Install a 1734-TOPS Base
1. Position the base vertically above the installed units, such as an
adapter, power supply, or existing module.
2. Slide the base down, allowing the interlocking side pieces to engage
the adjacent installed unit.
3. Press firmly to seat the base on the DIN rail until the base snaps into
place.
4. Verify that the DIN-rail locking screw is in a horizontal, locked
position before inserting an I/O module.
Remove a 1734-TOPS Base
To remove a wiring base from the DIN rail, you must remove the module
installed to the right of the base.
1. Squeeze the module locking mechanism of the module to the right of
the base, pulling up to remove the module.
2. Turn the orange locking screw to a vertical position to unlock the base
from the DIN rail.
3. Slide the base up to release it from its mating units.
Communicating with Your Module
I/O messages are sent to (consumed) and received from (produced) the
POINT I/O modules. These messages are mapped into the processor’s
memory. This POINT I/O input module produces 24 bytes of input data
(scanner Rx) and fault status data. It does not consume I/O data
(scanner Tx).
