Setting
■Connecting between ports where the fast link-up function is enabled
Enable the fast link-up function for both P1 and P2.
If a port where the fast link-up function is enabled is connected with a port where the fast link-up function is not supported or is
disabled, link-up is not performed.
Installation and structure
■Incorporating a master module and an I/O module in the robot-side system
Incorporate a master module and an I/O module in the robot-side system.
Use one of the modules described below as the master module.
Page 67 Applicable master station
Disable the fast link-up function for a port of the I/O module that is to be connected to the master module.
■Connect P1 and P2.
Between the modules where data link is established using the fast link-up function, connect P1 and P2 with cables.
Even if the fast link-up function is enabled, link-up will not be performed when P1 is connected to P1 or P2 is connected to P2.
■Enabling the fast link-up function for P2 of the I/O module in the robot-side system
Disable the fast link-up function for P1 of the I/O module in the robot-side system, and connect it with the master module.
Enable the fast link-up function for P2 of the I/O module in the robot-side system, and connect it with an I/O module in the tool-
side system.
For any other connection, it may take longer time to establish data link.
Operation
■Keeping the modules in the robot-side system always powered on
Always keep the master module and I/O module in the robot-side system powered on during operation.
In the robot-side system, the master module is connected with the I/O module via a port where the fast link-up function is
disabled, and thus the time taken to establish data link after power-on will not be shortened.
■Simultaneously powering on all of the I/O modules in the tool-side system
To connect using fast link-up, simultaneously power on all of the I/O modules in the tool-side system after switching a tool to a
different one.
If the I/O modules are powered on at different times, it may take longer time to establish data link.
■Connecting to a different tool in one second after the master station detects a disconnection
of a tool previously used
Connect to a tool (cable connection and power-on) in one second or longer after the master station detects a disconnection of
a tool previously used.
If a tool is connected before a detection of a disconnection or within one second after the detection, it may take longer time to
establish data link.
A disconnection can be detected by monitoring Data link status (each station) (SW00B0 to SW00B7) of the master station.
Precautions
• After the master station is powered on, it may take longer time to establish data link with each I/O module at the first
connection.
• Depending on the operating environment, it may take longer time to establish data link.
• If the link scan time when no tool is connected is long, it may take longer time to establish data link.
• On the network configuration settings, set line topology for the network topology.
