Tag Group
Function
Machine mode
Additional modes can be added to the machine. By default, these are the included
modes:
• OPERATOR or Manual mode
• PROGRAM or Auto mode
Machine commands
Broadcast machine commands that direct all of the dependent modules (for
example, application and device modules).
Current machine state
Indicates the current state of the overall machine. Only one state can set at even
given time.
Previous machine state
Indicates the previous machine state. Used primarily by the application and device
modules to determine Transitional State faults.
Machine state display
String tag that can be used to indicate the current machine state.
Machine status
Indicates miscellaneous machine status information.
