Reference response time
(Link scan time/timeout time
*1 The reference response time is the time it takes for the servo amplifier to receive a command from the master station and respond to the
master station.
*2 The link scan time is calculated by the following formula. Use the reference response time for Ns.
For MELSEC iQ-R/MELSEC-Q/L: Ls = Ns + Nm
For MELSEC iQ-F: Ls = SM + {(Ns + Nm)/SM}
Ls: Link scan time, Ns: Remote station response time, Nm: Master station request time, SM: Sequence scan time
*3 Check the current link scan time (when all remote stations are normal) with CC-Link IE Field Network Basic diagnostics, and set the
timeout time to about 5 times the link scan time (50 ms if the current link scan time is 10 ms).

Description
This function supports CC-Link IE Field Network Basic.
Network configuration settings are performed by using GX Works2,
GX Works3, and MR Configurator2.
This function supports SLMP (SeamLess Message Protocol).
Parameter settings and monitoring are available.
File for describing the necessary information for startup, operation,
and maintenance of CC-Link family connected products.
When the CPU module of the cyclic master is at STOP, when the
stop error occurs, Hold/Clear is automatically set on the refresh
device output. The servo amplifier stops regardless of the setting of
Hold/Clear of the cyclic master.
This is a function to reset a servo amplifier via the network. Servo
parameters to be enabled at power cycle are reflected by resetting
the servo amplifier.
IP addresses are delivered from the controller to servo amplifiers
via CC-Link IE Field Network Basic.
