• If you are using a Communication Digital I/O in Command Mode, refer to Command Words for
Command Mode.
A.3.4 Sending Data from the PLC
The method of sending data to the RMC from the PLC depends on the type of communication

A.3.5 Open Loop Using Profile Commands
Format: 0AAA RRRR 0000 NNNN
R Used for Status Area Request
N Used for Command Index described below
A Used only by Communication Digital I/O; 0 for PROFIBUS-DP
These commands allow the controller to tell the RMC100 to change the output drive to a specified
value with respect to null. The drive output will change at a rate specified by the select pre-stored
profile.
Note: This command shares the profile table used by the Go Using Profile commands. Profiles
used for one type of command should NOT be used for the other.
These commands behave identical to the Open Loop ASCII command, except that the specified
stored profile information is copied into the active Mode, Accel, Decel and Speed first. Recall that
the Speed field of the profile is not used by the Open Loop. Refer to that command for further
details.
The format of the Command Register for the Open Loop Using Profile commands is given below:
