 +====== THE COUNTER3 DEVICE ======
  
 +
 +====== - Introduction ======
 +The COUNTER3 device is used to acquire information from a two-way counter. Its main characteristics:
 +
 +  * conversion of pulses to selected unit measures
 +  * position updating with recovery of unit measure fractions
 +  * position capturing on activation of an interrupt digital input 
 +  * comparison between measured position and an activation threshold of digital outputs.
 +
 +
 +===== - Declaring the device=====
 +
 +To use the device it has to be declared in the INTDEVICE section of the configuration unit. 
 +
 +<code QCL>
 +INTDEVICE
 +<device name> COUNTER3 <TCamp> <ICont> <IdxA> <Out1> <Out2>
 +</code>

 +===== - Execution Description =====
 +A block chart of the device:\\
 +{{:software:devices:counter3:counter3_001.png?nolink&600|}}
 +
 +=== - Factors ===
 +The "Factors" block calculates the conversion factors for position and speed.
 +The "position factor" (PF) is a position conversion coefficient expressed in the unit measure of the of the transducer in the position unit measure (Um), and vice versa. Usually the position unit measure is, for example, metres or millimetres or centimetres, while the transducer unit measure, as an encoder, is always pulses. The parameters used to calculate the position factor are //pulse// and //measure// and it is calculated as a ratio between the two.
 +
 +=== - Acquisition of the actual position on an interrupt digital input ===
 +
 +The //INTENBL// and //INTDSBL// commands enable (//st_intenbl//=1) and disable (//st_intenbl//=0) the interrupt line connected to the zero pulse of the transducer or another sensor. The value of the //capture// parameter defines which pulse front the instant count is frozen and the count captured is introduced in the //delta// parameter. The //st_capture// status signals that the capture is made.
 +
 +=== - Comparators ===
 +The device also provides two comparators that can be used to compare the actual value of the //posit// parameter with two values (//setpoint1// and //setpoint2//) set by the programming. As a result the comparators act on two digital outputs, activating or disactivating them when the set thresholds are met according to various conditions.
 +There are two outputs available (as seen in the the device declaration and block chart) and there is a good level of  personalisation: each comparator can select which output to command and based on which conditions.
 +The //mode1// parameters (controlling comparator 1) selects the activation or disattivazione policy of the corresponding output according to given rules.
 +
 +{{:software:devices:counter3:counter3.png?nolink&600|}}
 +
 +The figure shows examples of the different execution modes:
 +  * mode 0: the output stays in its status
 +  * mode 1: the output is activated when the position in pulse fronts is greater than the setpoint;
 +  * mode 2: the output is disactivated when the position in pulse fronts is greater than the setpoint;
 +  * mode 3: the output is activated when the position in pulse fronts is less than the setpoint;
 +  * mode 4: the output is disactivated when the position in pulse fronts is less than the setpoint;
 +  * mode 5: the output is activated when the position in pulse fronts is greater than the setpoint and is disactivated when the position in pulse fronts is less than the setpoint;
 +  * mode 6: the output is disactivated when the position in pulse fronts is greater than the setpoint and is activated when the position in pulse fronts is less than the setpoint.
 +  * 
 +=== - Delta Actual position ===
 +The device always gives the absolute position of the axis. The count change can also be performed by directly writing the new value of the 
 +//posit// parameter.\\
 +If 100 unit measures are subtracted from the count:\\
 +<code QCL >
 +  Count.posit = Count.posit - 100
 +</code>
 +An error is introduced because it sets the position “//posit// = -100”, when the axis may have an intermediary position between one unit measure and the next (e.g. 100.3). This fraction (0.3) is lost and if repeated can cause a build up of a significant error.\\
 +For this reason there is the DELCNT command that can change the posit by a value set by the //delta// parameter.\\
 +For instance, if //pulse// and //measure// are configured to express the position in tenths of a degree and //posit// expresses the angular position. For this to always fall between zero and 360 degrees, the following code must be added:
 +<code QCL >
 +  IF Count.posit GE 3600
 +    Count.delcnt = -3600
 +    Count.DELCNT
 +  ENDIF  
 +</code>
 +
 +For the command execution conditions see its specific description.
 +Execution of the DELCNT command is ensured even if a unit measure cannot be expressed as a finite number of pulse fronts. For instance with parameters measure = 1000 and pulse = 1024, the value 3600 of the previous example corresponds to 3686.4 pulses. A complex internal algorhythm allows the device to consider the decimal part of this value and by internal accumulators, it becomes part of the information used to change the posit value.\\
 +** Example: **\\
 +If //pulse// = 10, //measure// = 1,  the axis position reading is 2 and it is found at point A. 
 +
 +To add two unit measures to the //posit// position.
 +The instructions :
 +<code QCL>
 +  Count.posit = Count.posit + 2
 +</code>
 +take the axis to the new position B.
 +The instructions:
 +<code QCL>
 +  Count.delta = 2
 +  Count.DELCNT Asse
 +</code>
 +take the axis to position C.\\
 +
 +If //posit// is modified directly without using the //DELCNT// command (as in the first example) an error is introduced.
 +
 +{{:software:devices:counter3:counter3_02.png?nolink450|}}
 +
 +^:info:^To send a sequence of //DELCNT// commands, it is best to calculate the size of the addition and only send the command once. If this is not possible great care must be taken to avoid sending a sequence of commands not separated by a read instruction on the device parameter.\\ Example:\\ <code QCL>Count.delta = 3
 +Count.DELCNT
 +WAIT Count.delta
 +Count.delta = 40
 +Count.DELCNT
 +</code>^

 +===== - Errors management =====
 +
 +The presence of an error in device is reported in the state //st_error//.\\
 +When //st_error// is equal to 1, we find in the variable //errcode// the type of error intervened (see table) and in the variable //errvalue// an indication of the cause of the error.\\
 +If the device is in error, to resume production you need to erase the state through the command //RSERR//
 +
 +===== - Warnings management =====
 +
 +The presence of a warning in device is reported in the state //st_warning//.\\
 +When //st_warning// is equal to 1, we find in the variable //wrncode// the type of warning intervened (see table) and in the variable //wrnvalue// an indication of the cause of the warning.

 +^Code^Priority^Description^
