Configure the 1769-BOOLEAN Module

The following I/O memory mapping lets you configure the 1769-BOOLEAN module.

Output Data File

For each module, slot x, word 0 in the output data file contains the control program’s directed

state of the module’s output points when operated in Direct Control mode. Direct Control

mode is active when an output’s disable BOOLEAN (DB_x) bit is set in the configuration

data file. Word 1 contains the control program’s directed states of the virtual inputs, which

can be used in controlling the module’s output points via BOOLEAN expressions.

Shaded bit positions must be set to 0.

OUTx = Output state in Direct Control mode; 1 = output on, 0 = output off.

Vx = Virtual inputs 0…7.

Input Data File

For each module, slot x, word 0 in the input data file contains the state of the module’s real

input points. Word 1 in the input data file contains the state of the module’s output data

(output data echo). During normal operation, this word represents the values that the outputs

are directed to by the control program (in Direct Control mode) or by the module (in

BOOLEAN Control mode).

Shaded bit positions must be set to 0.

INx = State of module’s real inputs 0…7.

Ox = Data echo of directed states of module outputs 0…3; 1 = output on, 0 = output off.
