Distributed control systems MSCU 7000 based on
controllers «ORION»
Distributed automation systems make it possible to deliver process units to the site in 100% factory-ready condition.

To achieve this, automation equipment is installed directly in the process units.
This method of automating a process unit is known as the topological approach.
The topological method allows for comprehensive testing of the process unit with its fully integrated control system to be carried out at the manufacturing plant.

Automation of individual process units is the first stage in automating a plant.
The second stage involves creating an integrated control system for the entire plant.
To achieve this, it is sufficient to connect the control systems of the individual process units via the plant’s interactive network.
To implement the topological automation approach, a range of technical components has been developed, specifically designed for installation directly within process units:
  1. Multifunctional Modules (MFM) – used to execute control algorithms. The MFM receives information and sends control commands to the process unit via the interactive network.
  2. Interactive Network Nodes (INS) – designed to convert sensor signals into digital form suitable for the MFM. These nodes connect to the interactive network and are mounted directly on the sensors.
  3. Actuator Control Units (ACU) – convert signals from the MFM into control actions for actuating mechanisms.

Each process unit is equipped with the required number of Interactive Network Nodes (INS) and Actuator Control Units (ACU), depending on the number of sensors and actuators used.

 The range of distributed PCS components includes several versions of INS and ACU, selected according to the type of sensor or actuator being used.

SPF "System-Service", at the request of customers, develops and manufactures the necessary UIS, BUMS and MFMs.

The figure shows an example of installing a UIS on sensors connected to an interactive network implemented via a power supply line.
The BOOM is installed by the developer of the technological unit in the immediate vicinity of the actuator, in any convenient location.

If necessary, the developer has the opportunity at any time to change the number of sensors or actuators in the unit, while the structure of the ACS remains the same – only the number of UIS and UMS will change.
The physical implementation of an interactive network between technological units is carried out through optical communication lines or a twisted pair.

The distributed ACS has the ability to scale to automate various modifications of the process unit, which makes it possible to adapt the system to changing production process conditions without changing the design and interface channels.
