9.2.3. Parameterization of the valve terminal with extension
terminal - bytewise composition of the inputs and outputs
The default value for the parameterization of the main terminal is:
• Extension terminal - none (must be adjusted bytewise on RIO)
• Input mode - normal inputs
• Filter - ON
When extension terminals are used the parameterization option extension terminals RIO bytewise must be
selected.
The parameterization can be used to modify the settings selected for the input mode and the filter.
Further, you may set the length of the device-related diagnosis, whereby the long diagnosis only makes sense
when more than four extension terminals are used. The following settings are permitted in the parameter telegram:
User parameter byte 11 User_Prm_Data
Input mode Input filter OFF Input filter ON Input filter OFF
long diagnosis
Input filter ON long
diagnosis
no inputs 05 hex 45 hex 85 hex C5 hex
normal inputs 15 hex 55 hex 95 hex D5 hex
shifted inputs 25 hex 65 hex A5 hex E5 hex
halved inputs 35 hex 75 hex B5 hex F5 hex
For a description of the input modes and the input filter refer to Section "9.3 Input modes".
9.2.4. Configuration of the valve terminal with extension terminal -
bytewise composition of the inputs and outputs
The settings of the desired configuration, i.e. setting of various identifiers, is generally done with the help of the GSD
file. Up to 18 identifiers (slots) can be assigned. Each extension terminal starts with a new byte in the process image.
For the main terminal and for each extension terminal 2 identifications are used, i.e. for bytewise configuration the
identifications for a single valve terminal must be contiguous. Each valve terminal can be configured with 4 input
bytes and 3 output bytes.
If there are no inputs / outputs present for a valve terminal, the identification 0 (space) must be entered
here.
Manual configuration: If no GSD file is available the configuration must be performed manually. The following
specifications apply:
