Isochronous-capable modules identification

Whether a module supports isochronous mode can be determined in the hardware catalog in
the following manner:
● When you select a device in the hardware catalog, you can see from the description in the
"Information" section whether this device supports isochronous mode or IRT.
Figure 5-1
● All peripheral modules that have the "HF" name suffix can be operated isochronously (e.g.
DI 16x 24 VDC HF - 6ES7 521-1BH00).
