Hysteresis value.

[AGorbatykh]

Hello.
I tried to set hysteresis to alert andler from script, like this:

Code: Select all

dpSetWait( dp+".Value:_alert_hdl.4._u_hyst_limit",(float) (Val1 - hyst),
            dp+".Value:_alert_hdl.3._u_hyst_limit", (float) (Val2 - hyst),
            dp+".Value:_alert_hdl.2._u_hyst_limit", (float) (Val3 - hyst),
            dp+".Value:_alert_hdl.1._u_hyst_limit", (float) (Val4 - hyst));

But I cannot set any float value, only integer. For example, when I use hyst = 1.8, I set 1, etc.

How can I set float values for hysteresis from script&

Please confirm that Val1, Val2, Val3, Val4 are of type float, or else hyst will be cast to int before performing the subtraction, and only afterwards to float.
Or you can try with:

Code: Select all

dpSetWait( dp+".Value:_alert_hdl.4._u_hyst_limit", ( (float) Val1 - hyst),
                dp+".Value:_alert_hdl.3._u_hyst_limit", ( (float) Val2 - hyst),
                dp+".Value:_alert_hdl.2._u_hyst_limit", ( (float) Val3 - hyst),
                dp+".Value:_alert_hdl.1._u_hyst_limit", ( (float) Val4 - hyst));
