28.4 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
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.
According to chapter
"Access code for service
(H5)", see page 126.
