Using the Controller as a Point Extension Device
If the controller is used only as a point extension device, with no control application in
effect, its application must be set to slave mode and the points must be unbundled at
the field panel. All of these points must be controlled from the field panel in order to be
used. See the
Point Database for more information.
NOTE:
DO 1 and DO 2 are wired internally. They can only be used to rotate a shaft that fits
into the ATEC through 90° or less.
NOTE:
If using either a motor or DOs as auxiliary points, be sure to set MTR SETUP to the
correct value. If using a pair of DOs to control a motor, the DOs cannot be unbundled
or commanded separately. Only MTR1 COMD can be unbundled to control the
motors.
Example
If using DO 1 and DO 2 as the physical terminations for a direct acting motor, follow
these steps:
1. Set MTR SETUP to 1 to enable the motor.
2. Unbundle MTR1 COMD (DMPR COMD) at the field panel to command the motor
from the field panel.
NOTE:
If more than one Motor must be set up, contact your local Siemens Industry
representative for more information.
