Pulse encoder without direction signal:
The count signal is connected to the A connection.
● Pulse encoder with direction signal:
The count signal is connected to the A connection. The direction signal is connected to
the B connection.
● Pulse encoder with up/down count signal:
The up count signal is connected to the A connection. The down count signal is
connected to the B connection.
You can connect the following encoders or sensors to the A, B and N inputs:
● Sourcing output:
The encoder or sensor switches the A, B and N inputs to 24 V DC.The digital inputs are logically assigned to the high-speed counters (HSC). For information
on the possible assignment of the on-board I/O inputs to the high-speed counters, refer to
the table Interconnection overview of the inputs (Page 108). Up to two digital inputs are
available for each high-speed counter (HSC DI0 and HSC DI1). You can use the digital
inputs for the gate control (Gate), synchronization (Sync) and Capture functions.
Alternatively, you can use one or more digital inputs as standard digital inputs without the
functions mentioned and read the signal state of the respective digital input using the
feedback interface.
Digital inputs that you do not use for high-speed counting are available for use as standard
DIs.
Input addresses of the high-speed counters
You set the digital input addresses used by the high-speed counters (HSC) and the
assignment of A/B/N, DI0, DI1 and DQ1 signals in STEP 7 (TIA Portal). You can enable and
configure each HSC when you configure the compact CPU.
The compact CPU assigns the input addresses for the A/B/N signals automatically according
to the configuration.
You specify the input addresses for DI0 and DI1 according to the table Interconnection
overview of the inputs (Page 108). The interconnection produces a direct connection of the
HSC to an input of the on-board I/O. The high-speed counter then uses this input as HSC
DI0 or HSC DI1 ([DI] symbol). The [DI] symbols in the table identify the input addresses for
HSC DI0 and HSC DI1 that are offered for selection in the hardware configuration.

Assignment of HSC addresses of inputs
You can find an overview of the options for interconnecting the inputs of the front connectors
X11 and X12 in the section Interconnection overview of the inputs (Page 108).
Digital outputs HSC-DQ0 and HSC-DQ1
Two digital outputs are available for each high-speed counter. Digital output HSC-DQ0 is a
logical output that cannot be interconnected with a digital output of the on-board I/O. Digital
output HSC-DQ0 can only be used via the user program. HSC-DQ1 is a physical output that
can be interconnected with a digital output of the on-board I/O.
The digital outputs are 24 V sourcing output switches relative to M and can be loaded with a
rated load current of 0.1 A. The outputs used as standard outputs have a rated load current
of 0.5 A. The digital outputs are protected against overload and short-circuit.
Note
It is possible to directly connect relays and contactors without external wiring. For information
on the maximum possible operating frequencies and the inductance values of the inductive
loads at the digital outputs, refer to the Technical specifications section.
The section Interconnection overview of the outputs (Page 109) provides an overview of
which digital outputs you can interconnect to which high-speed counters. Digital outputs to
which no high-speed counter is interconnected can be used as standard outputs. The
maximum output delay of each digital output used as standard output is 500 µs.When you use digital inputs/outputs with technology functions, i.e. interconnect high-speed
counters with the inputs/outputs, you must use shielded cables and the infeed element for
shielding.
