Asynchronous Message Thread; Asynchronous Commands - HEIDENHAIN MSE 1000 Operating Instructions Manual

Asynchronous message thread

MSEsetup has a thread that runs in the background and binds a UDP socket to the
asynchronous port. The asynchronous default port is 27300 and can be changed
in the Networking screen. This thread is used to accept asynchronous messages
from the MSE 1000 modules as well as from other client applications that want to
perform functions through MSEsetup.
Modules send broadcasts specifying their network information as well as
referencing complete, foot switch triggers, warnings, and errors.
The MSEvba.xlsm file is an Excel spreadsheet that is installed with MSEsetup for
demonstrating how to send asynchronous commands to MSEsetup using Visual
Basic for Applications (VBA).
