Configuration Tab - 1794-OF4I
Use this tab to configure each channel of your analog input module.
Parameters
Voltage/Current Range
This feature allows you to configure individual input channels to operate with a specific voltage or current range. There are four formats in which data is exchanged between the module and the adapter. The formats correspond to specific voltage/current ranges. The default value is 4 to 20mA-Signed Two’s Complement.
Hold For Initialization
This feature applies to the 1794-OF4I module only. By default, this feature is disabled and the check box is unchecked. Check this check box to enable this feature and to define the course of action to be taken for recovery from a communication fault or idle period. If you use this feature, when the module changes from Communication Fault or Program mode to Running mode, the output signal from the module does not change from its Safe State value until the real time output value (from the controller) matches the actual analog output read back value from the module.
TIP:
For FLEX I/O Combo modules and some output modules, in order for this feature to take effect, the enable member in the module’s output tag from the controller must be set to 1 using the Data Monitor from the Controller Tags window, or by using your own program.
Interleave Module Interrupts
Do not check the Interleave Module Interrupts check box unless you know you have a specific use for this option. The Interleave Module Interrupts feature is useful only in limited circumstances and can only be enabled when you configured a module’s Conversion Rate to 1200 Hz, Low Pass Time Constant to None, and Real Time Sampling period to 0 for ALL channels on the module.

If:
- you are online in Program, Remote Program or Remote Run mode and,
- this controller is the owner controller and,controllerA device that controls machines or processes elements (for example, a programmable controller or relay panel).
- you have changed the module’s configuration in the software,
when you click the Apply or the OK button, the information is automatically sent to the controller. The controller tries to send the information to the module (if the connection to the module is not inhibited). If you don’t click the Apply or OK button, your changes are not sent to the controller.
TIP:
The connection to a FLEX I/O module using Rack communication cannot be inhibited. The ‘Inhibit’ check box on the Connection tab is disabled in this case.
