Applied connection of EtherNet/IP communications
■When the RJ71EIP91 is the target
*1 A method to send data when the status changes. On the RJ71EIP91, data is sent when Application Trigger is requested.
*2 A method for communicating with a fixed size.
*3 A method for communicating with a variable size.
*4 A connection set from the RJ71EIP91 to the originator only for receiving data.
■When the RJ71EIP91 is the originator
*1 A method to send data when the status changes. On the RJ71EIP91, data is sent when Application Trigger is requested.
*2 A method for communicating with a fixed size.
*3 A method for communicating with a variable size.
*4 A connection simultaneously set from the RJ71EIP91 to the target for sending data and set from the target to the RJ71EIP91 for
receiving data.
*5 A connection set from the target to the RJ71EIP91 only for receiving data.
*6 A connection that monitors the data communication with the target to which a connection has been established.
*7 Connection requests can be set, but are sent from the RJ71EIP91 with a fixed size.
For the connection setting method, refer to the following.
