9.1.2 Data cable
AS-Interface uses a geometrically coded, unscreened ribbon cable with a
cross-section of 2 x 1.5 mm
2
. It is used to transmit both power and all data
traffic between control and the peripherals and – to some extent – supplies
the connected devices with energy. The installation meets the usual require-
ments.
Engineering is simplified by full flexibility in system layout and mounting.
When a link is connected to the flat cable, two metal pins pierce through the
cable’s jacket and into the two cores to establish a contact with the AS-Inter-
face cable. There is no need to cut and strip cables, apply ferrules or connect
individual cores.
Rapid Link 5 function modules can be installed and removed any number of
times at various locations. The AS-Interface ribbon cable is self-healing, dust-
tight and resistant to sprayed water. The network can have a star, linear or
tree structure.
9.1.3 ASi profile
9.1.3.1 ASi profile with standard addressing range
•
RAMO5-xxxxA31… has the ASi profile S-7.4.
•
RASP5 has the ASi profile S-7.4
When using RASP5 and RAMO5-xxxxA31… units, a maximum of 31 modu-
les can be connected to (assigned an address on) a single AS-i line.
9.1.3.2 ASi profile with extended addressing range (RAMO5-xxxxA32…)
When using ASi slaves (A/B slaves) with an extended address range with ASi
profile S-7.A.E, an address can be assigned to a maximum of 62 modules.
Addresses 1A and 1B can be assigned for this purpose (maximum: 31A and
31B).
