Rockwell Automation MD65 EtherNet/IP Communication Module - Manual (Page 88)

8-24 EtherNet/IP Communications Module
8.8 Additional Information
• When the MD65 with the MDCOMM-ENET module (Drive 0) is
powered up, all configured daisy-chained drives must be present
before an I/O connection is allowed on EtherNet/IP (i.e. before the
drives can be controlled).
• If the MD65 with the MDCOMM-ENET module (Drive 0) is
powered down, communications with the four daisy-chained
drives (Drive 1 to Drive 4) are disrupted and the drives will take
their corresponding Comm Loss Actions.
• If any of the daisy-chained drives (Drive 1 to Drive 4) are powered
down, the respective Input Image (Logic Status and Feedback)
sent to the scanner will be zeros, and the NET A and DRIVE
LEDs on the MDCOMM-ENET module will flash red. Status
information from the scanner will not indicate there is a fault at the
node, and the I/O connection will not be dropped.
