Technology CPU: Configuring PROFIBUS DP (DRIVE)
1. After selecting the Technology CPU, the "Properties - PROFIBUS interface DP(DRIVE)
(R0/S3.1)" dialog box will be displayed. Click the "New" button to create a new
PROFIBUS network there.
2. In the "Network settings" tab of the "PROFIBUS Properties" dialog, set the following
properties:
– Highest PROFIBUS address: 2
The setting of the highest PROFIBUS address should correspond to the highest
address of an active PROFIBUS node. This setting reduces the PROFIBUS time to
search for a new active PROFIBUS node.
– Transmission rate: 12 Mbps
This transmission rate permits the largest possible data throughput on the PROFIBUS.
Pay attention, however, to the maximum transmission rate of the CP in the
programming device. If the value is set too large, access to the CPU will no
longer be possible.
– Profile: "User-defined"
The "user-defined" setting is required, when a message frame extension with
BICO wiring is required in addition to the standard message frames.
