Cause

The total packet size of receive data is smaller than that set in protocol data.
The receive data do not match the value set in protocol data.
When the code type setting is "ASCII Hexadecimal", data not in ASCII code are received.
The received length value exceeded 2046 bytes.
The Length value received from the external device does not match the actual length.

Description
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

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
*1
b15)
The configuration is the same as receive packet No. 1.
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.)
Cancels the protocol executed in Connection No.1.
0: No cancellation instruction
1: Cancellation request (set by user)
2: Cancellation completed (set by system)
