In the field “ TimeOut (seconds) ” the maximum time that the device attends for the CAN
frames is defined;
In the field “ Modbus Register TO ” the value of Modbus register in which saving the status of
the CAN communication is defined. ‘1’ means that the communication is good and ‘0’ means
that at least one CAN frame is not received into the timeout defined;
If the field “ Enable Write CAN on Request ” is checked, the CAN messages in transmission
are sent when a specific Modbus register is written by the Master.
The meaning of the fields of “Modbus Slave” are:
In the field “ Baudrate ” the data rate of the RS485 bus is defined;
In the field “ Parity ” the serial parity is defined;
In the field “ ID Device ” the Modbus ID is defined;
If the field “ Cancel Data after Read ” is checked, the data for the CAN messages in reception
will be erased after the Modbus reading request;
If the field “ Not Cancel if read Input Registers ” is checked, the data for the CAN messages
