Binary Information Acquisition - Siemens CP-8000 User Manual

9.1.11.5.1 Binary Information Acquisition

For the acquisition of single-point or double-point information items, an appropriate digital in-
put module must be equipped, and the DI signals to be used must be configured.
Power Monitoring
You can activate the power monitoring for digital inputs jeweils with the parameter
SVM_monitoring. The monitoring takes place by groups:
Group 0: IOM x – IN D00...IN D07
Group 1: IOM 1 – IN D10...IN D13 (for DI-810x)
IOM x – IN D10...IN D17 (for DI-610x, DI-811x)
For the power monitoring, the last input of a group (IN D07 and IN D13 resp. IN D17) must be
wired with the protected sensor voltage. Thereby the number of process information items is
reduced to 7 resp. 3 inputs for each group.
By means of a further parameter, the power monitoring can be parameterized this way, that
not one input for each group is responsible for the monitoring, but the last input of an
I/O Module for the entire automation unit. Thereby the desired I/O Module is selected.
Note
With a mixture of 1 ms and 10 ms input modules, the power monitoring should be set on an input module
with 1 ms accuracy.
You find further information in the manual SICAM RTUs Common Functions Peripheral Ele-
ments According to IEC 60870-5-101/104, chapters "Single-Point Information" and "Double-
Point Information", respectively in the section "Sensor Voltage Monitoring (Power Monitoring)".
9.1.11.5.2 Counting Pulse Acquisition
Standard Counting Pulse Acquisition
For the acquisition of counting pulses, an appropriate digital input module must be equipped,
and the DI signals to be used must be configured.
Power Monitoring
You can activate the power monitoring for digital inputs jeweils with the parameter
SVM_monitoring. The monitoring takes place by groups:
Group 0: IOM x – IN D00...IN D07
Group 1: IOM 1 – IN D10...IN D13 (for DI-810x)
IOM x – IN D10...IN D17 (for DI-610x, DI-811x)
For the power monitoring, the last input of a group (IN D07 and IN D13 resp. IN D17) must be
wired with the protected sensor voltage. Thereby the number of process information items is
