Auxiliary Commands (continued)

hý

Enter Read Status Mode -

This command puts the module in read status mode.

While in this mode, the module will transmit parameter values instead of position

and tachometer data. Four additional commands are enabled while in this mode that

allow you to specify which parameter values are to be read back.

hý

Exit Read Status Mode -

This command places the module back into its normal

mode of operation. Position and tachometer data will be transmitted after this

command is accepted.

Read Status Mode

This special mode of operation allows you to read back the transducer setup

parameter values. Position and tachometer data is not transmitted while in this

mode.

Because the block transfer read length from a 1700 module is fixed, it is not to read back all

of the parameter values with a single block transfer. For this reason, four additional commands

are enabled while in this mode. These commands allow you to specify which parameters are to

be read back. Once specified, the parameter values will be transmitted with every block

transfer read until new parameters are specified or you exit read status mode.

For more information on read status mode, refer to Chapter 6, Backplane Programming.
