•
KEY
Binary value number which can be selected under the binary value at
OP2 (binary value numbers 1 to 4 correspond to keys B1 to B4).
•
NAM
Designator for the binary value at OP2. If nothing is specified here,
then the following is displayed at the OP2: "SIGNALnn".
•
TRU, FAL
Designator for the logical conditions of the binary value at OP2
(TRU = True = Logical 1; FAL = False = Logical 0). If nothing is
configured here, then the following is displayed at the OP2: "0" and
"1".
There are two types of binary value function blocks:
•
One for setpoints
•
One for actual values

3.20.3.4 Message
output blocks (only OP2)
•
The message is directly output at an OP2 using a message output
block via the USS coupling.
•
A message is transferred, per broadcast, to all OP2 units connected to
the USS bus.
•
The message for display can be selected at each OP2. This selection
is made by configuring the message classes (prefix).
•
A maximum of 16 message output blocks can be configured (limited
by the number of broadcast channels for the USS coupling).
Data entry at the address input of a message output block:
AT:
"channelnam.1.99"
•
channelnam
Freely-selectable channel name (this must be unique on the
communications interface)
•
1
Address stage 1 = 1 signifies a special display device telegram (refer
to the Chapter, USS master coupling)
