•
Expansion code
When accessing to the memory shown below, set the expansion code in addition to the type and address.
* If there is no need to set the expansion code, set “00” (= 3030 in the ASCII code).
•
Port number
Set the port number used for 1 : n connection (multi-drop)
For 1 : 1 connection or n:1 connection (multi-link), the port number setting is not used. Alternatively, set “00” (= 3030 in
the ASCII code).
•
System reserved
Enter “0” (= 30 in the ASCII code) for the number of bytes.
The number of bytes for “system reserved” varies depending on the model.
Example:
Sum Check Code (SUM): 2 Bytes
Data is added up (SUM), and the lower one byte (8 bits) of the sum is converted into a two-digit ASCII code (hexadecimal).
A sum check code is shown below.
Example: Transmission mode: without CR/LF, with sum check
Command: 20 (data read)
Address:
10 words from $u1000 (03E8H)
When reading, a sum check will be performed as shown below.
Response Code: 2 Bytes
“ACK” code is received at normal termination, and “NAK” code at abnormal termination. The following table shows the details
of each code.
