Operation
Main Module: Crestron KNX IO v3.1
The “Crestron KNX IO v3.1” module deals with the CGEIB-IP communication. The
module communicates via TCP/IP with the CGEIB-IP. To configure the module the
user should fill in the correct IP address and Gateway ID. The Gateway ID is used to
associate the IO module with other KNX data type modules in the program. Up to
500 KNX data type modules can be linked to one IO module This module is
ALWAYS required.
The Initialize input needs to be pulsed once to start the module. This is required to
connect the IO module with all KNX data type modules with the same Gateway ID.
Once the Initialization_is_Complete output latches high to indicate that the modules
are ready to be used.
The ConnectionStatus output provides feedback on the current status of the TCP/IP
connection with the CGEIB-IP.
Other functionality includes polling the value for all associated KNX data type
modules and enabling/disabling debug mode.
Debug mode should be turned off during normal operation.
Group Modules
Basically for every Group Address that needs to be controlled a KNX data type will
need to be inserted, no matter if it deals with control, feedback or both.
For every data-type (number of data-bits) there is a separate module. The principle is
however identical for all of them.. Every module has a parameter field that needs to
contain the Group address of the unit to be communicated with. Other signals and
parameters depend on the data-types.
The different types of Data Type modules
For every different data type in the KNX system (also called EIS type) there is a
specific Crestron module, this will allow you to send or read out any specific KNX
command or signal.
