13.6 Communication Fault/Idle Mode Parameter
This parameter is used to describe characteristics or behaviors of output points (bits). The parameter shown below is used to
determine what state the outputs will have, during an “Idle” event and a “Fault” event. The Communication Fault/Idle Mode
parameter will allow control of all output points on the manifold.
The user, through web page or graphic display settings, can determine how the outputs behave when a
communication fault or idle actions occurs. These settings are non-volatile and thus will not change upon loss of
power.
The two behavior options are:
1. Hold Last State
2. Turn Off All Outputs
The Communication Fault/Idle Mode parameter determines the output state if the device encounters a communication
fault and/or idle action. A Communication Fault is defined as an inability for the master node to communicate with a
slave node on a network. Idle Mode is a condition when the processor is in program mode.
The process for determining the output state during a Communication Fault/Idle Mode is as follows:
1. The device receives a Communication Fault/Idle Mode event.
2. The device determines what action to take based on the Communication Fault/Idle Mode attribute setting.
3. If the attribute is set to turn off all outputs, all of the outputs will turn off (Factory Default Setting).
4. If the attribute is set to hold last state, all of the outputs will hold their last state.
