If the reading of the sequence program is continued, the ladder
program being executed is automatically stopped.
NOTE
1 When the format of a specified file cannot be
recognized, the read operation is terminated
abnormally with the following message:
"UNKNOWN FILE FORMAT"
2 Sequence programs for the conventional model
cannot be read. If a sequence program for the
conventional model is read, the read operation is
terminated abnormally with the following message:
"LADDER TYPE UNMATCH"
WARNING
1 If a ladder program is read while another ladder
program is being executed, the ladder program
being executed is automatically stopped. Take
special care when stopping a ladder program. If a
ladder program is stopped at an inadequate timing
or in an inadequate machine state, the machine can
make an unexpected movement. Moreover, when
a ladder program is stopped, the safety feature and
monitoring based on the ladder program do not
function. Before stopping a ladder program, make
sure that the machine state is normal and that there
is no person near the machine.
2 When an attempt is made to stop the ladder
program being executed, the stop processing may
continue endlessly, depending on the ladder
operation. In such a case, modify the ladder
program according to Section 4.15.
