Module Status Indicators
The module features several LED indicators to provide real-time information on the module’s operational status and potential issues. These LEDs help with troubleshooting and monitoring the performance of the module. Below are the descriptions of each LED and their corresponding indicators:
- Module OK LED
- ON Green: Indicates that the module is functioning correctly and is properly configured.
- Slow Flashing Green or Amber: Indicates that the module is operational but has not been configured.
- Quick Flashing Green: Indicates an error in the module.
- OFF: Indicates that the module is defective or that no backplane power is present.
- Field Status LED
- ON Green: No faults are detected on any enabled channels, and the Terminal Block (TB) is present.
- ON Yellow: Indicates that there is a fault on at least one channel.
- OFF: The terminal block is not present or is not properly seated.
- TB (Terminal Block) LED
- ON Red: The terminal block is either not present or not properly seated.
- ON Green: The terminal block is present and correctly seated.
- OFF: There is no backplane power supplied to the module.
Input Scaling
- Input Scaling in the module is a crucial feature that enables the module to convert analog inputs, such as voltage or current, into a floating-point value that can be processed by the PLC (Programmable Logic Controller). By default, the module operates over the entire span of its configured range, converting the input into a value that reflects the raw signal. For instance, if the configured range is 4 to 20 mA, the module will output values from 4.000 to 20.000. This allows the PLC to interpret the input as a usable, standardized value.
- Scaling in the module can be adjusted by modifying the Low Scale and High Scale Value parameters. These four channel scaling parameters allow you to change the scaling to better suit the specific needs of your application. This is especially useful when you need to convert input values into more meaningful Engineering Units, such as temperature, pressure, or flow rate. By customizing the scaling, you can tailor the module to convert raw sensor signals into units that are more useful or interpretable by the system.
- The scaling process is linear, meaning that the relationship between the input signal and the scaled output is constant and predictable. However, the system also supports inverse scaling, where the scaling can be reversed, mapping high input values to low scaled values or vice versa. This flexibility allows you to match the system's behavior to the unique requirements of the application, offering better control over the inputs.
- Alarm values in the module are always applied to the scaled Engineering Units rather than the raw input values. This ensures that alarms reflect real-world conditions and are based on the final interpreted values. By scaling input values into Engineering Units, the system provides more meaningful and actionable alarm signals, ensuring that any issues are promptly identified in terms that are relevant to the physical process.
- The scaling parameters are designed to define a linear relationship between the raw input and the scaled output but do not have to match the full range of the sensor input. This flexibility allows you to configure the scaling to suit particular needs, enabling more customized applications without being restricted to the sensor’s native range. Whether you need to scale to a narrower range or adapt to specific system requirements, the module can be easily configured for various scenarios.
