Result codes for SCLF instructions

When a tag is assigned to store the result of an
Equipment Sequence
 Clear Failure (SCLF) instruction, the instruction returns one of these codes when it executes.
Code (Dec)
Description
0
The command was successful.
48
The command was not executed because it was not possible at the time to generate an event to record the command.
  • If the command was an ABORT command, the ABORT command is still executed even if the event could not be generated.
  • This code only occurs if event generation has been enabled in the
    Equipment Sequence Properties - Configuration
     tab.
24578
The command is not valid for the current state of the
Equipment Sequence
. For example, if the
Equipment Sequence
 is stopped, then a stop command is not valid.
24594
The
Equipment Sequence
 is unscheduled, inhibited, or in a task that is inhibited.
Use the
Result
 operand to get a code that shows the success or failure of the SCLF instruction. The
Result
 operand should contain either
0
 or a DINT tag, depending on whether ownership conflicts or other errors are likely to occur.
  • If ownership conflicts or other errors are not likely, enter
    0
     in the
    Result
     operand.
  • If ownership conflicts or other errors are likely, enter a DINT tag in the
    Result
     operand. The DINT tag stores a code for the result of the execution of the instruction.
