1.9.5 Adding an Ethernet/IP Adapter
1.9.5 Adding an Ethernet/IP Adapter
EtherNet/IP data is referred to as an Instance. Each device
manufacturer defines the type of data contained and the instances
supported. Refer to the specific adapter documentation for details
regarding successful communication.
•
The MPiec controllers can communicate with up to 20 unique IP
addresses simultaneously using the EtherNet/IP protocol.
• Explicit Messaging is supported by using the Explict_Message
function block provided in the Yaskawa Toolbox v202 or
higher. Explicit Messaging does not require setup in the Hardware
Configuration.
• The minimum poll period or update interval is 2 ms. (Note that
EtherNet/IP is not a deterministic protocol. Setting a very fast
update interval is not recommended because it will increase the
load on the CPU. Fast updates and high priorities should be
allocated based on application requirements.)
