Changes that you make in this box will be applied to all of the selected terminals in the terminal grid control.

In the Select Terminal Information dialog box, make any modifications to the selected terminals.

If you want to modify multiple terminals at the same time, select the terminals, click the right mouse button, and select Edit Terminal from the menu.

If you want to modify the terminals one at a time, either make your changes on the PLC Database File Editor dialog box (using the drop-down list boxes or text boxes) or select a single terminal (making sure to select the entire row if you want to change more than one field), click the right mouse button, and select Edit Terminal from the menu.

You can also select multiple terminals if you want the terminals to carry the same information.

You can select multiple fields to edit at the same time by dragging your mouse across contiguous fields or by holding down the Control key while selecting non-contiguous fields. Inside the terminal grid control there are drop-down list boxes, text boxes, and context menus that you can use to modify the terminal information. Select the module to modify from the tree structure.It is also possible to perform adjustment and measurement of the cycle time. In addition, TwinCAT offers extensive debug functionalities (breakpoint, single step, monitoring, …), which facilitate commissioning. The PLC programs can be written in five different programming languages (IL, FBD, LD, SFC, ST). The programming system TwinCAT for the BC5250 operates, independently of the manufacturer, in accordance with IEC 61131-3. Controller for distributed signal processing Similarly, pre-processed data can be exchanged between the Bus Terminal Controller and the higher-level controller via the fieldbus. Each Bus Terminal can be configured in such a way that it exchanges data directly through the fieldbus with the higher-level automation device. The inputs and outputs of the connected Bus Terminals are assigned in the default setting of the PLC.

If the software PLC TwinCAT is in use, the PLC program can also be loaded via the fieldbus. The configuration/programming interface on the BC5250 is used to load the PLC program.

The Bus Terminal Controller is programmed using the TwinCAT 2 programming system according to IEC 61131-3. The DeviceNet Controller offers automatic baud rate detection up to 500 kbaud and two address selection switches for address assignment. The “Compact” BC5250 Bus Terminal Controller for DeviceNet extends the Beckhoff small controller series by a cost-optimized version in a compact housing. The Bus Terminal Controllers are Bus Couplers with integrated PLC functionality.
