Similarly, a freeze control acyclic message causes the addressed slaves to

assume freeze mode. In this operating mode, the states of the inputs are frozen

until the master sends the next freeze acyclic message. Freeze mode is

concluded with the unfreeze acyclic message.

Note 1: It is only possible to send Sync and Freeze control acyclic messages when operating

mode is either "CLEAR" or "OPERATE".

Note 2: Not all slaves support this feature. Refer to the documentation for the actual slave for more

information.

For additional details, see Set Slave Mode Message Structure (page 206).

MNETDPV1_MAILVAR_SetSlaveMode Variables - M340

This variable structure is the one to use with your control and sequencing logic

when you want to send a request to the PROFIBUS Master to send Sync and

Freeze control messages to a slave or group of slaves.
