[SFCP. OPE. ERROR]
The START instruction in an SFC program is
preceded by an END instruction.
■Collateral information
• Common information: Program error location
• Individual information: -
■Diagnostic timing
• When instruction executed
Read common information of the error using
the programming tool to identify the numeric
value (program error location). Check the
error step corresponding to the value, and
correct it as necessary.
