AMiT Automation Controllers

AMiT Automation controllers offer two options for local control:

• Controllers with preloaded application – designed for standard applications where the user only sets the required parameters, after which the device operates according to the selected configuration.
• Freely programmable controllers – allow users to create their own control algorithm precisely according to the requirements of a specific project.

This makes it possible to select the appropriate balance between maximum flexibility and rapid commissioning without the need to create a custom application programme for each project.

All controllers support Modbus RTU communication protocol. Controllers with Ethernet also have Modbus TCP/IP and proprietary DB-Net/IP communication protocol. This allows the controllers to be easily integrated with control systems not only from AMiT production but also with systems from other manufacturers.

Controllers with Preloaded Application

Controllers with preloaded application are designed for clearly defined control tasks where there is no need to create a custom programme. Using parameterisation software, the user sets the required controller behaviour, after which the device operates independently according to the stored configuration.

This solution simplifies application preparation and reduces commissioning time. At the same time, it retains the option of adapting the controller’s functions to a specific installation and connecting it to a supervisory control system as required.

Freely Programmable Controllers

Controllers give the user the ability to create their own control algorithms, including screen design in units with displays, in the DetStudio development environment. Every single controller is designed with a specific number of inputs and outputs for a specific control application (HVAC, control of fan coil units, control of heating sources or heat lines, on-wall room control units, etc.) but the specific use and integration into a complex solution are only in the hands of the user algorithm creator, with no restrictions whatsoever. It is advantageous to use programmable room control units for freely programmable controllers as these drivers are based on the same programming concept and communication. For standard solutions and commonly used algorithms, there are sample solutions of application programmes freely available for users to use as they are or as an inspiration for original solutions of their own.

In terms of programming and utilisation, the freely programmable controllers are identical with graphic room controllers – HMIs of the AMR-OPxx series (AMR-OP83 and AMR-OP87). They can be used as very flexible devices not only for controlling or displaying data, but also as powerful control systems with internal web servers.
