Parameter setting after the FTC470XDP has taken over the Master function
The examples below show the taking over of the Master function, the subsequent activity and the
Master return. All the examples are based on the assumption that the BMS address of the FTC470XDP
is 2. By assigning BMS address 1 to the FTC470XDP, it would anyway have the Master function.
Changing the operating mode of an alarm relay (107TD47)
The operating mode of the alarm relay of the insulation monitoring device 107TD47 with address 4
is to be changed from N/O operation to N/C operation. For that purpose, the protocol converter
FTC470XDP with BMS address 2 at first has to take over the Master function.
(output data):
The transfer of the Master function will be acknowledged
(input data):
The PROFIBUS Master sets the operating mode of the alarm relay of the 107TD47 to N/C operation:
(output data):
The changed operation mode is acknowledged
(input data):
The PROFIBUS Master instructs FTC470XDP to return the Master function to the initial Master (output
data):
The return of the Master function is acknowledged (input data):
