NORMAL do not override the feedback timer
SIMULATION MODE Field
This field facilitates testing and simulating device situations with TCL or a host
computer. When the Simulation Mode is ON, the device loop does not perform
inputs and outputs. When it is OFF, inputs and outputs are handled in the normal
manner.
This field defines the initial value of the Simulation Mode. During runtime, you can
turn the mode ON or OFF via the Loop/FCM Display for the device loop. You can
also change the mode by TCL or by programs run on a host computer.
The effect of the Simulation Mode on device processing depends on the state of the
DEVICE OVERRIDE field on the Device Loops Templet.
Valid entries are:
ON device simulation mode is on
OFF device simulation mode is off
INITIAL MODE Field
This field determines the output mode for the loop at the start-up.
Valid entries are:
AUTO loop is under the control of TCL or a supervisory package
MAN operator determines output
INITIAL COMMAND Field
This field specifies the command sent to the device upon start-up and the warmstart
action.
Valid entries are:
• any of the valid commands defined by the descriptor set for the device
• no entry (blank field) sends out a 0 when the device loop goes on-line
• NO COMMAND sends out nothing, that is, there is no processing on start-up.
