Electronic control system for electrostatic precipitators connected in series

An electronic control system for a number of electrostatic precipitators of a building ventilation system, the electronic control system comprising:

• at least one master device and a plurality of node devices,
• wherein
• each of the plurality of node devices is coupled to a corresponding electrostatic precipitator,
• the at least one master device and each node device having a respective computing unit,
• each node device having a respective node configuration program,
• at least one chain of node devices is connected to the at least one master device,
• wherein in each chain of node devices a first node device is directly connected to the associated master device and the further node devices of the chain of node devices are each connected to a predecessor node device, so that the node devices of the chain are connected to one another in series,
• the at least one master device being the predecessor of the first node device of the connected chain of node devices, and
• a position number is assigned to each of the node devices,
• and wherein, the computing unit of the at least one master device, is configured, in a configuration mode, to cause the computing unit of the first node device of each connected chain to execute its node configuration program:
• wherein, each node configuration program of each node device is configured
• to receive the position number of its predecessor and to assign itself a position number increased by the value 1 relative to the position number of its predecessor and to store the position number assigned to itself in its respective node device, and
• to determine whether a subsequent node device is connected and,
• if this is the case, to cause the computing unit of the subsequent node device to execute its respective node configuration program, and
• if this is not the case, to transmit its position number to its predecessor node device, which in turn transmits it to its predecessor node device until the associated master device receives the position number from the first node device of the chain.
