9.6.5 Value comparators
These functions are enabled ONLY with operating mode 11, 13 and 14. The Pr96:95 and
Pr98:97 parameters have the alternative function of value comparators.
With b94.10 = 0, then b94.8 = 1 if Pr96:95 > Pr63:62 (or Pr66:67 if feedback encoder)
With b94.10 = 1, then b94.8 = 1 if Pr96:95 > Pr61:60
With b94.11 = 0, then b94.9 = 1 if Pr98:97 > Pr63:62 (or Pr66:67 if feedback encoder)
With b94.11 = 1, then b94.9 = 1 if Pr98:97 > Pr61:60
This function is run every 6.144 ms.
If the value comparators functions are not used, the Pr95, Pr96, Pr97, Pr98, b94.10 and b94.11
parameters by the PLC program as general purpose registers.
9.6.6 Value capture
At every positive front of digital input 1, the value of Pr63:62 (or Pr66:67) is captured and
stored in Pr68:69 and b70.15 is set to 1 to signal the event. b70.15 is not reset automatically
but must be executed by the pico-PLC or the serial line.
Analogous situation, at every positive front of digital input 0, or from reference mark, the
value of Pr66:67 is captured and stored in Pr58:59 and b70.14 is set to 1 to signal the event.
b70.14 is not reset automatically but must be executed by the pico-PLC or the serial line.
