Invalid Program Number

Was bedeutet PGNO_FAULT ?

This fault occurs within the CELL.SRC program when the robot controller receives an invalid program number from a higher-level controller. The `P00` function call with `#PGNO_FAULT` signifies that the program number transmitted (e.g., via `#EXT_PGNO`) does not match any of the defined `CASE` branches in the `SWITCH PGNO` statement, preventing the selection and execution of a user-defined program.

• The program number entered or referenced by the control system is invalid.
• The specified NC program does not exist in memory or on storage.
• Program selection error due to incorrect program number format or nonexistent program.

1. 1

   Review the higher-level controller's logic to confirm it is sending a valid program number (e.g., 1, 2, 3 as per the example in CELL.SRC).

2. 2

   Inspect the `CELL.SRC` file to verify that the `SWITCH PGNO` statement includes `CASE` branches for all expected program numbers from the higher-level controller.

3. 3

   If new user programs are added, ensure corresponding `CASE` entries are created in `CELL.SRC` and that `P00 (#EXT_PGNO,#PGNO_ACKN,DMY[],0 )` is called after successful receipt.

4. 4

   Check the configuration of the `P00.DAT` file if error numbers are intended to be transmitted back to the higher-level controller (refer to Page 197 for details).
