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 the PmModbusMr - Driver for communication by the Modbus Master protocol 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 by pressing the Insert key after selecting the object) and is included in the group: " / Communication / Modbus communication protocol".

This preconfiguration can be used with the objects: PmFolder or PmRoot.

- Preconfiguration creates an object of type PmFolder containing PmComm object with PmCommData subobject and following objects: PmPanel, PmData, PmTrend, PmAlarmEvent.
- The preconfiguration is created including the panel (PmPanel object) functionality as a Web panel.
- The panel is used for communication testing and it is not essential for the functionality.
In the PmComm object named Comm the communication parameters are set (Serial port, Baud rate ...).

The PmCommData object named data includes a Parameters page where Special Parameters are defined (see PmModbusMr - Driver for communication by the Modbus Master protocol). On the Data page, the items are imported by the data extensions of the items defined in the PmData object (see ExtComm). Each Data corresponds to the selected device type by its structure and name according to the description provided bythe manufacturer.

The PmTrend object named Trend contains the setting in the configurator Storage type, that defines saving the trend values into Database dBase backups. The data items for the PmTrend object are defined in the PmData object using the ExtTrend.
The PmPanel object contains ActiveX trend viewer TrendsView and PmTable. There are also PmiButton graphic items for entering values and for controlling the viewer. The items PmiRasterImage indicate the current status by colors and items PmiText 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 application object tree. This is a system name and must not contain diacritics, empty string, spaces and the first character must not be a number.

Default: "CommWest6100"

PermissionsOn this page permissions of the object are defined. See Description of the page Permissions.
Serial portSelection of the communication serial port.

Value can be change by OpenPort method. The value can be detected by method GetProtParam(""SerPort"").

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 rateSelection 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]
Autosave period [s]Autosave period in seconds. Each time this period passes the Run method is called internally, which first generates the onAddRecord event and then saves all current values from the Data page.

After this preconfiguration is created, the configurator is se to: PmTrend > Trend > Autosave period [s].
