Configuring The Electrical Modulebus; Db Elements For S800 I/O Modules - ABB Advant Controller 80 User Manual

Configuring the
Electrical ModuleBus
DB Elements for
S800 I/O Modules
4-16
As shown in Chapter 2, S800 I/O modules can be connected directly
on the AC 80 Electrical ModuleBus, or in I/O clusters via Optical
ModuleBus and TB820 ModuleBus modems.
S800 I/O module configuration data is set up in DB elements.
Each I/O module on the bus must have a dedicated DB element. The
element is selected according to the module type (e.g. DI810). The
terminal values of this element define e.g. the module position on the
bus. When the element is created, the inputs and output channels of
the I/O module are displayed as subordinate elements (e.g.
DI800_1.1). These are, in turn, connected to the PC section of the
application program by the programmer.
Figure 4-11 A DI810 element with its subordinate elements.
Item Designation: _1 refers to the first installed S800 digital I/O module.
Instance Name: User-definable (taken from the NAME terminal).
Callname: Module type.
Address (DI800_0.0.2.0.16):
2 refers to position (1 to 12); 16 is the number of the input/output (in
this case, 1 to 16).
Address (DI800_0.0.101.0.1):
101 refers to cluster 1, position 1 (max. 712 = cluster 7, position 12).
