Alternatively, you can assign SIMOTION to an I/O channel during the terminal configuration
(e.g. by selecting "DI (SIMOTION)", see Section SIMOTION D410-2 Configuring I/Os
(Page 208
)).
TO axis
The symbolic assignment of I/Os is also supported by the TO axis (e.g. for a HW limit
switch).
Substitute values for I/O variables
Substitute values cannot be specified for input variables of the BOOL data type. If you do
require substitute values however, proceed as follows:
1. Assign a digital input (e.g. SINAMICS_Integrated.Control_Unit.DI_8 [DI/DO 8, X121.7]) to
an input variable of the BOOL type (e.g. sensor).
2. Create a global variable (e.g. all_inputs) (at least data type WORD, e.g.
SINAMICS_Integrated.Control_Unit.DI_0_15).
3. Configure the substitute value
The corresponding bit of the substitute value must then contain the substitute value for the
BOOL variables.
In the same way, you can assign a substitute value to a BICO parameter.
For various SINAMICS drive objects, higher-level types are available for the assignment of
substitute values.
