5.1.9.5.5 Command Output
Standard Command Output
For the output of standard commands (OC) an appropriate digital output module must be
equipped, and the DO signals to be used must be configured.
Common Settings:
·
Monitor pulse duration
The command output time defines how long the actuator is actuated. The output time can
be set for each data point with the parameter output_t.
·
Monitor return information
The return information monitoring is used to limit the command output to the output time
required by the process. The return information monitoring can be activated for each data
point with parameter RS_Mon_t.
·
Procedure for the command transmission according to IEC 60870-5-101/104
The procedure for "direct command" is set by means of the parameter
select_execute_t
The procedure for "select and execute command" is set by means of the parameter
select_execute_t
command must be received following the selection command.
You find the exact information on the command output in the manual SICAM RTUs Common
Functions Peripheral Elements According to IEC 60870-5-101/104, chapter "Pulse Com-
mands", section "Functions Independent on the Hardware of the System Element".
Assignment Return Information to Pulse Command
This function coordinates binary information and pulse commands that are acquired or output
on SICAM TM I/O modules. You find the exact information thereto in the manual SICAM RTUs
Common Functions Peripheral Elements According to IEC 60870-5-101/104, chapter "Return
Information to Pulse Command Assignment".
·
Parameter-settable assignment
The assignment of an information (DI signal) to a pulse command (DO signal) is adjustable
through the 5-digit address of the return information (parameters RS_Image_CASDU1,
RS_Image_CASDU2, RS_Image_IOA1, RS_Image_IOA2, RS_Image_IOA3).
No assignment takes place if the parameters are set to the value
target device utilizes the fixed assignment.
·
Predefined assignment
If the equipped sequence of I/O modules is suitable, an information is assigned automati-
cally to a command. Otherwise no assignment takes place. You find the exact assignment
in the following table.
