8.6 Network Error Detector Suppression (Version 1.7 or later)
If facilities are powered up, the network components will immediately start to
establish connections between the master and slaves.
If connected as a slave, the robot controller will start to establish connection with the
master (PLC). The time required for the establishment will differ depending upon
manufacturers of masters.
Also if the robot controller RC5 equipped with DeviceNet master board is connected
as a master with RC5 slaves, then the time required for establishing connections will
vary depending upon differences between setting-up times of individual controllers.
If it takes long time to establish connection after the controller is turned on, then the
controller system may interpret it as a network error. To prevent such a network error
from occurring, Main Software Version 1.7 or later newly supports the network error
detector suppression that suppresses the detector for the specified time after the
controller is turned on.
You may set the suppression time length (from 0 to 65535 ms) to the "17: Insensitive
time to network error (ms)" parameter in the I/O Hardware Settings window (Access:
[F4 I/O]—[F6 Aux.]—[F1 Set H/W]).
The initial value of the parameter is 8000, meaning that no network error will be
detected for 8 seconds after completion of controller initialization.
If a network error occurs when the controller is turned on, then it will be detected 8
seconds later.
This parameter takes effect only immediately after the controller is turned on. After
that, it does not influence network error detection so that any network error will be
detected the moment it occurs.
