Additional Information CLV61x Dual Port (PROFINET IO)

5.1.7 Example 3, transmission of a single block telegram (HS mode)

Input: 16 bytes, output: 16 bytes, data telegram with 4 bytes "sRI0" is sent.

The CLV61x Dual Port responds with "sRA ...".

The command can be used to query the software version of the sensor / SDD file or to generally check the

communication channel. This command can be used for all SOPAS ET based Cola-A sensors (CLV6xx, LECTOR62x,

RFH6xx, RFU6xx, etc.) irrespective of the configuration.

Time: 1/2 3/4 5 6/7 8

Remarks:

Time 1: First data telegram "sRI0" (SDD version) was sent by setting TransmitCount = 1 on the output side. If the

CLV61x Dual Port has sent the data, it confirms it by copying TransmitCount to TransmitCountBack on the

input side.

Time 2: The CLV61x Dual Port responds with "RA 0 6 CLV62x 5 V5.11" (22 bytes). The first 11 bytes ("sRA 0 6 CLV")

are reported to the PLC with ReceiveCount = 1 and ReceiveLength 22 bytes (total length).

The PLC has detected the data and because it has noted that 22 bytes does not fit in the input range,

it knows that another block follows. It confirms the first block by copying ReceiveCount to ReceiveCountBack.

Time 3: The CLV61x Dual Port immediately sends the next (last) block "62x 5 V5.11" (11 bytes) to the PLC with

ReceiveCount = 2 and ReceiveLength = 11.
