Chapter 5 Configuration of Communication parameters
[ About the valid combination of CPU and the range of I/O area ]
1. Specify CPU Type correctly, before configuring the items of ASR I/O Area Setting.
2. Don’t change the value of CPU Type, after configuring the items of ASR I/O Area Setting.
It can cause an error indication.
3. If the error happened, disconnect from EH-ETH2.
4.Before changing the value of CPU Type, we recommend to set the default value of ASR parameters by
clicking [default set] button in ASR parameters window.
5. The valid combination of CPU and the range of I/O areas is shown in
Table 5.20.

*1 : The upper address is the maximum address. The validated address follows I/O assignment.
*2 : u means unit No.. s means slot No..
*3 : Slave station No.8 and 9 at the time of the remote use are for expansion.
If these address are set to Send/Receive area, EH-ETH2 detects an error at the time of Sending or Receiving.
*4 : A number is not assigned to DIF and DFN of EHV-CPU.
