160 Function Blocks Command Reference
The number of inputs can be increased from two to eight on the I/O
Settings tab of the Function Block Properties dialog in RSNetWorx for
DeviceNet software. The default number of inputs is two.
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.
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. The
default setting is Low-High-Low.
When configured for Low-High-Low, the Restart signal must meet the
following conditions.
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.
