Pulse Output 2 Interrupt Feeding Error

What does A326.09 mean?

This flag activates if the Pulse Value (PV) for pulse output 2 experiences an overflow or underflow while an interrupt input is received, or during the execution of the IFEED(892) instruction when a specified number of pulses is being moved and the origin is defined. This indicates a data integrity issue within the pulse counter, specifically during interrupt-driven feeding operations where the PV limits are exceeded.

• PV overflow or underflow occurred during an interrupt input event while IFEED(892) instruction for pulse output 2 was active.
• PV overflow or underflow occurred while the specified number of pulses was being moved by the IFEED(892) instruction for pulse output 2, with the origin defined.
• The specified number of pulses in the IFEED(892) instruction for pulse output 2 was too large, causing the PV to exceed its 32-bit range.
• Conflicting or poorly timed interrupt inputs while the IFEED(892) instruction for pulse output 2 is running.

Click steps to track your progress.

1. 1

   Examine the ladder program logic related to the IFEED(892) instruction and associated interrupt inputs for pulse output 2.

2. 2

   Confirm that the specified number of pulses for the IFEED(892) instruction for pulse output 2 will not cause the PV to exceed the 32-bit range.

3. 3

   Analyze the timing of interrupt inputs relative to IFEED(892) execution for pulse output 2 to prevent concurrent actions leading to PV over/underflow.

4. 4

   Stop and then restart the IFEED(892) instruction processing for pulse output 2 to clear the flag.

5. 5

   Execute the INI(880) instruction for pulse output 2 to change (reset) its PV.

6. 6

   Toggle the Pulse Output 2 Reset Bit A542.00 from OFF to ON to clear the PV for pulse output 2 (documented on page 183).
