5 Setting Up EtherCAT Communications with the Sysmac Studio
Editing
OK Select Stop or Fail-soft operation for communications with all
slaves on the network when the master detects a communica-
tions error (cable disconnection, slave malfunction, etc.).
Default setting: Fail-soft operation
Refer to 9-1 Overview of Errors for details on errors.
OK Set the time to wait from the detection of the link on the Ether-
CAT port until all slaves join the network.
Setting range: 3 to 200 s
Default setting: 30 s
Process data communications start if all slaves are present
within the wait time. If all of the slaves are not present after the
wait time elapses, a Network Configuration Verification Error
occurs.
When you use a slave that takes time to start, use a longer wait
time setting to prevent errors.
OK A Process Data Reception Timeout error occurs if process data
(PDO) communications timeouts occur continuously more
often than the specified number of times.
Increase the setting if Process Data Reception Timeout errors
occur frequently, such as in high-noise environments.
Set the value to 2 or higher for a slave that needs to be
replaced.
Setting range: 1 to 8 errors
Default setting: 2 errors
OK Specify the method to use to verify the revision numbers that
are stored in the network configuration information (setting)
against the actual revision numbers of the slaves (actual
device) at the start of communications.
Communications will not start if there are unverified slaves,
and a Network Configuration Verification Error will occur.
Setting values: Setting <= Actual device, Setting = Actual
device, or No check
Default setting: Setting <= Actual device
*9 OK Specify whether to verify the slave serial numbers that are
stored in the network configuration information against the
serial numbers that are set in the actual slaves when initiating
communications.
Communications will not start if there are unverified slaves,
and a network configuration verification error will occur.
Setting values: Setting = Actual device or No check
Default setting: No check
*10 OK Specify whether to use the slave monitoring option during DC
Synchronous Correction which ensures sync jitter accuracy of
the DC time.
If Enable slave monitoring option is selected, the master exe-
cutes DC Synchronous Correction while monitoring the DC
time of the slave.
Use this setting if a Slave Application Error occurs when the
slaves are started. The error can be prevented if you select
Enable slave monitoring option and reconnect the slave. If the
error does not occur any more, that means a longer time is
required for the startup of all slaves and slave reconnection.
Setting range: Enable, or Disable slave monitoring option
Default setting: Disable slave monitoring option
