SET_TOT
Setting this parameter to Reset assigns a value of 0 to the totalizer.
When set to Preset, the value of parameter PRESET_TOT is assigned to the totalizer.
While SET_TOT is set to Reset or Preset, the status of the totalized value is set to
UNCERTAIN-initial value.

MODE_TOT
Governs the behavior of the totalizer.
In Balanced mode, totalization occurs for all incoming rate values.
In Positive Only mode, totalization occurs for positive incoming rate values only.
For Negative Only mode, totalization occurs for negative incoming rate values only.
In Hold mode, totalization is stopped.

FAIL_TOT
Governs the behavior of the Function Block during the occurrence of input values with
BAD status.
In Run mode, totalization is continued using the input values despite the BAD status. The
status is ignored.
For Hold mode, totalization is stopped during occurrence of BAD status of incoming
values.
In Memory mode, totalization is continued based on the last incoming value with GOOD
status before the first occurrence of BAD status.

ALARM_HYS
Hysteresis value applied to block parameters HI_HI_LIM, HI_LIM, LO_LIM and
LO_LO_LIM. The hysteresis is expressed as value below high limit and above low limit in
the engineering unit of xx_LIM.

HI_HI_LIM
Upper limit value for alarms with the same engineering unit as that of the OUT parameter.
If the measured variable is equal to or higher than the upper limit value, the State Bits in
the Status Byte of OUT and in the FB parameter ALARM_SUM change to 1.
