DeviceLogix™ Functionality Chapter 12
Function Blocks The 193-DNCT has function blocks available in the DeviceLogix Library. The
DeviceLogix Library version 3 and 5 are available with firmware v2.001 and
v3.001, respectively. Devices that use the DeviceLogix Library version 3 or later
may enable support for an enable line on each function block. An upgrade to the
existing Boolean function block displays the enable line, if the device supports
this feature.
The 193-DNCT Series A v2.001 and later are able to display analog function
blocks. Each analog function block contains a
PARAM selection on it, which is
used to display and edit additional data that is specific to the type of function
block.
The available analog function blocks are:
• Arithmetic
• Alarm
• Compare
• Masked Compare
• Timing Diagnostic
• Limit
• Filter
• Select
• Average
Use the INC / DEC keys to assign a type to the new function block. Press the
Enter key when the desired type is selected. The screen should now display a new
function block of the selected type:
Note : At this time a new function block has been created and assigned a type, but
the inputs and outputs are not assigned at this time.
Assigning Source Bits to
Function Block Inputs To assign or edit input source bits for a function block, first choose the function
block input by pressing the
Sel key to scroll through the function block inputs.
With each successive Sel key press, a different input will be selected on the screen.
