Module
DO_8
DO_0
Digital I/O modules can deliver both process data as well as additional
diagnostic information. Furthermore, they store the raw diagnostic data in the
input process image via 4 additional configuration modules. Three modules of
the respective input modules allocate 1, 2 or 4 bytes in the input image, 3
modules of the respective output modules reserve 1, 2 or 4 bytes in the input
and output image. Respectively, 1 module of the I/O modules is used to fill
previously reserved input and/or output areas. The 2 and 4 byte modules can
be found in the hardware catalog under the sub-category "Word / double word
module".
Module
DI_DIA_32
WAGO-I/O-SYSTEM 750
PROFINET IO
Description
Configuration module for 8 digital outputs,
1 byte is reserved in the output process
image of the I/O controller. The bit
information in the first byte is allocated to
the output data of the configured I/O
module according to the number of existing
signal channels. Remaining bit locations
(shown with a positive signal in brackets)
can be allocated to the signal states of the
following digital output I/O modules
having the same type of signal. This is done
by configuring the DO_0 modules of the
relevant I/O modules.
Configuration module for filling input
information previously reserved by
modules DI_32, DI _16 or DI _8. Care
must be taken that the number of previously
reserved output bits is sufficient to receive
the existing output information of the
configured I/O module (represented in
brackets with a negative sign).
Description
Configuration module for 32 digital inputs,
4 bytes are reserved in the input process
image of the I/O controller. The bit
information in the first byte is allocated to
the input and diagnostics data of the
configured I/O module according to the
number of existing signal channels.
Remaining bit locations (shown in brackets
with a positive sign) can be allocated to the
signal states of the following I/O modules
having the same type of signal. This is done
by configuring the DI_0- DI_DIA_0 or
DO_DIA_0 modules of the relevant I/O
modules.
