+0 Registration/delete
specification
Specifies whether to register or delete the user frame specified by (s1)+2.
• 1: Registered
• 3: Deleted
1, 3 User
+1 Registration/delete
result
Used to store the result of registration or deletion with the G(P).PUTE instruction.
•0: Normal
• Other than 0: Error (error code)
 System
+2 Frame number Specifies the user frame number. 1000 to 1199 User
+3 Number of registered
bytes
• 1 to 80: Number of bytes of the user frame to be registered
To delete the user frame, specify a value from 1 to 80 as the dummy.
1 to 80 User
• To register a user frame, specify 1 for the device of (s1)+0. The data in the device specified by (s2) and later will be registered according to the control data.
• The registered data must be stored as follows in the device specified by (s2) and later. Each of the devices to store the registered data requires the data for
the following number of points from the device specified by (s2): (amount of registered data)/2.
• To delete a user frame, specify "3" for the device of (s1)+0. The user frame with the frame number specified by (s1)+2 will be deleted.
• Both the number of registered bytes specified by (s1)+3 and the registered data storage device are required for the G(P).PUTE instruction format although
they are not used by the G(P).PUTE instruction. Specify a value from 1 to 80 for (s1)+3. Specify a dummy device for (s2).
• Completion device (d)
This device turns on during END processing of the scan where the G(P).PUTE 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 G(P).PUTE 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 G(P).PUTE instruction completes, and turns off during the
next END processing.
