16 ETHERNET INSTRUCTIONS
16.5 Executing the Protocols Registered for the Predefined Protocol Support Function
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.
• The connections for which the GP.ECPRTCL instruction can be executed are only those for which "Communication
protocol" is specified for the communication means.
• If a cancel request is received during execution of the mth protocol while multiple protocols are executed continuously, the
Ethernet module stores the protocol number m being executed in the device specified by (s3)+0, the receive packet
number successful in collation match for the already executed protocol in the device specified by 1 to (m-1), and the
protocol cancel request error (error code: C404H) in the device specified by (s3)+1.
• 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 dedicated instruction to the end of
execution.
• The intelligent function module device (buffer memory) is not affected by the sequence scan of the CPU module and
therefore can process protocols faster than assigning programmable controller devices to variables.
• If protocol setting data is written during execution of the GP.ECPRTCL instruction, the protocol in execution is canceled
upon completion of writing and the instruction is completed with a protocol setting data write error (error code: C430H).
• If the fixed buffer send/receive mode (such as send) of the specified connection has an invalid combination with the
communication type of the protocol to be executed (such as receive only) while the connection number of the Ethernet
module is one from 1 to 16, the GP.ECPRTCL instruction is completed with a connection number setting error (error code:
C407H).
• If the receive waiting time is set to "0: Infinite wait", the GP.ECPRTCL instruction is not completed until the data specified in
the protocol setting is received.
