Page 15: Profinet Network Arrangement
Chapter 3. Application System Architecture PROFINET Network Arrangement A ring topology using MRP is the preferred arrangement. With this topology, a system may use a combination of PROFINET System Redundancy (PNSR) devices and non-PNSR devices (specifically Genius Communication Gateway modules). Also, systems may incorporate managed network switches that support MRP. -

Chapter 4. Toolchest Components Dual Bus Mapper Each dual bus will require a separate instance of the DBUS function block. In this case the block refers to the first dual bus. The name DB00 relates to the first bus. Figure 11: Edit Block for Mapping Each Dual Bus Note the bus variable on the left side of the function block. -
Page 24: Adding A Dual Bus Configuration Block
Chapter 4. Toolchest Components Adding a Dual Bus Configuration Block Each dual bus requires the addition of a unique configuration block. To add a block, follow the steps below: In the Navigator pane, right-click on INIT_GBnn. (This block is the general template, since all of its entries have been initialized to zeroes). -

Chapter 4. Toolchest Components Click and zoom into INIT_GBnn, so that the “soft” configuration parameters associated with the dual bus may be updated. (Note: in this case nn represents any of the dual busses that have been included in the project). The various parameters are described in the following paragraphs. -

Toolchest Components NOTE: Devices that contain outputs must be configured so that the dual mapping routine can post loss-of-device or addition-of-device messages. Also, the device status (i.e., the presence on either Bus A or Bus B) is shared between the Primary and Secondary PLCs for the purpose of Automatic Role Switching (if enabled).
