Yokogawa-ProSafe-RS
Overview
The Yokogawa ProSafe-RS safety system is IEC 61508 and ANSI/ISA 84 compliant and the world’s first truly integrated ‘safety PLC’ for the process industries. It has been used in more than 2,400 projects, ranging from large-scale integrated process automation projects to stand-alone safety solutions.
ProSafe-RS ends the traditional incompatibility between distributed control systems (DCS) and safety instrumented systems (SIS), allowing both to operate in one integrated environment with absolute integrity.
Engineering & Design
Conventionally, a DCS and an SIS required two separate monitoring and operating environments, different communications, and distinctive hardware architectures, escalating project time and expense. ProSafe-RS removes this barrier with its integrated architecture, providing the safety functions required for process protection within a unified engineering environment.
Yokogawa builds ProSafe-RS systems with competence, life cycle support, and long-term sustainability in mind, and the system supports the full safety lifecycle from design and engineering through operation and maintenance, backed by Yokogawa’s global service organisation.

For process plants implementing safety functions, the Yokogawa ProSafe-RS safety system is a proven platform, and Seven Star LLC supplies the Yokogawa ProSafe-RS safety system with engineering support for safety projects.
Why Seven Star LLC
Seven Star LLC supplies Yokogawa ProSafe-RS safety system components for safety projects across the Gulf, with verified specifications and engineering support. Our team assists with safety system spares, module selection, and expansion of existing ProSafe installations.
We support oil and gas, petrochemical, and power plants with reliable B2B supply of safety system hardware throughout the GCC.
Safety Engineering
The IEC 61508 and ANSI/ISA 84 compliance of ProSafe-RS supports the safety lifecycle documentation that plant operators must maintain, and the integrated DCS-SIS architecture reduces the engineering and lifecycle cost of running separate systems. The 2,400-project installed base demonstrates the platform’s maturity.
Because the safety system shares the operating environment with the control system, operators see alarms, trends, and diagnostics in one view, improving situational awareness during process upsets.
Documentation & Supply
Seven Star LLC supplies Yokogawa ProSafe-RS components with technical documentation and support for module selection, spares planning, and system expansion.
Our specialists assist safety engineers with the hardware and records needed for reliable safety system operation.
The integrated architecture of ProSafe-RS also reduces the training burden, because engineers and operators work in one environment for both control and safety functions rather than two separate systems.
Long-term sustainability is a design goal of the platform, with Yokogawa providing lifecycle support that keeps the safety system maintainable over the life of the plant.
Safety lifecycle management also covers proof testing and diagnostics, and the integrated design of ProSafe-RS provides the diagnostic coverage and documentation that support these activities throughout the plant life.
For plants standardising on Yokogawa, the common engineering environment of ProSafe-RS and the CENTUM control system reduces engineering effort and keeps the safety and control databases consistent.
The safety system’s engineering tools support the design, verification, and documentation of safety functions, helping plants demonstrate compliance with their safety integrity requirements.
ProSafe-RS also integrates with Yokogawa’s asset management and field device tools, keeping the safety loop’s field instruments visible in the plant’s maintenance systems.
Safety instrumented projects should evaluate the Yokogawa ProSafe-RS safety system, and Seven Star LLC supplies the Yokogawa ProSafe-RS safety system with engineering support for ESD and F&G functions.
The ProSafe-RS platform integrates safety and control, and a Yokogawa ProSafe-RS safety system from Seven Star LLC is supplied with documentation for your safety case.

Identifying ProSafe-RS Spares and Expansion Parts
A ProSafe-RS system is built from controllers, I/O modules, communication modules, power supplies and field terminal assemblies, each with its own model code and suffix codes. When ordering spares or expanding a system, take the full model and suffix code from the label on the installed hardware, not just the base model. Suffix codes define options and revision levels, and the system software release in use on site determines which hardware revisions are supported.
- Full model and suffix code from each module label
- ProSafe-RS system software release installed on the engineering station
- Whether the modules are used in redundant or single configuration
- Integration with a CENTUM DCS, or stand-alone operation
Installation and Commissioning Considerations
Any change to a safety instrumented system must follow the site’s functional safety management process. Hardware additions and application changes should be covered by a management-of-change review, and the safety requirements specification kept up to date. After installing new modules, the application changes are downloaded from the engineering station and then validated through testing appropriate to the change, from loop checks on new I/O to a full functional test where the logic has been modified. Keep the system’s security and access controls in place throughout, since write access to a safety controller must remain restricted.
Maintenance and Lifecycle Management
- Carry out proof tests of safety functions at the intervals defined in the SIL verification.
- Review diagnostic alarms and the system event log regularly rather than only after a trip.
- Keep a spares holding that matches installed module revisions, especially for redundant modules.
- Track manufacturer lifecycle notices so obsolescence can be planned rather than reactive.
- Maintain controlled backups of the safety application after each approved change.
ProSafe-RS in Oman and the GCC
Oil and gas production, refining, gas processing, LNG and power facilities in Oman and across the Gulf make wide use of Yokogawa control and safety systems. For these plants, ProSafe-RS commonly provides emergency shutdown, fire and gas and burner management functions. Long plant lifecycles mean that dependable access to spare modules is as important as the original project delivery, particularly on remote desert sites where a missing module can mean extended outage.

EJA and EJX transmitters measure pressure, level and DP flow throughout oil and gas, chemical and power plants. Zirconia oxygen analyzers and the TDLS8000 are used for combustion control on boilers and fired heaters. FLXA analyzers monitor pH, conductivity and dissolved oxygen in water and process streams, and CENTUM modules are bought as replacements for running control systems.Ordering Yokogawa parts: what we need
Send the model and suffix code and the serial number from the nameplate, and for CENTUM modules the style code as well. For transmitters without a code we need span, output protocol, wetted materials, process connection, housing and the approval required. For oxygen analyzer spare parts give the detector and converter models, for example ZR22G and ZR402G, and the part number.Browse Yokogawa products by category: PLC & I/O Cards, Flowmeters, Pressure Instrumentation, Automation Accessories, Temperature Instrumentation.
