Module Configuration for BX-04DA-3, BX-08DA-3 Universal Current / Voltage Output Modules
When a Do-more CPU powers up and detects a new BX-04DA-3 or BX-08DA-3 module it will automatically create a module configuration and assign the required I/O mapping using the first 4 or 8 available WY (32-bit signed integer) locations required by the module.
The default configuration has all of the channels enabled in 0 - 5V mode with scaling disabled. Clicking the Edit Config button in the Module Configuration utility will open the following dialog where the default configuration can be changed.
The Analog Outputs 0-3 and Analog Outputs 4-7 (if available) tabs set the following options that are specific to the individual channels:
Analog Output # (voltage) 0 - 5V, 0 - 10V, +/- 5V, +/- 10V, (current) 4 - 20mA or +/- 20mA.
The WY# shows the range of values, the resolution, and the units / count of the raw output based on the current Analog Output # selection. The range for bipolar voltage and current selections is -32768 to +32767; the range for unipolar voltage selections is 0 - 32767; the range for the unipolar current selection is 6553 - 32767.
The RY# group (if automatic scaling is enabled for this channel) shows the Real numeric memory location where the engineering unit value is stored in the CPU, the range of potential values and the Units / Count based on the current scale factors.
Enable Scaling from RY# to WY# enables the automatic scaling of the engineering units (32-bit real) to raw output value (32-bit signed integer).
RY# Min / RY# Max contains the minimum and maximum values for the engineering units.
WY# Min / WY# Max the minimum and maximum raw values determined by the Analog Output # selection.
Counts / (mA or VDC) displays the WX#'s Min and Max values in terms of counts or milliamps / volts depending on the Analog Output selection type.
Clamp WY# (if enabled) and the calculated scaled value is lower than WY # Min or higher than WY# Max, the specified Min and Max values will be used.
