# Allen Bradley 5380 Safety output 5069-OBV8S Circuit Fault

I recently encountered a red output light on my Allen Bradley 5380 safety digital output (5069-OBV8S) indicating a circuit fault. How can I program an alarm to notify the HMI when this occurs again?

To program an alarm to notify the HMI when a circuit fault occurs on your Allen Bradley 5380 Safety output (5069-OBV8S), you’ll need to follow these steps:

**Identify the Fault Condition:**

- Determine how the 5069-OBV8S module reports the circuit fault. Typically, this information is available through a status tag in the controller. **Create a Fault Monitoring Routine in the PLC:**
- Use the status tag associated with the 5069-OBV8S to monitor the fault condition in your PLC program. This might involve checking a specific bit that indicates a fault. **Set Up an Alarm Bit:**
- When the fault condition is detected, set an alarm bit in your PLC program. This bit will be used to trigger the HMI alarm.

**Configure the HMI Alarm:**

- Set up an alarm in your HMI software (e.g., FactoryTalk View) that monitors the alarm bit you set in the PLC.

Here’s a more detailed step-by-step process:

### Step 1: Identify the Fault Condition

**Check the Module Status Tags:**

- The 5069-OBV8S module has status tags that indicate various conditions, including faults. Refer to the module’s documentation to identify the specific tag and bit that indicates a circuit fault.

### Step 2: Create a Fault Monitoring Routine

**Open Your PLC Program:**

- In Studio 5000 Logix Designer, open the program for your 5380 controller. **Add a New Routine:**
- Create a new routine or use an existing one where you will monitor the fault status. **Monitor the Fault Bit:**
- Use a GSV (Get System Value) instruction or directly access the status tag to check for the fault condition. For example:

ladder configuration

```auto
GSV
    Class Name: Module
    Instance Name: "YourModuleName"
    Attribute Name: "FaultCode"
    Dest: FaultStatus

```

- If `FaultStatus` indicates a fault (non-zero), set an alarm bit:

ladder ladder configuration

```auto
XIC FaultStatus OTE AlarmBit

```

### Step 3: Set Up an Alarm Bit

**Define an Alarm Bit:**

- Create a new Boolean tag in your PLC program, e.g., `AlarmBit`. **Set the Alarm Bit:**
- In your fault monitoring logic, set this bit when a fault is detected.

ladder configuration

```auto
XIC FaultStatus OTE AlarmBit

```

### Step 4: Configure the HMI Alarm

**Open Your HMI Software:**

- Open FactoryTalk View Studio or your preferred HMI configuration software. **Create a New Alarm:**
- Go to the Alarm Setup section and create a new alarm. **Configure the Alarm to Monitor the Alarm Bit:**
- Set the trigger for the alarm to be the `AlarmBit` tag in your PLC. **Set Alarm Properties:**
- Define the message and any other properties for the alarm, such as priority and acknowledgment requirements.

### Example in FactoryTalk View:

**Add a New Alarm:**

- Go to Alarms and Events \> Alarm Setup \> Digital Alarms. **Define the Alarm Trigger:**
- In the Digital Alarm setup, set the trigger tag to `AlarmBit`. **Set Alarm Message:**
- Define the message that will be displayed on the HMI when the alarm is triggered, e.g., “Safety Output Circuit Fault Detected.” **Configure Alarm Properties:**
- Set the priority, category, and any acknowledgment settings as needed. By following these steps, you will have a system that monitors for circuit faults on your 5069-OBV8S module and triggers an alarm on the HMI when a fault is detected. This will help in promptly notifying operators and taking corrective actions.
