The AG/DZ Expansion Module monitors the remote stations for bus inter
ruptions, power failure, and data transmission and passes the error mes
sages to the ZE.
The AG/DU has its own power supply which requires an input voltage of
24 V DC. The power supply provides the internal 12 V and 5 V voltages for
the input/output modules of the expansion station.
Connection The connection between the AG/DZ and AG/DU or between two AG/DU
modules is made using a shielded cable with connectors on both ends.
Addressing The AG/DZ module requires one input and one output address (byte ad
dress) in the basic unit. Address selection is made through a 8− seg
ment DIL switch (see paragraph 4.3.1 Digital Input Modules).
The AG/DU module requires no I/O addresses. Each expansion station
within the expansion line is allocated a station address (address range 0
− 3) which is set with a 2−segment switch on the AG/DU.
All available I/O addresses can be used in the expansion units. An ad
dress must not be allocated more than once within one expansion line.
Slot The AG/DZ occupies slot 7 in the GG301/301−K Basic Unit. The AG/DU
occupies slots 1, 2, 13, or 14 in the expansion unit, depending on the ex
pansion configuration, see paragraph 2.1.12.5.
