Parameter CRC output number

4.2.6
(1) Overview
A CRC can be calculated from the parameter file storing the parameter settings for the safety monitoring functions
and sent out on dedicated output signals. Monitoring the signals enables peripheral devices to detect a change
in the safety monitoring function parameters.
(2) When is a CRC calculated?
A CRC of the parameter file is calculated:
• Immediately after the controller is powered on
• After a safety monitoring function parameter is changed and it is written in the controller
* Even if the safety monitoring functions are disabled, a CRC is calculated and sent to the dedicated output signals.
* When the parameter file is written to the controller with the RT ToolBox3 restoration function, a CRC is calculated
when the controller is power-cycled. The CRC becomes the same as one calculated when the written parameter
file is backed up.
4-22 Startup and Basic Configuration
During the recovery mode, the SLP function generates no errors even if the robot
intrudes into the restricted area. Take care not to let the robot interfere with peripheral
devices. Also, during the recovery mode, the safety monitoring functions are stopped
temporarily. Configure a safety system in such a way that the dedicated output signal
enables recognizing the recovery mode is active. The recovery mode disables the robot
from stopping at an operating area boundary. Take care not to move the robot toward
the outside of the operating area.
