Introduction.
Purpose.The MCX “Monitor Module” software module is intended for building on its basis systems for remote monitoring and automation of process control, water and heat supply for central heating points, and dispatch control systems. The module carries out automatic measurement and indication of parameter values of heat supply and water supply systems (hot and cold), telemetric control and data collection via information networks.
Module features:
Table 1. List of functions and features of the monitoring module.
| Item No. | Description of the functionality and features of the module. |
| 1 | Simplicity: it is possible to connect equipment corresponding to the default input configuration to the controller without any additional settings (see paragraph 3). |
| 2 | Comfortable: in the case of an unsuitable configuration (by default) of the controller inputs to the connected equipment (sensor type, for example), you can easily make changes to the configuration using the controller display (see clause 1, clause 4.1). The main screen displays the states of the controller inputs and outputs (see section 2.2). Support for the controller menu in two languages: Russian and English. |
| 3 | Universal: there is no strict binding of the configuration of the controller inputs to specific equipment: the names of the configured controller inputs do not refer to a specific type of device. Can be used in any managed systems organized in a Modbus network. |
| 4 | Required in systems with a large number of devices: is a block with additional inputs for connecting discrete and analog devices to the managed system. |
| 5 | With built-in analog device status analysis system: monitoring device failures on analog inputs and sound notification when they occur. |
| 6 | Open: Using the Modbus protocol, it is possible to read the necessary information from the module, as well as remotely change configurable parameters. |

Controller specifications.
The MCX controller has two interfaces that allow you to connect external devices via the network:
CAN, for connecting devices via a local CANbus network;
RS485, for connecting devices via the Modbus network (Mobus RTU communication protocol).
