Additional Information CLV61x Dual Port (PROFINET IO)

5.1.8 Example 4, transmission of a blocked telegram (HS mode):

Input: 16 bytes, output: 16 bytes, data telegram software trigger "sMN mTCgateon“ with 13 bytes.

Because the telegram is too long, 2 blocks are required.

This command can be used for all ID sensors (CLV6xx, Lector6xx, RFH6xx, RFU6xx, etc.) for triggering. The trigger

source must be configured to (SOPAS) command.

A successful reading with output is immediately shown. If desired, the command "sMN mTCgateoff" (14 bytes) can

also be used to terminate the trigger. This is not shown here.

Time: 1 2/3 4 5 6 7

Remarks:

Time 1: The first data block of 11 bytes has been sent by setting TransmitCount = 1

with TransmitLength = 13.

If the CLV61x Dual Port has received the first data block, it confirms it by copying TransmitCount to

TransmitCountBack on the input side.

Time 2: The second data block of the last 2 bytes has been sent by incrementing from

TransmitCount = 2 with TransmitLength = 2.

If the CLV61x Dual Port has received the second data block, it confirms it by copying TransmitCount to

TransmitCountBack on the input side.

Time 3: The CLV61x Dual Port sends the echo of the trigger command "sMN mTCgateon" to the PLC with

ReceiveCount = 1 and ReceiveLength 15 bytes.

Time 4: The PLC confirms receipt of the first 11 bytes with ReceiveCountBack = 1.

The CLV61x Dual Port then sends the remaining 2 bytes to the PLC with ReceiveCount = 2 and RecLength = 2.

Time 5: The PLC confirms receipt of the data with ReceiveCountBack = 2

Time 6: On receiving "Output immediately", the CLV61x Dual Port sends the result immediately, e.g., upon detection of

the bar code.

10 bytes ("1234567890") are reported to the PLC with ReceiveCount = 3 and ReceiveLength 10 bytes.
