possible to select Data-INT, which will represent the data as 16-bit values, and Data-DINT, which will represent
it as 32 bit values.
I/O data is accessed in input instance 100 and output instance 150, so these values have to be entered as the
instance values for input and output. The size of the input connection and the output connection shall
correspond to the size that we have configured the Catalyst module for. In our case we are using 32 8-bit values
of input and output data, so that is the size that we enter. 32 in this case stands for 32 instances of 8 bits. If we
had been using Data-INT or Data-DINT, we would have to recalculate the size to match the data type, so Data-
INT would have been 16 16-bit values, and Data-DINT would have been 8 32-bit values.
The Catalyst module does not have a configuration assembly instance by default, but RSLogix5000 requires a
value for this anyway. An instance value of 0 is not a valid instance number, but any non-zero value will work,
here we have selected the value 1. The data size of the configuration instance has to be set to 0, otherwise the
configuration instance will be accessed and the connection will be refused. As a final step we enter the IP
address that we have configured for the module, here 10.10.14.225.
The next step is to press next.
