Preconfiguration "PmChar - Communication set with data and panel"

Communication driver configuration PmChar - Driver for communication by user defined ASCII/BIN protocol.

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 / PmChar configurable protocol" group.

This preconfiguration can be created in the PmaFolder, PmaRoot or PmaPrototype object.

The preconfiguration allows to choose two types of connection with the computer:

- via Ethernet

- via the computer's serial port (RS232/RS485..)

The created preconfigured connection is functional usually immediately. Otherwise it is necessary to obtain the connection parameters specified by the device manufacturer and see also PmChar - Driver for communication by user defined ASCII/BIN protocol.

- The panel serves for communication testing and it is not essential for the communication functionality.

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: "CommChar"

Communication type	Network TCP/IP communication (default) Serial communication
Network address	Network address of the remote device (e.g. of the PLC device), to which the communication will be connected. The address can be entered as: - IPv4 full address (e.g. "192.168.0.15") - IPv4 address of this computer (i.e. "127.0.0.1") - IPv4 computer name (e.g. "server11") - IPv4 name of this computer (i.e. "localhost") - IPv6 full address (e.g. "2a02:c38:8136:800a:37a:ab66:6fc9:accd") - IPv6 address of this computer (i.e. "::1") Macro expression can be used for input (it is evaluated after the application is launched). After the preconfiguration is created, the "PmaComm > Setting the parameters of the Ethernet-client > Network address" configurator will be set to this value.
TCP/UDP remote port number	Ethernet remote port number for communication.
Ethernet transfer type	Deatiled Ethernet protocol type specification. TCP (default) - Allows unlimited, security checked data transfers. The data are transferred by separate portions so-called packets. UDP - Only limited data transfers are allowed (often limited only to 500 bytes). The data transfer is very fast.
Close the connection after each transmission	This option sets the following configurators simultaneously: Not connect until first transfer. See: PmaComm > Setting the parameters of the Ethernet-client > Not connect until first transfer Close connection after every transfer. See: PmaComm > Setting the parameters of the Ethernet-client > Close connection after every transfer
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. 110 300 600 1200 2400 4800 9600 14400 19200 38400 57600 115200 128000 256000
Parity	Parity selection. Appropriate value for the device, which it is communicated with, must be selected. This configurator sets the initial value of the Parity property. After the preconfiguration is created, the "PmaComm > Setting the parameters of the serial link > Parity" configurator will be set to this value. NO ODD EVEN
Number of stop bits	Appropriate value for the device to communicate with, must be selected. This configurator sets the initial value of the StopBits property. After the preconfiguration is created, the "PmaComm > Setting the parameters of the serial link > Number of stop bits" configurator will be set to this value. 1 stopbit 1.5 stopbit 2 stopbit

Creates message of the type: Master	After the preconfiguration is created, the "PmaCommMsg > Parameters > Message type" configurator will be set to this value.
Receive data	The data will also be received after sending.
Maximum number of characters in the value
There is HexaString in 'Data-sent'	On the "Data-sent" tab there is always the Data variable of the String type. If checked, then it is presumed that the content of this variable is so-called HexaString that can be used in order to transfer binary values in the String type as follows: Example: if you are to send 4 bytes with binary values of 01 A0 00 B3 (in hexadecimal), then it is necessary to set into the variable of the String type the value of "01A000B3" - i.e. the text of 2*4=8 characters. This way you can easily transfer data containing binary zeroes, that are forbidden in the value of the String type. The Pm.TransformValue(240) method can be used for preparation of the transferred data. If not checked, then it is not possible to send binary data, only text data sending is allowed - the exact content of the of the String type variable is sent.
There is HexaString only in 'Data-received'	The sane as the previous configurator, only for the "Data-received" tab. The Pm.TransformValue(241) method can be used for processing the received data.

Creates message of the type: Slave	After the preconfiguration is created, the "PmaCommMsg > Parameters > Message type" configurator will be set to this value.
Send data	The data will also be sent after receiving.
Maximum number of characters in the value
There is HexaString only in 'Data-sent'	If checked, then it is presumed that there is only a single variable of the String type on the "Data-sent" tab. The content of this variable is so-called HexaString that can be used in order to transfer binary values in the String type as follows: For example if you are to send 4 bytes with binary values of 01 A0 00 B3 (in hexadecimal), then it is necessary to set into the variable of the String type the value of "01A000B3" - i.e. the text of 2*4=8 characters. This way you can easily transfer data containing binary zeroes, that are forbidden in the value of the String type. The Pm.TransformValue(240) method can be used for preparation of the transferred data.
There is HexaString only in 'Data-received'	The sane as the previous configurator, only for the "Data-received" tab. The Pm.TransformValue(241) method can be used for processing the received data.
