If CanBasicDataOut flag is not equal to zero, relevant measuring channel message is transferred via
CAN2.0B interface. If all CanBasicDataOut flags are equal to zero, no messages are transferred from the module
via CAN 2.0B interface, however, the module generates acknowledgment of successful message transfer of other
modules, connected to CAN2.0B bus.

I2C driven interface
I2C driven interface is designed for control of module operation and operating parameters setup. I2C interface
connector is located on the module front panel (data link connector). I2C driven interface parameters are strictly
defined, thus, independently from module current state, I2C interface is always accessible for module control.
Module setup can be implemented by means ПН31 setting unit, or PС. In order to setup by PC, dedicated
software should by run on PC and the module must be connected to PC via MC01 diagnostic interface board (RS232
Interface) or MC01 USB (USB interface).
Note. During the module setup by means of MC01 USB, virtual COM port drivers must be installed on PC
