Inputs
Table 1:
Type and number of inputs
Inputs I7, I8, I11, I12 can also be used as analog inputs. They are
selected in the user program by means of the appropriate syntax
used in the PLC configurator.
When programming the inputs as digital inputs in the user
program, the input voltage of 8 V forms the limit value for the
TRUE/FALSE signals.
Technical data:
Inputs I1, I2, I3, I4 can be used for:
• generating interrupts (inputs I1, I2, I3, I4)
• controlling high-speed counters such as:
– 16 or 32-bit counters, for counting pulses (I1, I2),
up/down counting
– Incremental counters, 32-bit, for processing the signals of an
incremental encoder (I1, I2, I3, I4).
The function is selected in the PLC configuration. However, several
functions cannot be used at the same time.
