Active State (prior to V2.04.x)
The attribute "Active State" defines when a digital input/output is active.
NOTE: The "Active State" attribute does not reflect the current condition of a digital datapoint.
NOTE: This is not applicable to digital inputs in applications designed for con- trollers using V2.04.xx firmware or higher. In such applications, this attribute is fixed at 1, and the new attribute "Normally Open/Normally Closed" (NO/NC) is active (see section "Normally Open/Normally Closed (V2.04.xx or higher)" on page 28 for more details).
The following values are possible:
•0 = digital input/output is active when a "logical 0 signal" is present
•1 = digital input/output is active when a "logical 1 signal" is present
Table 3 indicates the active state for various conditions of the XF523 and XFL523 modules.
