| 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" |
|---|---|
| Communication type |
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. |
| 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

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. |
| 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 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. |
| 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. |
