Additional Information CLV61x Dual Port (PROFINET IO)

5.2.3 Example 5, receive telegram (NH mode):

Input: 16 bytes, output: 16 bytes, data telegram with up to 11 bytes are possible. No Handshake is required.

This can occur, for example, by triggering the CLV61x Dual Port

via the fieldbus trigger bit, so that the PLC only has to

complete data receipt.

Time: 1 2 3

Remarks:

Time 1: The first data block "12345678" (8 bytes) has been received and the PLC shows ReceiveCount = 1

Time 2: The second data block "SICK" (4 bytes) has been received and the PLC shows ReceiveCount = 2.

Time 3: The third data block "NoRead" (6 bytes) has been received and the PLC shows ReceiveCount = 3
