Preconfiguration "PmModbusMr - West 6100+ temperature sensor and regulator (Modbus RTU) - Communication set with data and panel"

Communication driver configuration PmModbusMr - Driver for communication by the Modbus Master protocol.
 
The West 6100+ device is designed for temperature measurement and regulation. The PROMOTIC application communicates with the device by means of the PmModbusMr communication driver.

See also Communication with meters and regulators by the West Instruments company.

 
The device can be connected to the PC using the terminals no 11 and 12 (RS485) via the RS485/RS232 converter via the computer's serial port (RS232). The connection is described in the manual supplied by the manufacturer of the device.
 
This preconfiguration can be activated when creating a new object (e.g. by "New object ..." in the local object menu or after pressing the Insert key after selecting the object) and is included in the group: " / Communication / Modbus communication protocol".

This preconfiguration can be created in the object: PmaFolder or PmaRoot.

 
- The preconfiguration creates an object of the PmaFolder type containing PmaComm object with PmaCommGroup subobject and following objects: PmaPanel, PmaData, PmaTrendGroup, PmaAlarmGroup.
- The preconfiguration is created including the panel (object of the PmaPanel type) is functional also a Web panel.
- The panel is used for communication testing and it is not essential for the functionality.
 
In the PmaComm object named "Comm" the communication parameters are set (Serial port, Baud rate ...).

The PmaCommGroup object named "data" includes a "Parameters" tab where Special Parameters are defined (see PmModbusMr - Driver for communication by the Modbus Master protocol). On the "Data" tab, the items are imported by data extension of items defined in the PmaData object (see ExtComm). Each Data corresponds to the selected device type by its structure and name stated in the description of the manufacturer protocol.

 
The PmaTrendGroup object named "Trend" contains the setting in the "Storage type" configurator, that defines saving the trend values into Database dBase backups. The variables for the PmaTrendGroup object are defined in the PmaData object using the ExtTrend.
 
The PmaPanel object contains trend viewer PmgTrendViewer and PmgWTable. There are also PmgButton objects for entering values and for controlling the viewer. The PmgRasterImage objects indicate the current status by colors and PmgString objects contain description texts or values displaying the current status of the measurement.
These configurators can be set before the preconfiguration is created:
The name of created objectName 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: "CommWest6100"

PermissionsOn this tab permissions of the object are defined. See the "Permission" tab of the PmaObject object.
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 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 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.

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.

Autosave period [s]The period in seconds. Each time this period passes the Run method is called internally, then the onAddRecord event is triggered and then saves all current values on the "Data" tab.

After the preconfiguration is created, the "PmaTrendGroup > Trend > Autosave period [s]" configurator will be set to this value.
