Wire Size and Terminal Screw Torque
Each terminal accepts two wires with the following restrictions.
Configure the 1769-OF4 Module
The following I/O memory mapping lets you configure the 1769-OF4 module.
Output Data File
For each module, slot x, words 0…3 in the output data file contain the control
program’s directed state of the module’s analog output channels. Word 4 contains
the cancel output-channel-clamp alarm control bits.
The bits are defined as follows:
•
SGN = Sign bit in 2’s complement format.
•
NU = Not used. Bit must be set to 0.
•
CHOx = Cancel High Clamp Alarm Latch for Output x: Allows each output
high-clamp-alarm latch to be individually cancelled. NOTE: Cancel = 1.
•
CLOx = Cancel Low Clamp Alarm Latch for Output x: Allows each output
low-clamp-alarm-latch to be individually cancelled. NOTE: Cancel = 1.
