Additionally, it is possible to configure polarization of each digital
input. It’s done at parameter
DIPol
.
Value of this parameter reflects binary state of 8 bit number, in which bits are responsible for
polarization of appropriate input (bit0
–
DI1, bit1
–
DI2, etc.). If bit has value of 1, active state of that
input is input shorted.
Outputs
PTZ-
BOX 5.0 is equipped with four controlling outputs of „open collector” type, which allow
cooperation with external systems of automation and signaling. Outputs are made in intrinsically safe
version, so it’s required to use Ex barriers when connecting external non
-intrinsically safe devices.
Available work modes of outputs:
•
output switched off (open) (
DOxMode
= 0)
•
counter output (volume or energy), active
–
short (
DOxMode
= 1)
•
status output (active
–
short) (
DOxMode
= 2)
•
time synchronized output (active
–
short) (
DOxMode
= 3)
•
output switched on (short) (
DOxMode
= 4)
•
counter output (volume or energy), active
–
open (
DOxMode
= 5)
•
status output (active
–
open) (
DOxMode
= 6)
•
time synchronized output (active
–
open) (
DOxMode
= 7)
•
HF output (only DO1) (
DO1Mode
= 8)
•
events output (active
–
short) (
DOxMode
= 9)
•
events output (active
–
open) (
DOxMode
= 10)
•
fixed frequency (test mode) (
DOxMode
= 15)
It is possible to configure properties of output pulses for each output, with parameters
DOxPulseLen
(pulse length
–
high state) and
DOxPulsePer
(period duration), “x” –
means output number, values
1
÷
4.
Description of available modes is in following paragraphs.
6.2.1
Counter output
This mode allows to output pulses proportional to increments of selected counter. To use this mode
(
DOxMode
= 1 or 5), index of selected counter has to be programmed into
DOxIdx
parameter. Pulse
factor (
DOxFactor
–
value increase of selected counter per one output pulse) is by default set to 1 if
selected counter is from volume group and set to 10 if selected counter is from energy group.
6.2.2
Status/events output
These modes are allowing to control outputs with selected events. There are two types of event-
controlled modes:
•
status output (modes 2 and 6): when configured (index of selected event is programmed into
parameter
DOxEvt
), output is controlled as long as selected event is active,
•
event output (modes 9 and 10): when configured (index of selected event is programmed
into parameter
DOxEvt
), output is controlled as long as selected event is active or
it’s turned
off when configured time
DOEvtTm
passes, whichever occurs first.
6.2.3
Frequency output
DO1 can be set to frequency mode (
DO1Mode
= 8), where it can output signal with frequency
controlled by selected parameter from the list:

Qm
