| 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 (i.e. national dependent chars), 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 IPv4 address (e.g. 192.168.0.15) or by computer name (e.g. server11). The IPv4 address 127.0.0.1 is the local address of this computer. 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. |
| TCP/UDP remote port number | Ethernet remote port number for communication.
500 - Ethernet TCP After the preconfiguration is created, the "PmaComm > Setting the parameters of the Ethernet-client > TCP/UDP remote port number" configurator will be set to this value. |
| 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 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 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

14400
19200
38400
57600
115200
128000
256000 |
| Number data bits | Appropriate value for the device, which it is communicated with, must be selected.
This configurator sets the initial value of the ByteSize property. 5
6
7
8 |
| 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. |
| Communication refresh rate [ms] | The period in milliseconds to be used for reading the current data by the PROMOTIC application.
After the preconfiguration is created, the "PmaCommGroup > Parameters > Communication refresh rate [ms]" configurator will be set to this value. |
| Default device address | The address defined here can be used for definitions in the "ItemID" configurator for the variables in this object (i.e. the variables on the "Data" tab or in data extension ExtComm). The address can be entered in ItemID:
- as for example Slave3.D6 - then the value will be read from the PLC device with address 3.
- or not defined, i.e. D6 - and the address is taken from this configurator.
This parameter can be modified and read in the script during runtime by methods: SetSpecParam("SlaveAddr") and GetSpecParam("SlaveAddr"). After the preconfiguration is created, the "PmaCommGroup > Parameters > Special Parameters > Default device address" configurator will be set to this value. |
