Setting of the MB3.10
After the electrical connection, all required settings must be made at the FC3.10 "Client" und not
at the MB3.10.
For this, navigate to the menu item
Scan Modbus: Menu → General settings → Commissioning
by using the installation user code
9856
(possibly installation code
0011
for customer specific
controller versions). A search run starts which assigns the connected controllers in the cascade
system and the connected MB3.10. As soon as the MB3.10 (as well as the FC3.10 controller)
are identified,
OK
is displayed in the respective line. After all components have reached the
status
OK
, leave the menu via the
Back
button.
In the main menu at the client, now an additional menu
item appears: Modbus Gateway MB3.10.
As in the previous chapter, the Modbus transfer
parameters must have identical settings for all devices
connected to the BMS.
The speed of the data transfer is set by the parameter
Baudrate.
Further setting parameters
such as
Data bits, Stop bits
and
Parity
describe the basic Modbus communication technology
and must be identical to the parameters of the BMS which is meant to be connected.
The
Timeout
parameter is the period of time in which at least one communication between the
BMS and the MB3.10 must take place. If no communication takes place within this period of
time, the FC3.10 controller interprets this as "
Timeout error
".
Via the entry
Factory settings
, you can reset the MB3.10 to the default settings. The last menu
item
Information
shows the current firmware and bootloader version of the MB3.10.
