Precautions for Safe Use
The header flashes in red if there is any difference between a ladder program retained by the
HMI and another one retained by the device. Use the Sysmac Studio to update the ladder pro-
gram in the HMI immediately. Note that it takes around one minute for differences to be
detected after changing a ladder program on the device.
The Ladder Monitor will continue operation in this state, but that may result in the false judg-
ment of the system status based on the incorrect information being provided from the displayed
ladder program that is different from that of the device. If you will use the Ladder Monitor while
the header is flashing in red, consider the information to be incomplete and perform operation
to secure the safety of the system. Furthermore, various functions such as power flow and
value modification may not work properly under this condition.
