Unit Output Pattern
Both in Range and Comparison Mode the 32 Outputs of the Unit are represented
by the Unit Output Pattern. The Unit uses the Unit Output Pattern internally to con-
trol the Outputs. The Unit Output Pattern consists of 28 Soft Outputs and 4 Digital
Outputs. The four Digital Outputs represent the Physical Outputs O0, O1, O2 and
O3 of the Unit.
Output Status
The status of the Digital Outputs is reflected by their corresponding bits in CIO and
can be used as event flags in the Ladder Program. The Soft Outputs for instance
can be used in the Ladder Program to control outputs of an external Digital Output
Unit.
Note
Every Soft and Digital Output can be configured to generate an Interrupt to the
CPU. For details refer to
4-6-1 "Outputs Generating Interrupts".
