5.2.1 Overview of I/O Variable Addresses
5.2.1.1 Digital Inputs and Outputs
Module I/Os %IXy.z and %QXy.z
� I/Os of the basic module
� I/Os of the expansion modules which are attached to
the core Ventura Remote PLC unit by a ribbon cable.
Further configuration options are with the user who
integrates the appropriate expansion modules as
required. Module I/Os are mapped onto the process
image and refreshed between program cycles. Whereas
the basic module is accessed directly, the expansion
modules are accessed via a serial bus. To directly get the
signal states of the basic module, run function
FLUSH_INPUTS or FLUSH_OUTPUTS.
To view the addresses of module I/Os run the CoDeSys
PLC Configuration Editor.
I/Os are automatically addresses with respect to the
configuration.
