5.1.4 Example 1, receipt of a single block telegram (HS mode):

Input: 16 bytes, output: 16 bytes, data telegram with up to 11 bytes  single block

This can be done by triggering the CLV61x Dual Port, e.g. via the trigger git in the Ctrl bits.

Only data can then be received by the PLC.

Time:

1 2 3 4

Remarks:

Time 1: The initial data block "CLV6xx-Data" (11 bytes) has been received and the PLC shows ReceiveCount = 1.

Time 2: The PLC has detected the data and confirms it by copying from ReceiveCount to

ReceiveCountBack. The CLV61x Dual Port is now ready for the next data block.

Time 3: The next data block "123456789" (9 bytes) has been received by the CLV61x Dual Port and the PLC

shows ReceiveCount = 2

Time 4: The PLC has detected the data and confirms it by copying from ReceiveCount to

ReceiveCountBack. The CLV61x Dual Port is now ready for the next data block.
