Module Control Byte
Analog output modules have a Module Control Byte that is used to configure some options
for the outputs. In the module addressing, this byte shows up as eight Discrete Output (Y)
Bits.
• Y0 = Outputs Enabled
• Y(0+1) = Unipolar/Bipolar
• Y(0+2) = 5V/10V Range
• Y(0+3) = 0–20mA/4–20mA
• Y((0+4) through (0+7)) = Reserved
When an analog output module is added to a Do-more project, a Module Configuration
with default Module Control Byte values is created. Its settings can be changed under
Module Configuration by double-clicking the Module Name or by selecting the New Config
or Edit Config buttons on the right hand side.
The Do-more T1H Series CPU will write the settings from the Module Configuration into
the modules before going to Run mode. The Y Bits can optionally be used to change the
Module Control Byte setting within the program.
