Enable/Disable Logic
For logic to execute, it must be enabled. While editing online with RSNetWorx
for DeviceNet, you can enable logic.
Logic Enable On
Use the Logic Enable On function to notify the device to start processing the
stored logic diagram. To set Logic Enable On, select Communications > Logic
Enable On.
Logic Enable Off
Use the Logic Enable Off option to notify the device to stop executing the
logic program. When you select this option, the device enters an idle state,
turning off the Logic Enable Bit in the produced data. The Logic Enable bit in
the Produced I/O assembly of the device reflects a 0 or 1 for Logic Enable
Off or Logic Enable On. To set Logic Enable Off, select Communications >
Logic Enable Off.
Dependent Mode
Logic will also be enabled or disabled if the Dependent Mode parameter is
Enabled. In this case, logic will execute following the state of the owning
connection. When the connection is in RUN, the logic is enabled. When the
connection is in Idle, Fault, or non-existent, logic is disabled.
You can also enable or disable logic through explicit messages from the
owning controller. See Messaging
