A TTIM(120) timer is based on two execution conditions. These execution
conditions are labeled I and R. I is the timer input; R, the reset input. The timer PV
is clocked while the timer input is ON, maintained when I is OFF, and reset to
zero when R is ON. If both I and R are ON simultaneously, the timer is reset.
TTIM(120) increments in units of 0.1 second from zero. TTIM(120) accuracy is
+0.0/–0.1 second.
