The created preconfigured connection is usually functional immediately. In other cases, it is necessary to obtain the connection parameters specified by the device manufacturer or in the documentation: PmElgas2 - Driver for communication with Elgas devices.
|The name of created object||Name of the object created in the application object tree. This is a system name and must not contain empty string, diacritics, spaces and the first character must not be a number.|
|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 while the application is launching).After this preconfiguration is created, the configurator is se to: PmComm > Settings of the Ethernet parameters > Network address
|TCP/UDP port number||Ethernet port number for communication. For communication with the PLC this number is usually hardware predefined and the PROMOTIC application must use the same value (see the note below).|
|Serial port||Selection of the communication serial port.|
After this preconfiguration is created, the configurator is se to: PmComm > Settings of the serial link parameters > Serial port.
Not set - The object is not connected to any port at the start of the application and the serial port can be selected dynamically by the algorithm (by the PmComm.OpenPort method).
Modem - The object is meant for the data transfer over the dialed phone line (over the PmModem object). The serial port is assigned by the PmModem.SetPmComm method or by the PmComm object configurator of the PmModem object.
COM1, COM2,..,COM66 - The specified serial port is opened at the start of the application. This port must be correctly configured and accessible in the OS Windows (no one can use it).
For serial link each PmComm object must have defined another communication port. For example, when one PmComm object communicates through COM1, then next PmComm 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 property BaudRate.
After this preconfiguration is created, the configurator is se to: PmComm > Settings of the serial link parameters > Baud rate
|Communication refresh rate [ms]||The time period in milliseconds to be used for reading the data by the PROMOTIC application. After this preconfiguration is created, the configurator is se to: PmCommData > Parameters > Communication refresh rate [ms]|
