Indexed Moves
All of the moves that have been explained in the chapter up to this point can be started by a transition on one
of the inputs instead of a command from the network. If the
Indexed Move bit is set when the command is
issued, the SV160E2 will not run the move until the configured input makes an inactive-to-active transition.
This allows you to run time critical moves that cannot be reliably started from the network because of mes-
saging time delays.

The input must be configured as a Start Indexed Move Input.

The move begins with an inactive-to-active transition on the input. Note that an active-to-inactive tran-
sition on the input will not stop the move.

The move command must stay in the Network Output Data while performing an Indexed Move. The
move will not occur if you reset the command word before the input triggers the move.

The move can be run multiple times. (The Command Bit for the move does not have to toggle between
moves.) Command data can be changed. For Jog and Registration Moves, the changes take effect
immediately. For all other moves, the changes are applied on the next move. The move is run on every
inactive-to-active transition on the physical input if a move is not currently in progress. Once a move is
triggered, the Start Indexed Move Input is ignored by the SV160E2 until the triggered move is finished.

A Jog Move that is started as an Indexed Move will come to a controlled stop when the command bit in
the Network Output Data is reset to zero.

It is possible to perform an indexed Jog Move by configuring two inputs for their respective functions.
The first input, configured as a
Start Indexed Move Input , starts the jog and the second, configured as a
Stop Jog or Registration Move Input causes the jog to end.

It is possible to perform an indexed Registration Move by configuring two inputs for their respective
functions. The first input, configured as a
Start Indexed Move Input , starts the move and the second,
configured as a Stop Jog or Registration Move Input causes the registration function to occur.

You cannot issue a Hold Command with the Indexed Bit set and have the Hold Command trigger on the
inactive-to-active transition of a physical input. Hold Commands are always acted upon as soon as they
are accepted from the Network Output Data.

You cannot issue an Immediate Stop Command with the Indexed Bit set and have the Immediate Stop
Command trigger on the inactive-to-active transition of a physical input. Immediate Stop Commands
are always acted upon as soon as they are accepted from the Network Output Data. If you need this
functionality, consider programming the physical input as an E-Stop Input.

You cannot issue a Clear Error Command with the Indexed Bit set and have the Clear Error Command
trigger on the inactive-to-active transition of a physical input. Clear Error Commands are always acted
upon as soon as they are accepted from the Network Output Data.
