2.4 Address space
The CTEL master module can make available a total of up to 32 bytes for inputs and 32 bytes for outputs.
The precise number of the I/O bytes made available depends on the requirements of the connected devices.
I/O configuration presettings
The address space that the CTEL master module makes available and assigns accordingly in the CPX
system can be configured according to different presettings (
è
Tab. 2.4). These presettings correspond
to the selection options that are supported within the configuration files for the respective host system
(

For the CTEL master module there are 3 presettings available for operation as a “pure input module”,
a “pure output module” and for “mixed operation”. In addition, there is also a setting for operation
without connected devices.
