EtherNet/IP communication control
■EtherNet/IP communication start request (Un\G7340096)
Set a value other than 0 to make a request to start the EtherNet/IP communications.
• Other than 0: EtherNet/IP communication start request
• 0: EtherNet/IP communication stop request
To start EtherNet/IP communications by setting a value other than 0 for 'EtherNet/IP communication start
request (Un\G7340096)', set all 'Class1 cyclic pause specification' (Un\G7735808 to Un\G7735823) to 0.
When 'Class1 cyclic pause specification' (Un\G7735808 to Un\G7735823) is not all set to 0, EtherNet/IP
communications will not start even if a value other than 0 is set for 'EtherNet/IP communication start request'
(Un\G7340096).
In this case, 2 (cannot start) is stored for 'EtherNet/IP communication start status' (Un\G7340097).
The following figure shows the timing chart for 'EtherNet/IP communication start request' (Un\G7340096).
