Creates compound object configured as analog pump.
This preconfiguration can be activated when
creating a new Pmg object.
This preconfiguration is included in the
"/ Technology / Pump" group.
After connecting the
variables of this object by the "
PP - Pma object property" data binding to the configured variables of the
PmaData object, the real status of such device is indicated.
The
Status and
Mode variables are used for such purpose. The value of the
Mode variable defines the working mode of the device and is preset as follows:
1 = automated regulation mode
2 = manual regulation mode
3 = manually ON
4 = manually OFF
5 = disabled (for pump)
Any other value causes error signal.
The
Status variable represents the device status and the default (preconfigured) meaning of individual bits of this variable is apparent based on the information present at the beginning of the "
Draw" tab script of the
PmgCanvas object.
All these variables in the
Pmg object are read only.
Displayed symbols and values
Symbols A, M, E, X - indicate the device status (A = AUTO, M = MANUAL, E = ERROR, X = SHUT DOWN) and also differ in background color.
The CurrVal value - is located to the left or to the right of the symbol and represents the real current signalized position (or velocity).
The ReqM value - is located above or below the symbol and represents manually defined desired value (can be written)
The ReqA value - is the last value and represents the value requested by the device from regulation
The
devId parameter serves as device identifier.
The mode change control is executed by means of the
onMenuFill and
onMenuSelect events. It is supposed in this event that the
panel method DeviceCmd exists with
devId and
mode parameters that commands the control system based on user request to change the device mode. There is an example script present in this event that emulates the reaction of the control system.
These configurators can be set before the preconfiguration is created:
| The name of created object | Name (identifier) of the Pmg object. It is used for obtaining the Pmg object by the PmgObject.Items method.
This configurator sets the initial value of the Name property.
The maximum name length is 30 characters.
This is a system name, so it must contain only alphanumeric and must not contain any diacritics (i.e. national dependent characters), empty string, spaces and first character must not be a number. |
