„Setting User Level

PLC can set the user level of using HMI from Bit 8, Bit 9 and Bit 10. The setting level is from level 0 to level 7. For example, when set Bit 8 to be ON, the user level is 1; when set Bit 9 to be ON, the user level is 2 and vise versa.

MSB (Most Significant Bit): Bit 10.

LSB (Least Significant Bit): Bit 8.

„Curve Sampling Control Flag (1-4)

HMI provides four curve sampling flags and four curve clear flags. HMI curve (general trend graph or X- Y chart) sampling is controlled by PLC. When this control flag is triggered to ON (Bit 0 ~ Bit 3 is set to ON), HMI will sample ONCE by reading continuous data of curve on HMI screen and convert the data to graph and show on HMI screen. Since the flag is only used to trigger the graphs and charts to be displayed or cleared, the same one flag can be used repeatedly for other trend graphs or X-Y charts. This flag needs be set to OFF and then ON if the user wants to trigger again.

„Curve Clear Control Flag (1-4)

Clear HMI curve (general trend graph or X-Y chart) when this control flag is triggered (Bit 8 ~ Bit 11 is set to ON). This flag needs be set to OFF and then ON if the user wants to trigger again.

„Register for Sampling History Buffer (HBSR)

For the settings of sampling history buffer, the user can refer to the description of “History Setup” in Chapter

2.HMI provides 12 records for tracking sampling register of history buffer. Besides, HMI time interval settings, sampling or clearing history buffer can be controlled via PLC.
