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.
