IO Configuration

General

The parameters of the I/O configuration determine which data of the I/O image are exchanged between Safety Logic Controller (SLC) and PacDrive LMC (Logic Motion Controller (LMC)).

The following table shows the connection between values of the I/O configuration and the I/O images:

I/O configuration	Corresponding I/O image
SLC2LMC_NumberOfBOOLs	SLC2LMC_BOOL
SLC2LMC_NumberOfBOOLsExt	SLC2LMC_BOOLExt
SLC2LMC_NumberOfINTs	SLC2LMC_INT
SLC2LMC_NumberOfUINTs	SLC2LMC_UINT
SLC2LMC_NumberOfUDINTs	SLC2LMC_UDINT
LMC2SLC_NumberOfBOOLs	LMC2SLC_BOOL
LMC2SLC_NumberOfBOOLsExt	LMC2SLC_BOOLExt
LMC2SLC_NumberOfINTs	LMC2SLC_INT
LMC2SLC_NumberOfUINTs	LMC2SLC_UINT
LMC2SLC_NumberOfUDINTs	LMC2SLC_UDINT

NOTE: The data configured in EcoStruxure Machine Expert - Safety must be used; otherwise Sercos cannot run-up correctly. For values of the data type BOOL or ExtBOOL, it is sufficient to use one boolean value per byte.

NOTE: The IO data is only configured once during project download. It can not be modified at runtime.
