FIELDBUS COMMUNICATION Protocol Address Type Parameter Name Representation Default value 3016h Read only Fieldbus control en- abled 0 = Off, 1 = On 0 3017h Read only Fieldbus address 0 – 255 255 3018h Read only Fieldbus download parameter 0 = dPOff , 1 = dPOn 1 3019h Read only Fieldbus fault reac- tion 0 = Trip, 1 = Switch to local 0 301Ah Read only Fieldbus fault reset type 0 = Hand, 1 = Auto 0 301Bh Read only Fieldbus interface type 0 = Fieldbus plug, 1 = Modbus RTU 0 301Ch Read only Internal Modbus RTU timeout 5 – 600 = 0.5 – 60.0 [s] 5 301Dh Read only Internal Modbus RTU Baud rate 0 = 9600, 1 = 19200, 2 = 38400, 3 = 57600, 4 = 76800 1 301Eh Read only Internal Modbus RTU frame format 0 = 8o1, 1 = 8e1, 2 = 8n2, 3 = 8n1 1 1) A specific softstarter size in itself will have a much more narrow range defined by its rated current and only values within that range will be accepted.
3.6.1. Configure baud rate Register at protocol address 4064h contains the fieldbus baud rate parameter which can be both read and written. To write this parameter, use Modbus function code 6 Write Single Register or 16 (10h) Preset Multiple Registers. To read this parameter, use Modbus function code 3 Read Holding Registers or 4 Read Input Registers. Response data or data to write is (baud rate / 100) and consists of two bytes. Note that after changing the baud rate, communication with the slave will no longer work un- til the baud rate of the Modbus master has also been changed to the same value. © Copyright 2019 ABB.
