6.4 Taking over or returning the Master function
Certain commands in a BMS network can only be carried out when the FTC470XMB takes over the
Master function. This is required for the parameterization of BMS devices, for example.
When BMS address 1 is continuously assigned to the FTC470XMB , taking over of the Master function
is not necessary.
6.4.1 Taking over the Master function
Writing to FTC470XMB (= output data of the Modbus RTU Master)
Table 6.11: Master request: taking over of the Master function by FTC470XMB
Reading from FTC470XMB (= input data of the Modbus RTU Master)
Table 6.12: FTC reply to: taking over of the Master function by FTC470XMB
Taking over of the Master function is not required for requesting alarm and operating messages, meas-
uring values and in case of control functions for EDS systems.
The FTC470XMB must take over the Master function in case of parameter re-
quests and new parameter settings!
Take into account that the Master function must be returned by the FTC470XMB
after taking over the Master function and the subsequent parameterization.
