5.7 I/O Master Module and I/O Modules
The virtual I/O Master Module is jointly with the integrated and optional external I/O Modules
responsible for the process data input and output. The processing is performed partially by
• firmware (example: smoothing of measured values, time tagging)
• hardware (example: filter, ADC, 1-out-of-n check, DAC)
The peripheral functions are specific for each I/O Module.
Note
The functions and the belonging mode of action are described in detail in the manual SICAM RTUs Com-
mon Functions Peripheral Elements according to IEC 60870 5 101/104.
In the following listing, footnotes are used to specify the effect of the functions in detail.
t
Telecontrol
the function affects process information which is spontaneously transmitted
t1
Telecontrol
the function delivers (acquisition) spontaneously transmitted process information or is con-
trolled by such information (output); partly, periodically transmitted information is also cre-
ated/required
a
Automation
the function affects process information which is periodically transmitted
c
Calculation
the function affects process information which is used as input for the calculation of calculated
(derived) values
