8.3 Predefined Protocol Support Function Instruction
Operation error
Upon completion with an error, the completion status indication device (d)+1 is turned on and an error code is stored in the
completion status (s3)+1.
For the error code stored in the completion status (s3)+1, refer to the following.
MELSEC iQ-R Ethernet User's Manual (Application)
Precautions
• If an error occurs in the mth protocol while multiple protocols are being executed, the instruction does not execute the
"m+1"th protocol and after and is completed with an error.
• When a protocol including no-conversion variables is executed, the total data length of the variables used in one packet
may exceed 1920 bytes. In this case, the instruction may obtain CPU device values over several scans. Therefore, do not
change the CPU device values specified in non-conversion variables from the start of the instruction to the end of
execution.
• Protocol cancellation
• The SP.ECPRTCL instruction itself does not open/close a connection and therefore the SP.SOCOPEN/SOCCLOSE
instructions need to be used to open/close the connection.
Page 1085 SP.SOCOPEN,Page 1088 SP.SOCCLOSE
• If same instructions are executed for the same connection, the subsequent instruction is ignored and is not executed until
the preceding instruction is completed.
• If the receive waiting time is set to "0: Infinite wait", the SP.ECPRTCL instruction is not completed until the data specified in
the protocol setting is received.
Error code
(SD0)
Description
3405H
(s1) is not a value in the range from 1 to 16.
• The SP.ECPRTCL instruction is completed with an error and stores the protocol cancel request error (C404H) in the device (completion status) specified by
(s3)+1.
• If a cancel request is issued while no protocol is being executed, the CPU module completes the cancel request without performing any processing.
• While no communication protocol is used, any cancel request is ignored if issued.
• When multiple protocols are executed continuously, a cancel request may be issued during execution of the nth protocol. In this case, the CPU module
forcibly terminates the nth protocol and does not execute the subsequent protocols. Protocol number n being executed is stored in the device specified by
((s3)+0), the receive packet number successful in comparison match is stored in the device specified by 1 to (n-1), and the protocol cancel request error
(C404H) is stored in the device specified by ((s3)+1).
• The CPU module periodically checks for a cancel request. For this reason, it may take time until cancel processing is performed after a cancel request is
issued.
