"Binary Status Bits Out" - Assignment in Handshake / No-Handshake mode

5.2 No-Handshake Mode

The data channel of the CLV61x Dual Port is operated in No Handshake mode, if the communication

protocol has been configured with CDF600 NO Handshake mode.

The data channel is compatible with the No-Handshake mode of the CDF600 PROFINET, CDF600

PROFIBUS, CMF400 PROFIBUS, CDM425, and PROFINET on Board. The max. telegram length is limited

by the size of the input/output range and is max. 123 bytes. There is no fragmenting / blocking.

In this mode, one input and one output module, Ctrl bits In and Ctrl bits Out must be added in HW

Config for the CLV61x Dual Port. The size can be freely selected. In the input/output modules, 5 bytes are

used for administration. A module may contain from e.g. 32 bytes to 27 bytes of user data.

This mode is only recommended if the length of the received data does not exceed the input range minus 5.

It is also necessary to ensure that the PLC always has enough time to receive the data before the next data

block arrives. Therefore, this mode is only recommended for testing or for individual devices with low

communication load.

To select No-Handshake mode, "CDF600 No-Handshake mode" must be configured and permanently

saved in the ID sensor. The mode is only active after restarting the CLV61x Dual Port.

For the data channel, one input module and one output module must be selected as in CDF600 mode

(Handshake mode). In terms of the layout, the mode is identical to the HS mode except that fragmentation

is not possible on both the receiver and transmission sides.

The binary inputs and outputs are identical to the Handshake mode.

The Ctrl bits can also be used.
