34 Program features
The functionality of the base program is programmed using function blocks and
system inputs and outputs.
Sequence program is a state machine. This means that only one state of the
sequence program is run at a time. You can create a sequence program by
adding states and programming the state programs using the same program
elements as in the base program. You can program state transitions by adding
state transition outputs to the state programs. The state transition rules are
programmed using function blocks.
The number of the active state of the sequence program is shown by parameter
07.31 AP sequence state .
Control interfaces
 Programmable analog inputs
There are two programmable analog inputs. Each of the inputs can be
independently set as a voltage (0/2…10 V) or current (0/4…20 mA) input by
parameter. Each input can be filtered, inverted and scaled. AI1 can be configured
as DI3, AI2 can be configured as DI4 by parameter.

 Programmable analog outputs
There is one analog output voltage (0/2…10 V). The output can be filtered,
inverted and scaled.

Programmable digital inputs and outputs
There are four digital inputs, and one digital outputs (I/O that can be set as
either an input or an output).
Digital inputs DI3 and DI4 can be used as frequency input.
