The figure 1.8 shows the block diagram of the I-8124W module.
1. DPRAM :
The DPRAM provides the communication channel between PAC (WP-
8000 or XPAC-8000) and I-8124W module.
2. EEPROM :
The EEPROM stores the configuration information. While activating the I-
8120W, the
“ScanList” will be loaded from EEPROM automatically.
3. CPU :
This CPU is for implementing the DeviceNet protocol and communicating
with the main control unit such as WP-8000 or XP-8000.
4. CAN Controller :
The CAN controller is used for sending and receiving the CAN messages.
I-8120W provides the photo isolation function between CAN controller
and CAN bus.
