Preconfiguration "PmModbusSl - Minimal set of the PmaComm object"

Communication driver configuration PmModbusSl - Driver for communication by the Modbus Slave protocol.

This preconfiguration can be activated when creating a new object (e.g. by "New object ..." in the local object menu or by pressing the Insert key after selecting the object) and is included in the group: "/ Communication / Protocols and other communications / Modbus".
This preconfiguration can be created in the object: PmaFolder or PmaRoot.

Preconfiguration for serial link.
The created preconfigured connection is functional usually immediately. Otherwise it is necessary to obtain the connection parameters specified by the device manufacturer or see also PmModbusSl - Driver for communication by the Modbus Slave protocol..
These configurators can be set before the preconfiguration is created:
The name of created objectName 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"
Serial portSelection 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 rateSelection 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.

ParityParity 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.
NO
ODD
EVEN
Number of stop bitsAppropriate 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
