| The name of created object | Name of the object created in the Pma objects 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 the 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. |
| 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

| Response receipt timeout | The time (in milliseconds) the driver is waiting for the response on sending the message.
If no response comes during this time, then the transmission of the message is terminated (the onEndOfTransfer event is triggered with error 24 or 66). |
| Filter ECHO chars | Specifies whether the received data have to be removed (filtered) because it goes about repeating characters transmitted from the message.
Note: Received filtered ECHO characters are recorded together with other characters in the "/COMM/Monitor" item of the INFO system. No (default)
Yes - Filter. As many first received characters are removed as many characters were transmitted last. For example, some optical heads. |
