English to Spanish Tech/Engineering IT (Information Technology)

Hello, I am translating an IT user manual and found this term: "broadcast attach" which is somewhat confusing to me.

The context I have is the following
Time after XXXX Broadcast Attach Messages
This parameter controls the time delay after XXXX broadcast attach messages.
By default, there is a 20 millisecond delay after the XXXX broadcast attach
messages. If the XXXX fails to read data from PLCs while the PLCs are running,
a longer delay is recommended to resolve the read request failure situation. You
can configure a longer delay value by defining a logical named XXXX_
BROADCAST_TIME.

TIA for your help!
