Expansion Module Wiring - Zmotion ZIO Series Manual

expansion module that corresponds to the combination value, and then they can
communicate with each other.
The factory default communication speed is 500 KBPS on both sides, there is no need
to set this, unless you need to change the speed.
The CANIO_ADDRESS command is a system parameter, and it can set the master-
slave end of CAN communication. The default value of the controller is 32, that is,
CANIO_ADDRESS=32 is the master end, and the slave end is set between 0-31.
The CAN communication configuration can be viewed in the "State the Controller"
window.
There are 8 dial codes on IO board whose hardware version is above V1.3, 1-4 are to
set CAN address, 5-6 are to set CAN speed, 7 means reserved, 8 means 120ohm resistor.
Dial ON, the resistor is connected. For old versions, there is no bit 7 and bit 8, one 120ohm
resistor is needed to connect externally.

2.3. Expansion Module Wiring

The ZIO digital expansion module is powered by a dual power supply. Except the main
power supply, an additional IO power supply is required to supply independent power for
the IO. Both the main power supply and the IO power supply use 24V DC power supply.
For ZAIO0802 analog module uses a single power supply, it only needs to connect to the
main power supply.
To prevent interference, separate the IO power supply from the main power supply.
Please select the expansion module according to the requirements, and select IO
mapping or axis mapping according to the resources of the expansion module.
