QuickConnect system guidelines
The following guidelines are required in order to enable setup with QuickConnect:
Tool side devices
• Use a preconfigured, static IP address for the devices. This removes
DHCP/BOOTP cycle time.
• Configure the devices for 100 Mbps, full-duplex operation in both the
switch and the end-node device.
• Configure the devices to not autonegotiate and to not use Auto-MDIX.
• Use straight-through EtherNet/IP cables on the devices.
• Connect the devices in a linear topology. Ring topology is not supported.
Switches
• Make sure an EtherNet/IP managed switch on the controller side re-
mains powered on at all times. Only the tool side is subject to power cy-
cling. This is important so that the switch does not block communication
to and from devices.
Data
• I/O data sizes must remain the same when nodes on a new device use
the same IP address. If the I/O sizes are different, then the nodes need
unique IP addresses.
Communication
• A QuickConnect I/O device issues a gratuitous ARP message announc-
ing its presence on the network. The module continues to issue the gra-
tuitous ARP message every 25 ms for a maximum of 40 times
(1 second) until an I/O connection is established.
• The module issues a TCP close when it receives a forward close mes-
sage. Otherwise, connections may stay open for several seconds before
they time out.
Controllers
• Upon receiving the electrical lock signal, the controller waits for a mod-
ule-specific delay period and then uninhibits the QuickConnect module
to open an I/O connection.
•
The controller knows the device startup time. You might need to alter the
power-up time to delay the connection establishment procedure by that
amount of time.
