Example2:
Get DI data (Class ID: 0x64, Instance ID: 0x01, Attribute ID 0x01).
If the node ID of the CAN-2054D is 1, and the master (id: 0x0A) has completed
“Explicit” connection with the device. By getting the value of the object with
attribute ID 0x01, you can get the channel 0 ~ 7 of the DI data.

Get the value of Application Object1 with Instance ID 0x01 and Attribute ID 0x01.
After sending the
“Get Attribute Single”, the slave device response the DI data
(0x0F) at byte 2. The value 0x0F means that the status of DI3, DI2, DI1 and DI0
are turned on and others are turned off.
By changing the Instance ID and Attribute ID of the Application Object, you
can get other parameters of this device.
The Attribute 0x03 of Application Object1 can control the DO power on
value of each channel. After setting this attribute, the DO channels will output
DO power on value when booting up.
Attribute 0x04 and 0x05 of Application Object1 are used for safe value
configuration when
“Explicit Message Timeout” error occurs. When setting the
channel selection value of the Attribute ID 0x04 to
“0x1”, the safe value of
Channel 0 will be active. If the value is set to 0x4, it means that the safe value
of the channel 2 is active. Afterwards, you can configure the output safe value
of this channel by setting the value of Attribute ID 0x05. When setting the
Attribute ID 0x04 to
“0x1” and Attribute ID 0x05 to “0x1”, the channel 0 will turn
ON while the error occurs.
