The baud rate on the Modbus Master plug in is fixed to 19200 Baud,
“Even” parity and one stop bit. To run
external devices, it is necessary to set a unique Modbus address but equal Baud rate, Stop bit and parity
configuration in the proprietary configuration procedure of each device. After that the devices can connected
to the bus. The address of each device must be set in the configuration of the ECB-D10. By the next reset of
the board automatically all devices are configured in a proper way by the controller. The current implemented
devices are:
•
Variable speed drive, Emerson ED3015A
•
Soft starter, Carlo Gavazzi RSBT4025EVC
•
EC Fan, EBM ESM
