5.7.2.2.1 Functions
• Pulse commands
t1
─ Checked output of pulse commands
− 1-pole, 1½-pole, 2-pole
− Cannot be mixed
─ Single, double and regulating step commands
─ Command output (OC)
─ Application functions and procedures according to IEC 60870-5-101/104
− Formal check
− Direct command
− Select and execute command
─ Retry suppression
─ 1-out-of-n check
─ Control location check
─ Command locking
─ Synchronization
─ Revision
─ Command output time
− Settable
− Dependent on the process
─ Return information monitoring
─ Command prolongation
─ Switching sequences
─ Command output for the auto-reclose function
─ If outputs of the module are used for pulse commands, no outputs of the same module
can be used for binary information output
• Binary information output
─ Selectable behavior on communication failure
ta
(deactivation or retention)
─ Deactivation on module failure
ta
─ Spontaneous transmission
t
or
─ Periodical transmission
a
─ If outputs of the module are used for binary information output, no outputs of the same
module can be used for pulse commands
─ Usage of outputs as Watchdog
