The
West ProVU4 device is designed for temperature measurement and regulation. The PROMOTIC application communicates with the device by means of the
PmModbusMr communication driver via the
RS485 via the computer's serial port.
The device can be connected to the PC using the
RS485/RS232 converter via the computer's serial port (
RS232). The connection is described in the documentation supplied by the manufacturer of the device.
This preconfiguration can be activated when creating a new object (e.g. by
"New object ..." in the context menu of the object or by pressing the
Insert key after selecting the object).
This preconfiguration is included in the
"/ Communication / Protocols and other communications / Modbus" group.
This preconfiguration can be created in the
PmaFolder,
PmaRoot or
PmaPrototype object.
- The preconfiguration is created including the panel (object of the
PmaPanel type) is functional also as
Web panel.
- The panel serves for communication testing and it is not essential for the communication functionality.
In the
PmaComm object named "
Comm" the communication parameters are set (
Serial port,
Baud rate ...).
The
PmaCommGroup object named "
data" includes a "
Parameters" tab where
Special Parameters are defined (see
PmModbusMr - Driver for communication by the Modbus Master protocol). On the "
Data" tab, the items are imported by data extension of items defined in the
PmaData object (see
ExtComm). Each
Data corresponds to the selected device type by its structure and name stated in the description of the manufacturer protocol.
The
PmaTrendGroup object named "
Trend" contains the setting in the "
Storage type" configurator, that defines saving the trend values into
Database dBase backups. The variables for the
PmaTrendGroup object are defined in the
PmaData object using the
ExtTrend.
The
PmaTrendGroup object is also included in this preconfiguration. The data is connected via
ExtComm from the
PmaData object. The communication diagnostics, the current values and temperature control (via the
PmgSliderBox object) are displayed in the panel (
PmaPanel object). It also contains the trend viewer displaying the current and desired temperature.
These configurators can be set before the preconfiguration is created:
The name of created object | Name of the object created in the Pma object tree.
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.
Default: "Comm_dTRON" |
|
Serial port | Selection of the communication serial port.
The value can be change by the OpenPort method.
The value can be detected by method GetProtParam("SerPort").
After the preconfiguration is created, the "PmaComm > Setting the parameters of the serial link > Serial port" configurator will be set to this value.
Not set - The object is not connected to any port after the application is launched and the serial port can be selected dynamically by the algorithm (by the PmaComm.OpenPort method).
COM1, COM2,..,COM66 - The specified serial port is opened after the application is launched. This port must be correctly configured and accessible in Windows OS (no one can use it).
For serial link each PmaComm object must have defined another communication port. For example, if one PmaComm object communicates through COM1, then next PmaComm object can communicate for example through COM2 (COM3, …) but it mustn't communicate through COM1. |
Baud rate | Selection of the baud rate (bps, bit per second).
This configurator sets the initial value of the BaudRate property.
After the preconfiguration is created, the "PmaComm > Setting the parameters of the serial link > Baud rate" configurator will be set to this value.

Default device address | The device address in the Modbus network. See:Default device address |
|
Communication refresh rate [ms] | The period in milliseconds to be used for reading the current data by the PROMOTIC application.
After the preconfiguration is created, the "PmaCommGroup > Parameters > Communication refresh rate [ms]" configurator will be set to this value. |
