA, a migration solution for integrating Triconex failsafe controllers into Simatic PCS 7-based control systems. The Gateway enables existing systems to be expanded or modernised inexpensively and step by step.


Ethernet/IP safety controller

25 September, 2009 by

The NE1A is a programmable safety controller using function block- programming logic, which allows it to be used in a simple stand-alone application as well as in a full-scale safety solution. The controller is programmed via the built-in USB port, contains 16 safety inputs, eight transistor safety outputs and four test pulse outputs. The NE1A also has DeviceNet and ethernet/IP as onboard communication protocols.


Safety system control software

25 September, 2009 by

Samos Plan v1.2 is the control software for Wieland’s Samos PRO modular safety products.


Speed sensor and safety controller

21 September, 2009

Rockwell Automation has released the Allen-Bradley Guardmaster MSR57P speed monitoring safety relay, the speed sensor and safety controller in a single device.


Integrated speed sensor and safety controller

21 August, 2009 by

The Allen-Bradley Guardmaster MSR57P speed monitoring safety relay effectively combines the functionality of a speed sensing module with a configurable safety controller. The MSR57P is suitable for safety applications where access is required to guarded areas, under defined and controlled conditions, while a machine is still running.


Fail-safe software controller

21 August, 2009 by

The Simatic WinAC RTX fail-safe software controller for PC-based automation allows safety-related tasks to be performed via PC.


Safe zero-speed/slow-speed monitor

25 June, 2009 by

The Wieland SNS 4084K standstill monitor enables machinery operators in process industries to safely monitor two input signals in the 0.1 to 99 Hz frequency range.


Safety I/O module

25 June, 2009 by

The Allen-Bradley Point Guard I/O module is a modular, 24 V DC I/O system that is designed to fit into the standard Point I/O system, offering both automation and safety functionality in a maximum-density I/O solution.


SafetyNet controller

25 June, 2009 by

The PAC8000 SafetyNet has been approved by TÜV for applications requiring the handling of safety and process control data in the same controller. In addition, the availability of a 24 VDC power supply extends the locations where SafetyNet systems can be implemented.


Uptime and the new age of safety control

12 June, 2009 by Gary Milburn*

Unleashed by new safety standards that embrace the latest microprocessor technologies, modern safety control systems are now intricately tied to how the plant operates — not only optimising worker safety, but improving productivity and uptime.


Decentralised machine control

09 June, 2009 by

The PSS4000 automation system and PAS4000 software suite provides integration of safety, standard and motion control, as well as visualisation and diagnostics. All data is conveyed via a SafetyNET p ethernet-based industrial fieldbus network.


Steel recoiler safety controlled

20 January, 2009

It’s often a requirement of many manufacturing processes to have the operators become directly involved in the machine action at the unloading point, either to unload or secure the outbound product. Unfortunately, the outfeed sections of most processes are notoriously dangerous, so in reality we should be striving to remove the operators from the area at all times.


Modular safety system

05 October, 2008

The Sirius 3RK3 modular safety system MSS offers an enhanced safety solution that combines the functionality of a simple safety relay and a fail-safe programmable logic controller.


Safety system

08 July, 2008

The XMR system architecture of the HIMax safety system allows users to adjust the redundancy of individual modules to the requirements of the differing process loops. XMR refers to the degree of modular redundancy in the system, with ‘x’ assuming any value between one and four.
