Condition/State Action Taken
Prescan The .EN, .DN, .ER, and .IP bits are cleared to false.
Rung-condition-in is false The .EN bit is cleared to false if either the .DN or .ER bit is true.
Rung-condition-in is true The .EN bit is set to true and the instruction executes.

Extended Error Codes
Extended Error Codes provide additional instruction specific information for the
Error Codes that are generic to many instructions. Extended Error codes for the
Parameter Out of Range (13) error code lists a number that refers to the number
of the operand as they are listed in the faceplate from top to bottom with the first
operand being counted as zero. Therefore for the MCSV instruction, an extended
error code of 2 would refer to the Master Value operand’s value. You would then
have to check your value with the accepted range of values for the instruction. See
Motion Error Codes (.ERR) for Motion Instructions.
