Hi,

ten days now, i am looking throught the internet
to buy an S7-226. But i do not understand one thing.
Why the same products with the same technical
characteristics have different order numbers.
For example :
CPU 226 AC/DC/Relay 24I/16O---6ES7 216-2BD23-OXBO and
CPU 226 AC/DC/Relay 24I/16O---6ES7 216-2BD22-OXBO

Is there any problem when you are using PLC's
with different order numbers but the same series?

Thanks in advance.
