Acyclic data communication
With acyclic data communication it is important to note that about 20 to 30 ms are required in order
to establish a TCP/IP connection. Following the successful establishment of a connection the ADS
data are sent or read. An ADS read of 1000 bytes takes about 50 ms. If no data are transmitted for
10 seconds, the TCP/IP connection is disconnected from the BC/BK9000, B/C900.
Register port 100
The ADS port number in the BK/BC9000, B/C900 for register communication is fixed, being set at 100.
