DFB Acyclic Mailbox Message: Set Operating Mode - Quantum

This command allows setting the operating mode of the PROFIBUS Master

(STOP, CLEAR, or OPERATE).

MNETDPV1_MAILVAR_SetOperatMode Variables - Quantum

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

when you want to send a request to set the PROFIBUS Master/network

operating mode. Possible choices are:

 Operate - Tells the PROFIBUS Master to begin and continue normal cyclic

polling and pass acyclic messages, if requested. The network should be in

Stop mode when you issue this command message.

 Stop - Tells the PROFIBUS Master to interrupt normal cyclic polling. Acyclic

messaging can still be accomplished when the network is stopped. The

network should be in Operate mode when you issue this command.

 Clear - Tells the PROFIBUS Master to attempt to clear diagnostic errors and

re-initialize the PROFIBUS network. The network should be in Stop mode

when you issue this command.
