Expansion Module Usage - Zmotion ZIO Series Manual

→ Wiring Note:
The wiring principle of digital output OUT (0-31) is shown in the figure above. The
⚫
external signal receiving end can be an optocoupler or a relay or solenoid valve, all
can be connected as long as the input current does not exceed 300mA.
For the connection of the public end, please connect the "EGND" port on the IO power
⚫
supply to the negative pole of the DC power supply of the external input device. If the
DC power supply of the external device and the controller power supply are in the
same power supply system, this connection can also be omitted.

3.8.5. Expansion Module Usage

(1) Please follow the above wiring instructions to do power, CAN and IO signal wiring
correctly.
(2) Assign IO address and communication speed ratio through DIP switch.
ON to enable front 6-bit.
(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) State values of relative input ports can be read directly through "IN" command, also,
it can be read through "ZDevelop/View/In". Please refer to "ZBasic" for details.
