This preconfiguration can be created in the object: PmaFolder or PmaRoot.
The created preconfigured connection is functional usually immediately. Otherwise it is necessary to obtain the connection parameters specified by the device manufacturer or in the documentation: PmIEC8705 - Driver for communication by protocol of the IEC 60870-5 standard.
| 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. Default: "Comm" |
|---|---|
| Communication type | Serial communication |
| 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. Not set - 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 method). COM1, COM2,..,COM66 - 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. |
| 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 |
| ASDU common address size | The number of bytes (octets) for the ASDU Common address data: 1/2 bytes (PmaComm > Parameters > Protocol parameters) 1 2 (default) |
| ASDU information object address size | The number of bytes (octets) for data object adress: 1/2/3 bytes (PmaComm > Parameters > Protocol parameters) 1 2 3 (default) |
| Size of "cause of transmission" value | The number of bytes (octets) for the "cause of transmission": 1/2 bytes (PmaComm > Parameters > Protocol parameters) 1 2 (default) |
| Link address of this station | The link address of the computer, running the PROMOTIC application (PmaComm > Parameters > Protocol parameters) |
| Link address of the second station | The link address of the station, the PROMOTIC application comunicates with: For "Balanced mode": Communication only with one station. The LinkAddr variable on the "Data-sent" tab of every Master message is not taken into consideration. For "Unbalanced mode": This configurator is not shown. The address is entered in the LinkAddr variable on the "Data-sent" tab of every Master message. (PmaComm > Parameters > Protocol parameters) |
