Module Data, Status, and Configuration 49
Program State
This configuration selection provides the individual selection for the control of
the module outputs when the system enters the program mode. Word 3, bits
0
… 3 are used to select the program state control mode for module outputs
OUT0 through OUT3. When any of these bits are cleared (0) and the system
enters the program mode, the module holds that output's last state, meaning
that the output remains at the last value prior to the condition that caused the
control system to enter the program mode.
When any of these bits are set (1) and the system enters the program mode, it
instructs the module to set the outputs to the corresponding user-specified
values from the configuration data file's Program Value word.
Program Value
Use the Program Value word to set the values for the outputs to assume when
the system enters the program mode and the Program State bit for any outputs
are set (1). Word 4, bits 0
…
3 indicate the values to apply to the corresponding
module outputs OUT0 through OUT3. A value of 0 in any bit will set the
corresponding output to the OFF state when the system enters program
mode. A value of 1 in any bit will set the corresponding output to the ON state
when the system enters the program mode. The default setting for the
Program Value word is 0 for all bits indicating that when applicable, all module
outputs should be set to the OFF state.
IMPORTANT
Hold last state is the default setting for the 1769-BOOLEAN
program state control bits.
TIP
The MicroLogix 1500 and CompactLogix controllers do not yet
support program state control. This functionality is currently
only supported when the module is used on the DeviceNet
network via the 1769-ADN adapter.
