Configuration of a PSS9000 counter card CO4uP.

 The Co_CO4uP object is positioned below a SSAB_Rack object in the node configuration.
 The channel objects are already configured with internal ChanCo objects in the card object.

Console

 The card has a terminal port that can be used to view the signal values of the card and to
 trace trouble. To use the terminal port you
 - connect the serial port of the computer to the terminal port of the card.
 - open a consol window on the screen of the computer from the popup menu of the background,
   menu item 'PSS Kort'.
 - view information and help with (Shift) '?'.
 - view the signal values of the card with 'R'.
 For more information about the console program, follow the link below.

Optional description.

Error counter, incremented for every failed read or write operation of the card.
When the error counter reaches ErrorSoftLimit, a message is sent to the console log.
When it reaches ErrorHardLimit, all IO handling is aborted.

Value of the error counter, when a message is sent to the console log.

Value of the error counter, when all IO handling is aborted.

The conversion mask specifies which channel values that is transfered to signal values.
If value of a channel, read from the card, should not be used, the corresponding bit in
the conversion mask is set to 0. The value can then be set from the runtime navigator.

Maximum number of channels.

An extended 32-bit absolute value of the counter is calculated and stored.
The extended value is convenient to use if there is any risk of overflow.
It is fetched into the plc program with the PIX output of the GetPi object.

Number of bits, 16 or 24.
If NoOfBits is 16, bit 12 is set in the configuration word of the counter.

Internal flag.

The number of pulses is multiplied with this factor. 2 or 4.
If MulCount is 2, bit 11 is set in the configuration word of the counter.

The number of pulses is divided with 16. No (0) or 16.
If DivCount is 16, bit 9 is set in the configuration word of the counter.

Copy the value in SyncRawValue to the counter value, when rough sync is detected.
Actually, it is the write register that is copied to the counter value, and the
SyncRawValue is copied to the write register as system startup.
If CopWrRough is true, bit 13 is set in the configuration word of the counter.

Copy the value in SyncRawValue to the counter value, when fine sync is detected.
Actually, it is the write register that is copied to the counter value, and the
SyncRawValue is copied to the write register as system startup.
If CopWrFine is true, bit 14 is set in the configuration word of the counter.

Copy the value in SyncRawValue to the write register and to the counter value.
If LoadWrReg is false, the value in SyncRawValue is copied to the write register, but
not the the counter value.
Bit 15 in the configuration word of the counter is set, if LoadWrReg is true.

Length measurement, triggered by the rough sync signal.
If CopWrRough is true, the counter value will be reset when rough sync is detected,
if false, count will start from the previous value.
Bit 10 in the configuration word of the counter is set.

Speed measurement, pulses per second.
Bit 8 in the configuration word of the counter is set.

If both LengthMeasurement and SpeedMeasurement is set, the counter is only
affected in one direction.

Value copied to the counter value when rough or fine sync is detected.
The value in SyncRawValue is copied to the write register at system startup.
Due to values of CoWrRough an CoWrFine the value in the write register is
copied to the counter value, when a rough or fine sync is detected.

QBUS address of the card.
The value is set with address switches on the card.
NoteThe value in RegAddress is a decimal value

	Card number	Octal address	Decimal address
	1		176300		4193472
	2		176320		4193488
	3		176340		4193504
	4		176360		4193520

The value is filled in when the object is created, calculated
from the current position of the object in the rack. If the
positions is changed the address can be updated with the SetAddress
method in the popup menu.

Settings of the address switch on the board.
The value is filled in when the object is created, calculated
from the current position of the object in the rack. If the
positions is changed the settings can be updated with the SetAddress
method in the popup menu.

The settings are presented with an integer value, and leading zeros
are missing.

Process that handles the card.

1: The card is read by the plc process, and is handled by a specific
   thread in the plc, which is specified in the ThreadObject attribute.
2: The card is read by the rt_io_comm process.
4: The card is handled by an application program.

The PlcThread object of the plc thread that handles the card.
The card read to with the scantime of the thread.

 A URL to the data sheet for the equipment of this object.
 The data sheet can be displayed from the popup menu for this object.

 Array with channel objects.
