Additional Information
• Depending on the actual operating environment, the transmission time may be longer than the
one calculated with the equations given here. The following factors can cause longer transmis-
sion times: other traffic on the network, window sizes of network nodes, other traffic at the
built-in EtherNet/ IP port itself (e.g., simultaneous tag data link communications), and the sys-
tem configuration.
• CIP communications processing is executed as a system service. If a timeout occurs for a CIP
communications instruction, reconsider the execution time for system services.
