1.7 Miscellaneous Function Block
There are some other objects available which have not yet been discussed or mentioned
briefly in passing (i.e. constants.) These objects are not necessarily associated with one
another but are all discussed here.

have been mentioned in Section 1.3, Table 7.
These objects allow for additional data received on a CANopen® RPDO to be mapped
independently to various function blocks as a control source. The scaling objects are
provided to define the limits of the data when it is used by another function block, as
shown in Table 5.
Constant Values
Object 5010h
Constant Field Value
is provided to give the user the option for a fixed
value that can be used by other function blocks. Sub-index 1 is fixed as FALSE (0) and
sub-index 2 is always TRUE (1). There are 13 other sub-indexes provided for user
selectable values.
The constants are read as 32-bit real (float) data, so no decimal digit object is provided.
When setting up the constant, make sure to do it with the resolution of the object that will
be compared with it.
The False/True constants are provided primarily to be used with the logic block. The
variable constants are also useful with the logic or math blocks.
