5.2.5 ELOP II TCP connections to H41q/H51q controllers
ELOP II TCP can operate on an existing Ethernet network.
Requirements for using an existing Ethernet network for the HIMA PES with F 8628X
• Network may only contain switches
• Full-Duplex (no collisions)
• Sufficient bandwidth for transmission
• Calculating the timeout with the delay time induced by active network components
(e.g. switches, gateways) taken into account.
In case of direct connections (without switch) between the PADT and the H41q/H51q control-
ler, a "cross over" Ethernet cable is required.
5.2.5.1 ELOP II TCP connections to redundant H41q/H51q controllers
The PADT can establish a connection to the H41q/H51q
• only via channel 1 (left figure).
• only via channel 2 (middle figure).
• only via channel 1 (right figure).
5.2.5.2 ELOP II TCP connections to mono H41q/H51q controller
The PADT can establish a connection to the H41q/H51q
•either
via channel 1 or via channel 2 ,depending on F 8628X switch 2/1 (left figure).
• only via channel 1 (right figure).
