A
Predefined protocol support function execution status check area
■Connection No.1 (Un\G8300 to Un\G8335)
The execution status of the predefined protocol support function is stored.
For addresses corresponding to connections after the connection No.2, refer to the following.
Page 336 List of buffer memory addresses
*1 The following table lists the verification result codes and causes of verification mismatch.
Address Name Description
Un\G8300 Protocol execution status Stores the status of the protocol being executed at
connection No.1.
0: Unexecuted
1: Waiting for transmission
2: Sending
3: Waiting for data reception
4: Receiving
5: Execution completed
Un\G8301 System area
Un\G8302 Received data verification result (receive packet No.1) Stores the verification results of receive packet No.1.
• Element No. where the verification result did not match
(b0 to b7)
0: Verification matched
1 to 32: Element No. where the verification result did not
match
FFH: Verification not performed
• The cause of mismatch (verification result code) (b8 to
b15)
*1
Un\G8303 to Un\G8317 Received data verification result (receive packet No.2 to 16) The configuration is the same as receive packet No. 1.
Un\G8318 Protocol execution count Stores the number of protocol executions in Connection
No.1.
0: Protocol not executed
1 to 65535: Number of executions (When the number
exceeds 65535, the value remains 65535.)
Un\G8319 Protocol cancellation specification Cancels the protocol executed in Connection No.1.
0: No cancellation instruction
1: Cancellation request (set by user)
2: Cancellation completed (set by system)
Un\G8320 to Un\G8335 System area
Stored value Description Cause
00H Normal
01H Insufficient receive data The total packet size of receive data is smaller than that set in protocol data.
10H Data not matched The receive data do not match the value set in protocol data.
11H ASCII-binary conversion error When the code type setting is "ASCII Hexadecimal", data not in ASCII code are received.
12H Data length error The received length value exceeded 2046 bytes.
30H Data length size error The Length value received from the external device does not match the actual length.
FFH Verification not performed
