Control of the DALI
bus by means of the PmChar
communication driver with test panel.
This preconfiguration can be activated when creating a new object (e.g. by "New object ..."
in the local object menu or after pressing the Insert
key after selecting the object) and is included in the group: " / Communication / DALI communication protocol"
This preconfiguration can be used with the objects: PmaFolder or PmaRoot.
- The preconfiguration is created including the panel (object of the PmaPanel
type) is functional also a Web panel
The preconfiguration allows to choose two types of connection with the computer:
- via Ethernet
- via the computer's serial port (RS232)
According to the selected type of converter: Communication in DALI networks
The preconfiguration uses the PmChar
communication driver for communication with DALI
bus. The communication interface is based on the method of the created PmaFolder
object named "RunCmd
". Two parameters are passed to this method. First parameter addr
represents the value of device address (or group of devices) in the network. Second parameter cmd
represents the command to be executed.
The designer's "DataToSnd
" method of the PmaComm
object creates complex message format that is then sent by the PmaSequencer
object into the PmaCommMsg
object for processing. Individual phases of the communication are processed into the user logging system by the WriteToLog
method. In the testing panel it is possible to choose a command or query to the DALI
bus and in the right part of the panel it is possible to watch the records of the logging system.
These configurators can be set before the preconfiguration is created:
|The name of created object||Name of the object created in the tree of Pma objects. The maximum name length is 30 characters. This is a system name, so it must contain only alphanumeric and must not contain any diacritics, empty string, spaces and the first character must not be a number.|
|Communication type| Network TCP/IP communication (default)
|Network address||Network address to which the communication will be connected. The address can be entered by both IP address (e.g. 192.168.0.15) or by name (e.g. server11).|
Macro expression can be used for input (it is evaluated after starting the application).
After the preconfiguration is created, the "PmaComm > Setting the parameters of the Ethernet-client > Network address" configurator will be set to this value.
|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.
- The object is not connected to any port after starting the application and the serial port can be selected dynamically by the algorithm (by the PmaComm.OpenPort
- The specified serial port is opened after starting the application. This port must be correctly configured and accessible in the OS Windows
(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.
