DFB Acyclic Mailbox Message: Set Operating Mode - M340
This command allows setting the operating mode of the PROFIBUS Master
(STOP, CLEAR, or OPERATE).
MNETDPV1_MAILVAR_SetOperateMode Variables - M340
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:
ƒ 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.
ƒ 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.
ƒ 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.
