Example: If you are using input I1 for a high-speed counter (16-
bit), I2 can be used for another high-speed counter (16-bit) but not
for generating an interrupt. Inputs I3 and I4 likewise cannot be
used for generating an interrupt.
Connection description
a figure 22 on page 23.
Function and cursor buttons as inputs
The front plate of the device is provided with the function buttons
DEL, ALT, ESC, OK which are arranged around the rocker switch.
The rocker switch is divided into 4 sections with the cursor button
designations P1 to P4. The function and cursor buttons are
represented in the PLC configuration as inputs. These inputs are
scanned in the program according to general syntax rules. Only
one button can be actuated at a time, otherwise uncontrolled
states may occur when these buttons are scanned.
The GetDisplayInfo function block from the EC_Visu2.lib library
enables you to control the scanning of the buttons according to
the active menu on the controller,
a section
“EC_Visu.lib/EC_Visu2.lib library”, page 62.
Diagnostics inputs
The inputs I13, I14, I15, I16 provide you with additional
information:
The inputs can be scanned in the program with symbolic operands.
Inputs for high-speed counters
You can choose between several different functions:
•1 x 32-bit counter, for counting pulses (up/down)
•2 x 16-bit counters, for counting pulses (up/down); the count
direction (up/down) can be set via the DIRECTION operand in
the program.
•1 x incremental value counter, 32-bit, for processing the
signals of an incremental encoder; the count direction is set by
the edge sequence of the encoder.
You can select the counter type in the PLC configuration.
The function of the high-speed counter requires the setting of
inputs and the scanning of outputs in a POU, e.g. PLC_PRG.
This POU must not be called by an interrupt generated by a
counter.
For further information see section “High-speed counters
(Counter)”, page 45.
