Setting of the Modbus configuration register
The following data format must be used to set the configuration registers. Register address
406h is used for illustration purposes.
All usable BMS instruction codes are listed below:
The BMS instruction codes 30, 32, 35, 37, 39 and 48 listed in the table are used for the inquiry
of parameters in Mode 1 and require that FTC470XMB is operating in Master mode.
Master mode is achieved by assigning BMS address 1 or automatically achieved in mode 1
by temporarily taking over the Master function.
If the FTC470XMB needs to operate as Master in an existing BMS environment, only the fol-
lowing devices can temporarily return their Master function:
●
EDS460/461, EDS490/491 software version 2.00 or higher
●
FTC470XDP software version 1.31 or higher
●
FTC470XET software version 1.00 or higher
●
FTC470XMB software version 1.31 or higher
●
IRDH275, 375, 575 software version 1.40 or higher
●
