27.4 Direction for communication on COM-loop
(H5/A3)
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.
(The communication direction is automatically changed two times per
24 hours, to ensure that the wires are okay.).
NOTE! The locking only works as long as you "see the text in the
menu A3", i.e. when you log out or if you are automatically logged
out, the communication direction will be "reset" to the normal
direction for that time.
