Invalid Block #

What does 14 mean?

This error indicates that a jump or branch command within the CLM01.3-M user program is attempting to direct program execution to a block number greater than 999, which is outside the valid range for program blocks.

• A jump or branch command in the user program specifies a target block number exceeding 999.
• Typographical error during program entry, leading to an incorrect, out-of-range block number.
• Logical error in the user program causing an unintended jump to an invalid block.
• Parameter 84 (Start Task 2 & 3) is enabled with an invalid program block location.

Click steps to track your progress.

1. 1

   Review the CLM01.3-M user program to identify any jump or branch commands (e.g., JMP, JSR) that specify a target block number greater than 999.

2. 2

   Correct the target block numbers in the user program to be within the valid range of 000-999.

3. 3

   If Task 3 is being used, ensure that the Task 3 program is located within a valid program block range as specified in Parameter 84.

4. 4

   Re-test the program after corrections to ensure all jumps and branches execute to valid program blocks.

5. 5

   Perform a thorough debug of the program logic, especially for conditional jumps, to prevent accidental jumps to invalid addresses.
