7.9.5.11. Optoizolated hourmeters modules.
HM hourmeters modules developed for the MultiCon units. They allows to measure
period of time between START and STOP signals, as well as sum of periods.
These modules are ideal solution to control working time of a machinery, duration of
phenomena or for maintenance purposes. The HM2 and HM4 have 2 and 4 independent
counters respectively. Each counter is equipped with 2 inputs - START/STOP and
programmable, which can be set as asynchronous RESET, HOLD or used as independent
digital input (see
Appendices 8.11. HM2, HM4 – OPTOIZOLATED HOURMETERs
MODULES ).
With the HM module a Time Format functionality of the device is related (see Chapter
7.8.1. Logical Channels - General settings ).
Time format is an advanced method of data presentation in format of time. User can
easily get a desired format, by entering a "formatting string" composed of letters and colons,
for example a string: "w:d:hh:mm" lets user to display data as number of weeks, days, hours
and minutes, separated by colons. This mechanism allows also for dividing the result on two
or three independent channels. The maximum displaying precision is 1/1000 of a second.
Input data must be expressed in seconds.
Hourmeters parameters are:
– Name – each built-in input already has a name given by the device and user cannot
change it, for description of Name parameter see Fig. 7.75 ,
–
Unit
– parameter which displays measurement unit: sec.,
–
Mode
– read only parameter, which displays measured physical quantity:
Time
,
–
Low Limit
– value determining amount of pulses, bellow which in logical channel will
be displayed Lo state,
– High Limit – value determining amount of pulses, bellow which in logical channel will
be displayed Hi state,
–
Start/Stop inp. trig.
- allows to define, when the device should start or stop
counting,
•
high level
– the device is counting time during high value on counting input,
•
low level – the device is counting time during low value on counting input,
•
rising edge – the device starts counting time when it detects rising edge on
input signal. The device stops counting time when it detects another rising edge
on this input.
•
falling edge – the device starts counting time when it detects falling edge on
input signal. The device stops counting time when it detects another falling edge
on this input.
–
Reset now
– button which allows user to manually reset the counter,
– Reset mode – it allows to choose resets for the counter, it has following parameters:
•
disable – no additional resets,
•
from log. channel – an additional reset is logical channel selected from list in
Reset source
parameter, it is activated by high state,
•
external
– an additional reset can be counter’s programmable input, but
Prog. Inp. mode
parameter has to be set as
reset
in order to work it properly,
•
both – both of options shown above are active, but Prog. Inp. mode parameter
has to be set as reset in order to work it properly,
