esc has delivered software for chillers used in nuclear industry for chilling water in the secondary circuit of a nuclear power plant. The platform Siemens Simatic STEP-7 PLC is used in safety-related applications (Class B).

esc imitates a behaviour of a system in real time with automatic, complex simulation. Requirements are validated and evaluated graphically. Test protocols are generated, revisions saved.

esc is a member of a consortium for R&D of ionizing radiation detection systems for applications in medical diagnostics, radiotherapy, radiation dosimetry, defectoscopy and other fields.

 

 

PLC Control of chillers

Software for PLC Control System, validation and verification

esc has delivered software for chillers used in nuclear industry for chilling water in the secondary circuit of a nuclear power plant. Chiller systems can be used in all industries.

Verification of the software product was conducted according to the internal Software Requirements. Validation of the software product was conducted according to the Customer Requirements.

The PLC Testbed was used to imitate a behaviour of the system in real time with automatic, complex simulation. Requirements are validated and evaluated graphically. The testbed provides automated generation of test protocols.

The software complies to the safety standards IEC 61508, IEC 62138 and RCC-E. The platform Siemens Simatic STEP-7 PLC is used in safety-related applications (Class B).

The Programmable Logic Controllers (PLCs)perform the supervisory control of the chiller systems and employ other sub-systems that also have embedded programmable controllers.

 

Plc testbed

Automatic testbed for PLC SW verification

The test bed is based on PC applications driven by external scripts. Tested application requirements are separated into Test Cases. Subject of verification can be the whole application, its part or even subsystem function library.

Test Cases are gathered in an input script file. Plug-in board for PC provides analogue and digital inputs and outputs. Console application running on Windows OS. Input script files and output report files in the CSV or MS Excel format. Test protocols are generated, revisions saved.

The testbed imitates a behaviour of a system in real time with automatic, complex simulation. Requirements are validated and displayed graphically.

Used in safety-related chiller application evaluation. Used with Siemens SIMATIC S7 PLCs.
