16 ETHERNET INSTRUCTIONS
16.5 Executing the Protocols Registered for the Predefined Protocol Support Function
• This instruction executes the protocol registered by the communication protocol support tool of the engineering tool for the
Ethernet module specified by (U). Using the connection specified by (s1), the instruction executes the protocol in
accordance with the control data stored in the device specified by (s3) and later.
• The instruction continuously executes as many protocols as specified by (s2) (a maximum of 8 protocols) at one time.
• The number of executed protocols is stored in the device specified by (s3)+0.
• The execution status and the completion status of the GP.ECPRTCL instruction can be checked with the completion device
(d) and the completion status indication device (d)+1.
• The following figure shows the operation at completion of the GP.ECPRTCL instruction.
+13 Receive packet number 4
successful in collation
match
If receiving is included in the communication type of the protocol that has been
executed fourth, the receive packet number successful in collation match is
stored.
If the communication type is "receive only", 0 is stored.
If an error occurs during execution of the fourth protocol, 0 is stored.
If the number of protocols executed is less than 4, 0 is stored.
0, 1 to 16 System
+14 Receive packet number 5
successful in collation
match
If receiving is included in the communication type of the protocol that has been
executed fifth, the receive packet number successful in collation match is
stored.
If the communication type is "receive only", 0 is stored.
If an error occurs during execution of the fifth protocol, 0 is stored.
If the number of protocols executed is less than 5, 0 is stored.
0, 1 to 16 System
+15 Receive packet number 6
successful in collation
match
If receiving is included in the communication type of the protocol that has been
executed sixth, the receive packet number successful in collation match is
stored.
If the communication type is "receive only", 0 is stored.
If an error occurs during execution of the sixth protocol, 0 is stored.
If the number of protocols executed is less than 6, 0 is stored.
0, 1 to 16 System
+16 Receive packet number 7
successful in collation
match
If receiving is included in the communication type of the protocol that has been
executed seventh, the receive packet number successful in collation match is
stored.
If the communication type is "receive only", 0 is stored.
If an error occurs during execution of the seventh protocol, 0 is stored.
If the number of protocols executed is less than 7, 0 is stored.
0, 1 to 16 System
+17 Receive packet number 8
successful in collation
match
If receiving is included in the communication type of the protocol that has been
executed eighth, the receive packet number successful in collation match is
stored.
If the communication type is "receive only", 0 is stored.
If an error occurs during execution of the eighth protocol, 0 is stored.
If the number of protocols executed is less than 8, 0 is stored.
0, 1 to 16 System
• Completion device (d)
This device turns on during END processing of the scan where the GP.ECPRTCL instruction completes, and turns off during the next END processing.
• Completion status indication device (d)+1
This device turns on or off depending on the completion status of the GP.ECPRTCL instruction.
When completed successfully: The device remains off.
When completed with an error: The device turns on during END processing of the scan where the GP.ECPRTCL instruction completes, and turns off during the
next END processing.
