EtherNet/IP data link continuation specification
■EtherNet/IP data link continuation specification request (Un\G16634)
This address is used to set whether to continue EtherNet/IP communications when 'EtherNet/IP communication start request'
(Y10) is turned on and off.
Set this address to continue EtherNet/IP communications in situations such as when the CPU module changes from the RUN
state to the STOP state and when a stop error occurs on the CPU module.
The setting is reflected when 'EtherNet/IP communication start request' (Y10) is turned off and on.
• 0: Stops EtherNet/IP communications.
• 16: Continues EtherNet/IP communications.
■EtherNet/IP data link continuation specification state (Un\G16635)
This address is used to store the setting status of 'EtherNet/IP data link continuation specification request' (Un\G16634).
The setting is reflected when 'EtherNet/IP communication start request' (Y10) is turned off and on.
• 0: The 'EtherNet/IP data link continuation specification request' (Un\G16634) setting has not been reflected.
• 1: Operation is in progress with the setting for continuing EtherNet/IP communications.
• 2: Operation is in progress with the setting for stopping EtherNet/IP communications.
Class1 I/O data size
■Class1 Input data length (Un\G16640 to Un\G16895)
This address is used to store the size of the data received by the RJ71EIP91 from the EtherNet/IP device during Class1
communications. (Unit: words)
■Class1 Output data length (Un\G16896 to Un\G17151)
This address is used to store the size of the data to send to the EtherNet/IP device from the RJ71EIP91 during Class1
communications. (Unit: words)
Setting status
