Direction for communication on COM-/BS4-
loop (H5/A3)
NOTE!
If the selected control unit number is an
EBL512 G3
unit in
a
mixed system
the function is different, see Operating Instructions
(MEW01473) for the EBL512 G3 system.
The communication direction is normally automatically changed
every minute, to ensure that the wires are okay all the way. To make
trouble shooting easier (e.g. during the commissioning) it is possible
to lock the communication on a COM or BS4
108
loop in one direction.
FAULT: No reply techn. no. xxxxxx
will be generated with a
reduced delay time. This function can be used to list all technical
numbers "behind" a loop cut-off.
NOTE!
Loop cut-off and short-circuit faults cannot be generated,
since they require communication in both directions at the same time.
The locking only works as long as you see the text:
COM-loop is currently communicating in A-direction
(
alternatively
B-direction
)
in menu A3.
When you log out or if you are automatically logged out (after 60
min.), the communication will start in the A-direction.
