Analog Output Module Configuration
Analog Output Module Control Byte
The Terminator I/O analog output modules are configured using the Module
Control Byte located in the most significant byte of the most significant word of
channel 1 of the module. The “I/O Memory Map and Analog Module Resolution”
chapter in the Terminator Installation and I/O Manual (T1K–INST–M) covers
memory mapping for the Terminator I/O modules.
