The FTC470XET protocol converter
16
4.4 BMS side of the FTC470XET
On the BMS side, the FTC470XET protocol converter can optionally be used as master or as
slave.
z
BMS address 1 = master mode
z
BMS address 2 to 30 = redundant master mode
z
BMS address 2 to 30 = slave mode
The following data types are available on the BMS bus:
4.4.1
Alarm and operating messages
Bender devices connected to the BMS bus are cyclically scanned for alarm and operating
messages. Each device can store up to 12 alarm and operating messages, which are organised
according to the channels 1-12.
4.4.2
Diagnostics and parameterisation
This data is only sent to the bus if requested by BMS commands.
4.4.3
Redundant master function
FTC470XET provides the "Redundant master" function. In the event of failure of the regular
master (bus address 1) after approximately 60 seconds this "Redundant master" takes over
the master function in order to control the BMS bus. If the regular master becomes active
again, the "redundant" FTC470XET returns the master function.
In case of failure of the regular master, first the device with BMS address 2 tries to become
redundant master. If it fails to take over the master function, address 3 will be the next and
so on. That means that an FTC470XET with BMS address 2 is more likely to take over the
redundant master function than a device with address 30.
4.4.4
FTC470XET in slave mode
If the FTC470XET is operated in the slave mode in the existing BMS environment, one of the
following devices has to act as BMS master:
z
IRDH275, 375, 575 software version 1.40 or higher
z
PRC1470 software version 1.82 or higher
z
TM1000 software version 1.82 or higher
z
FTC470XDP software version 1.31 or higher
z
FTC470XET software version 1.01 or higher
z
FTC470XMB software version 1.31 or higher
It is recommended to prefer the master mode in order to get faster data access.
The FTC470XET provides the redundant master function when a BMS address be-
tween 2 and 30 has been assigned to it.
Please note that the FTC470XET cannot be operated in combination with a PRC470
control and indicating device!
