Appendix D Function Blocks Command Reference
The Output Enable signal turns on if the Restart signal is correctly received while
the Monitored Input condition to the Restart function block is on. This function
block can be used to prevent the machine from automatically restarting when the
power to the controller is turned on, when the operating mode is changed, or
when a signal from a safety input device turns on. Reset and Restart are
functionally identical.
The Static Release and Restart Required Indication are optional outputs. To
enable either of these outputs, check the checkbox on the Out point tab of the
Function Block Properties dialog box.
Restart Function Block Parameters
You can set the Restart signal for either Low-High-Low or Rising Edge on the
Parameter tab of the Function Block Properties dialog box. The default setting is
Low-High-Low.
When configured for Low-High-Low, the Restart signal must meet the following
conditions.
Table 9 - Conditions for Outputs Turning On
Output Condition for Turn-on
Output Enable The Monitored Input and all enabled optional inputs must be on, and
the Restart signal must be received correctly.
Static Release The Monitored Input and all enabled optional inputs must be on.
Restart Required Indication The Restart Required Indication becomes a 1 Hz pulse output if the
Monitored Input and all enabled optional inputs are on, and the Output
Enable signal is off.
The Restart Required Indication turns on only when the Restart signal is
on.
