Ethernet
*1 EtherNet/IP communication specifications are available only within the specifications of the communication destination.
*2 The total number of connections for Class1 communications, UCMM tag communications (server function), and Class3 communications
is 256.
Therefore, the number of each connection varies depending on the number and size of separate communications.
*3 If the external device does not support Large Forward Open (CIP option specifications), the communication data size is up to 504 bytes.
*4 The maximum number of simultaneous executions (the number of connections that can be received simultaneously) for the server
function is 96 for the total of UCMM and Class3 communications server functions.
*5 The communication speed of 100Mbps is recommended.
