Brief information on MOD-Bus A defined address is assigned to every device that is connected via Modbus over which it can send and receive Modbus commands. The communication within the network is always begun through a master. It sends a message to which the addressed slave reacts, depending on the contents. Modbus is a standardised protocol which is openly accessible. In general, there are two versions of the Modbus, i.e. one uses communication via serial interface, the other via Ethernet. Our Modbus coupler is a module with serial interface which transmits the data via Modbus RTU. A transmission of the data via Modbus RTU means that the data are sent in binary form and that these must first be converted into a readable form after the transmission. Modbus interface 1. Control of the system via TopTronic®T: The MOD-Bus coupler is connected to the TopTronic®T heating regulator via the T2B bus (internal TopTronic®T bus). All data points of the heating regulator can be accessed via this T2B bus. Each of the data points out of the TopTronic®T has a unique address which can be selected depending on the application. The forwarding of information to the GLT about temperatures of individual mixing circuits, pump statuses, alert messages from heat generators (incl. alert codes), etc. is thus possible. The hardware use with the solution of a MODBUS coupler is low, because even with a cascade network with multiple TopTronic®T controllers, only 1 MOD-BUS coupler is required in order to query the information of the entire system. 2. Control of the system via GLT: The GLT actively engages in the control of the heating system. In this case, all units (diverse mixing circuits, water heaters, etc.) are not activated via the TopTronic®T, but rather via the GLT. The Hoval boiler only supplies the required heat still, which is also passed via a data point (temperature set value) from the GLT to the heat generator or to the cascade. Connection to other bus systems The various manufacturers of home heating, ventilation, air conditioning systems work with different protocols (communication language between network participants) such as LON, EIB, Profibus, Canopen, etc. In order to facilitate the communication with these systems, the BUS coupler is used as link (between the third-party systems and the MOD-BUS). The open standard of the MOD-BUS communication protocol allows different third-party systems to be connected together to form a network. In this case the connection to other communication protocols is created via a Universal Gateway. The data transfer is handled via the MOD-BUS coupler. Services such as commissioning, creation and connection of communication protocols require a use-oriented planning. Universal Gateways are (usually) available for 25, 50, 100 and 250 data points. Commissioning or connection of the coupler to the GLT The connection of the MOD-BUS coupler into the GLT network occurs via the operator of the building control. Basic technical information such as the addressing of the coupler and the required data points for connection are listed in the provided operating instructions. Should the translation of the MOD-BUS protocol to a different communication protocol (LON, EIB, ...) be necessary, a use-oriented planning is required. Testing the Modbus coupler: The Modbus coupler can be checked for the availability of the specified data points using various software tools. The data points available in the data point table can be accessed with the input of the corresponding addresses. The software tools are normally freely available via the Internet and serve for testing purposes during commissioning.

The status (ON/OFF) of the pump output of the mixing circuit 2 is collected via this data point.

Independently of which function is lying on the variable output (parameterisation TTT), the status (ON/OFF) is registered.

Independently of which function is lying on the variable output (parameterisation TTT), the status (ON/OFF) is registered.

The status (ON/OFF) of the pump output of the mixing circuit 1 is collected via this data point.

If a boiler circuit pump is parameterised at the controller (output «direct circuit», VA1, VA2), then «1» is returned via this data point if the output is active.

Switches on the output of the storage charg­ing pump, thus «1» is returned via this data point.

For two-stage heat generators, «1» is re­ turned with this status signal if the second stage is active.

Depending on which heat generator type is set on the controller, a corresponding sta­tus signal can be queried here. For mod­ u­lat­ing heat generators (H-GEN type 4/5) «1», if this is in operation with staged heat generators when the first level is active.
