MR07-PLC basic module controller with AKP
Microprocessor-controlled control device for controlling district heating transfer stations with the option of modular expansion to a total of ten heating circuits and additional recording of the heat meter data and forwarding of all data to a higher-level network optimization computer in the boiler house. The controller MR07-SPS is modular and can control and regulate in its maximum configuration a direct heating circuit, seven mixer circuits, a boiler circuit and a circulation circuit.
The MR07-PLC module controller is equipped with a graphic display with 128×64 pixels. To support menu selection and parameter input, there are also four symmetrically arranged buttons.
The MR07-PLC module controller is also equipped with a 2 Gigabite MMC card that can be used as program memory, parameter memory or trend memory. This makes commissioning standard systems a simple matter because MMC cards can be preprogrammed using a notebook. The SD card can also be used as a data memory for various bitmaps for graphic display on the controller and as a foreign language memory.
There are three ways to upload new application programs:
– Installation of a new MMC card
– Upload the program via a programming adapter
– Upload a program via the data interface and the boiler house computer
