Profinet module located in the Connection Manager and used for communicating Siemens Profinet devices.
When right mouse button clicked in the white area at the left, a menu opens. A new Network is created by clicking Add in this menu.
More than one Network can be created. But each Profinet Network can contain single station. Can not connect to one PLC from two separate network.
Station name and connection configuration settings located in Net. Properties.
Net. Properties dialog box can be accessed by right clicking on station.

Groups:
Tags are created in Groups.
Station can contain multiple groups.
Groups are created for improving communication performance.
By creating Tags in different groups, some Tags can be read at each cycle, some Tags can be read rarely according to specified group cycle parameter.
In this way some PLC values can be read quick, some values can be read slow.
The Tags that read and write to PLC are created in this list. Additionally Tag values can be monitored and set in this list.
Group must be selected to adding or deleting Tags in this list.
If group not selected, Tag values can be monitored or set but Tags can not be added or deleted.
By selecting the group, only the tags, which belongs to that group, are listed.
Groups that created in the station and Tags that balong to group
Tag Creating and Deleting Operations:
Bottom line of the Tag List will be ready for the creating Tag after selecting the group.
Adress Column: Tag's address inside the PLC should be entered this in column. The Tag which will read and write to register will be created by pressing Enter key after typing register address.
Tags that belong to station
Tag List menu opens when right mouse button clicked on Tag List.
On Tag List menu;
Insert, inserts new Tag above the selected Tag.
Cut, cuts selected row or rows.
Copy, copies selected row or rows.
Paste, pastes copies or cut tags.
Delete, deletes selected row or rows.
In Tag list, Rows can be selected by clicking on left side title of the Row. Multiple Rows can be selected by pressing Ctrl key while selecting rows or dragging the mouse.
Selected rows can be deleted by pressing Delete key on the keyboard or selecting Delete command from the right click menu on the related row.
Group Menü:
When right click on Group, Group Menu opens which allows group related operations.
In Group Menu;
Add, creates new group in the station.
Cycle, determines group's read period.
Adding group to the station
All Tags will be listed when Station selected.
When Network selected the Tags listed which belongs to last selected group or station
Name, determines group's name.
Delete, deletes the group.
Monitoring and Setting Tag Values
Tag values that inside the PLC can be monitored and set in this tab. Network connection must be activated to do this.
Activating Network Connection
Created Network connection can be activated by clicking on Connect button that located in the Profinet toolbar or by clicking Connect button on the WinTr toolbar.
Tag values will be read from PLC adresses and shown in the Read Value column in both connection types.
Status Strip:
StatusStrip that locates bottom of the Profinet tab, contains information about Network connection.
First information in this group is Tag Count.
Good is the number of successul communication since Network has been activated.
Bad indicates failed communication count.
Query Byte Count: Most important information of this group. Query is calculated according to entered variable addresses. Then it is sent to PLC. According to calculated query, the byte count that PLC should sent is shown here.
WinTr tries to read all Tags in the group at once. If entered addresses are sequental, all list read at once. In WinTr, maximum 222 byte can be read at once for profinet standart. Calculated query size is shown as the Query Byte Count in the Statusstrip. If you see different count than you estimated, there could be an error.
Adjusting Query Byte Count for Best Performance:
Query Byte Count should be maximum to get high performance. For example we have 13 byte data communication in our Network. Communication performance will be change according addresses to be read .
If 13 byte is reached sequentally, communication performance will be maximum. In this case Query Byte Count will indicate 13.
Activating Network connections
Connect Button that located on WinTr Toolbar activates all Networks.
Connect button on the Profinet tab toolbar activates only selected Network.
To write a PLC, value must be entered to related row's Write Value column then pressed Enter key on the keyboard.
Disconnecting Network
If all networks activated by Connect button on the WinTr toolbar, all network connections will be disconnected if pressed again same button.
If Disconnect button pressed that on the profinet tab's toolbar, network will be disconnected just for a time then it will reactivated immediately.
If Network connection activated by Connect button on the Profinet toolbar, next Disconnect button will deactivate the network.
If same bytes are reached repeatedly, this will cause negative effect on communication performance.
Gap between the bytes that will read has negative effect on communication performance also.
Following 2 illustarations showing lower performance communication.
Tag Name Column: Each newly created Tag will be named with a unique name. This name can be changed by user with another unique name.
Value Type Column: Siemens S7 PLC's data types selected from this column. All types read and transferred to PLC in S7 format. But they are displayed in Windows standart.
Displayed Data Types:
S7-1200 PLC's Input, Output, Marker and Datablock registers can be read and written by WinTr.
Address information specifies data size. For example M 0.0 is one bit size, MD 8 is 4 byte size. Suitable value types determined according to address that entered in this field.
Register addresses can be typed without a space. For example mw8 will be recognized as MW 8.
Tag List:
The list at the right side which contains created tags.
In Net. Properties dialog box,
Station Name, determines station name.
IP Address, determines device IP address to connect.
TCP Port, determines port number to connect..
Poll Interval, determines period of queries that send to PLC. This value ignored when data written to PLC. Value is written to PLC immediately at the time of the command executed.
CPU Slot, determines CPU Slot number.
