5.2.1.6
Command Processing According to IEC 60870-5-101/104
If a command (Activation, ACT) is generated by the controller and output on a peripheral ele-
ment, then the messages for command acknowledgement (ACTCON) and command termina-
tion (ACTTERM) are generated with the corresponding output address of the control.
If the output address of the control is the same as the input address, then both messages are
automatically transmitted again to the control.
If an ACT remains in the control (target = control, no periphery), then an ACTCON, ACTTERM
that is to be possibly simulated can be generated in 1 cycle pass. For this the cause of trans-
mission for the command must be set to
and one ACTTERM respectively will be transmitted.
Example:
LD
0
ST
0_045_001_001_001.COT
LD
1
ST
0_045_001_001_001.S
If this function is not used, the ACTCON and ACTTERM can also be generated individually (for
this at least 2 cycle passes are required).
Note
The corresponding typ identification can be generated by means of Verwendung of utilization of the com-
mand "with/without time" (for instance TI 45/TI 58).
Single Command and Double Command
Single commands (TI 45) can be generated by the IL only with the states
0
(OFF) only with COT = 7, 10 (CON, TERM) and S = 1
1
(ON)
Double commands (TI 46) can be generated by the IL only with the states
01
(OFF)
10
(ON)
Other states will not generate a command output.
You find the details for the processing of commands in the manual SICAM RTUs Common
Functions System and Basic System Elements, chapter "Automation", section "Treatment for
Commands to the Open-/Closed-Loop Control Function according to IEC 60870-5-101/104".
5.2.1.7
Generation of Integrated Totals
There are two possibilities of integrated total generation in the control:
·
Spontaneous transmission with change
Automatically if the input address is unequal to the output address of the controller.
·
Behavior according to parameter setting of the digital inputs (remote control)
Automatically if the input address is equal to the output address of the controller.
