1.2.1 Command from master
A master device is, for example, a PC or a control device.
Initial synchronisation:
A transmission pause of at least 3.5 bytes is used for initial synchronisation.
The following byte is then interpreted as the first byte of a frame (i.e. address).
The pause between the individual bytes of a frame may be a maximum of 1.5 bytes.
Address:
The address field has a size of 8 bits.
Address values from 1 to 247 are permitted.
The address 0 is reserved for broadcast commands (i.e. commands to all fans in the network).
Command:
The following commands from the "MODBUS Application Protocol Specification V1.1" are supported:
Code
Command
0x03
Read holding register
0x04
Read input register
0x06
Write single register
0x08
Diagnostics
0x10
Write multiple register
Other commands are not supported.
The following additional commands are defined by ebm-papst:
Code
Command
0x43
Read Holding Register Addressed By Serial No.
0x44
Read Input Register Addressed By Serial No.
0x46
Write Single Register Addressed By Serial No.
0x50
Write Multiple Register Addressed By Serial No.
Data:
Depending on the command concerned, the number of data bytes and their meaning may differ.
Please refer to 1.3. Commands
