3 ETHERNET INTERFACE MODULE REPLACEMENT
3 - 31
(2) Q series
[Open processing]
The Q series uses the dedicated instruction (OPEN) to perform open processing.
The communication parameters can be set using one of the following methods:
• In the control data of the dedicated instruction (OPEN)
• On GX Developer, select "Network parameter" - "Network Parameter Setting the Number of
Ethernet/CC IE/MELSECNET Cards" - (Ethernet) - "Open settings".
[Close processing]
The Q series performs close processing by either using the dedicated instruction (CLOSE), or by the
close request (FIN) from an external device.
(a) Program conditions
The following shows a program example for performing open processing (unpassive open) on
connection No.1 when initial normal end (X19) turns ON with the initial normal end signal (M5000)
ON.
Set the communication parameters in "Network parameters" on GX Developer.
(b) Network parameter setting example
1) "Open settings"
Point
When replacing the A/AnS series with the Q series, change the open processing/close processing
program of the A/AnS series to that of the Q series.
