Appendix D Function Blocks Command Reference
The Output Enable signal turns on if the Reset signal is correctly received while
the Monitored Input condition to the Reset function block is on. This function
block can be used to prevent the machine from automatically resetting when
power to the controller is turned on, when the operating mode is changed from
Idle mode to Run mode, or when a signal from a safety input device turns on.
The Static Release and Reset 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.
Reset Function Block Parameters
You can set the Reset signal for either Low-High-Low or Rising Edge by using the
Parameter tab of the Function Block Properties dialog box. The default setting is
Low-High-Low.
When configured for Low-High-Low, the Reset signal must meet the following
conditions.
Table 8 - Conditions for Outputs Turning On
