(3) After powered on, please use ETHERNET or RS232 to connect to ZDevelop.
(4) Please use the "CANIO_ADDRESS" command to set the master's "address" and
"speed" according to the needs, and use the "CANIO_ENABLE" command to enable or
disable the internal CAN master function.
(5) After all the settings are completed, it is time to communicate, in "State the
controller"--"CAN nodes", it will show information of expansion module.
(6) Note that the "speed" settings of each node on the CAN bus must be consistent, and
the "address" settings cannot cause conflicts, otherwise the "ALM" alarm light will be
on, and the communication establishment will fail or the communication will be
disordered.
