• One programming tool can monitor or test local devices in one program at a time. Local devices in multiple
programs cannot be monitored or tested simultaneously.
• When local devices in a stand-by type program are monitored, data in local devices are saved and restored.
For this reason, the scan time increases.
• When local devices in a fixed scan execution type program are monitored, data in local devices cannot be
acquired and "0" is displayed.
