Expertise
Automation and supervisory control
We bring equipment from different vendors into one control system and deliver the data to the control room.
What the solution consists of
From the sensor to the operator's mimic diagram: controllers, an industrial network, gateways, SCADA servers and telecontrol on standard protocols.
Controllers and I/O
PLCs, I/O modules, variable frequency drives, operator panels; connection of sensors and actuators.
Industrial network
A ring on industrial switches, dedicated VLANs for control, redundant links to the control room.
Gateways and protocols
IEC 60870-5-101/104, IEC 61850, Modbus RTU/TCP, OPC UA, DNP3; converters for equipment with serial interfaces.
SCADA and servers
Redundant SCADA servers, archives, operator workstations, web clients for management.
Telecontrol
Telesignalling, telemetry and telecontrol commands: bay controllers, RTUs, exchange with dispatch centres.
Control room
Mimic diagrams, event and alarm logs, reports, operator access rights, a common time base for events.
How it works: a scenario
The tank level exceeds its setpoint: the sensor signal passes through the PLC and SCADA to the operator, and the telecontrol command returns over the same communication lines to the valve and the pump.
Normal operation
The level transmitter sends its measurement to the PLC; the controller passes it over the industrial network to the SCADA server and the control room. On the mimic diagram the level trend stays within the setpoint band.
Event
The level rises and crosses the high setpoint. The PLC registers the violation, the section status changes in the control room, and a time-stamped event enters the log.
Telecontrol command
The operator issues a command: it passes through SCADA and the PLC to the actuator — the valve closes, the pump stops, and execution is confirmed in the log.
Result
The level returns to normal and the status clears. The log keeps the whole sequence — signal, alarm, command, confirmation — on a common time base.
What we do
- Telecontrol: telesignalling, telemetry and telecontrol commands, exchange with dispatch centres over IEC 60870-5-104
- SCADA and process control systems: architecture, redundant servers, operator workstations
- IEC 60870-5-101/104, IEC 61850, Modbus RTU/TCP, OPC UA and DNP3 protocols
- Industrial gateways and protocol converters for equipment without Ethernet
- PLC and operator panel programming, variable frequency drive set-up
- Mimic diagrams, event and alarm logs, archives and reports
- Integration with existing systems without stopping production
- NTP and PTP time synchronisation, a single sequence of events
- Commissioning, testing under a programme, documentation
- Support: backups of projects, changes on request, diagnostics
How the work goes
Survey
A list of controllers, protocols and links; what delivers data and what does not; an as-is diagram of information flows.
Design
SCADA and telecontrol architecture, signal tables, exchange diagram, specification of gateways and servers.
Development and bench testing
PLC projects, mimic diagrams and gateway configurations are checked on a test bench before the site visit.
Commissioning
Every signal is checked against the table, exchange with the dispatch centre is tested, reports and acceptance documents are drawn up.
Support
Backups of projects, a change log, changes on request, diagnostics.
Typical tasks
Controllers do not deliver data to SCADA
We select gateways and configure exchange over standard protocols.
Telesignalling and telemetry must reach the dispatch centre
We set up telecontrol and a communication link and verify it under a test programme.
Scattered systems
We merge them into one supervisory system with a common event log.
Equipment with serial interfaces
We connect it through Modbus RTU to TCP converters and gateways to IEC 60870-5-104.
The PLC project is lost
We upload the program from the controller, document it and store it in a version-controlled repository.
Event timestamps do not match
NTP or PTP time synchronisation on all nodes, a single sequence of events in the log.
What the customer receives
Signal tables and exchange diagrams
List of telesignalling, telemetry and telecontrol points, addresses, protocols, information flow diagram.
Projects and configurations
PLC programs, SCADA projects, gateway configurations and backups.
Commissioning reports
Signal checks against the table, exchange tests, acceptance reports, operator instructions.
Result: a working control system, integration over standard protocols, signal tables, projects and configurations.
Questions
Do controllers have to be replaced to connect them to SCADA?
As a rule, no: equipment is connected through gateways and protocol converters. Replacement is needed only if the controller supports no standard protocol and has no communication interface.
Do you work with a SCADA system implemented by another contractor?
Yes. We survey the project, document its actual state, and then modify it or take it under support.
How is data transfer to the dispatch centre confirmed?
Under a test programme: every signal is checked against the table with confirmation on the centre's side, and the result is recorded in a report.
Can commissioning be done without stopping production?
Yes: signals are checked section by section, and telecontrol commands are tested only in agreed windows at the request of the operations team.
