Configuration Guides—XT-9100 Configuration Guide 9
Via the GX Tool
The I/O type and map details are automatically generated by the GX-9100
Graphic Configuration Software when all I/O data for extension modules
has been entered. It is then downloaded into the XT-9100 directly or via
the DX-9100 and XT-Bus. (Refer to the Download/Upload section,
further in this document.)
When in the GX Tool, select the XT module, then define it as Analog or
Digital (if Digital, define it as 8 DI, 4DI/4DO, or 8DO). This defines
Module XP1. If an XT has 16 points (XP2 is connected), select the
XT box immediately to the right of the configured module, select
EXP.DIG and define it as 8DI, 4DI/4DO, or 8DO. “EXP” will appear in
the XT box. Then select XT (or EXP) again and define each point in the
selected configuration in the same way as when defining the points in the
DX-9100. The following pages describe how to define each of the points
individually.
Via the SX Tool
Each extension module configuration is defined by the I/O types and
map which are configured in Extension Module Items IOMAP (RI.77),
IOTYP (RI.78), and IOMOD (RI.79).
1. The I/O map (IOMAP) defines which inputs/outputs (in pairs) on the
extension module are used. Each extension module can be defined
with eight used points, which normally reside in the XP1 (first)
Expansion Module (points I/O1-I/O8), defined in bits X1-X4.
When an extension module has an XP2 (second) Expansion Module
with a further eight points, these points must be defined in bits X5-X8.
2. The I/O type (IOTYP) defines which inputs/outputs (in pairs) are
analog and which are digital. As the points on XP2 (if used) must be
digital, only bits X1-X4 can be configured.
3. The I/O mode (IOMOD) defines points as “input” or “output”
(in pairs). Only those points declared as “used” in Item IOMAP will
be monitored or controlled.
The combination of data in the Items IOMAP, IOTYP, and IOMOD
completely defines the configuration of an extension module. When
connected to a DX-9100 Controller, an identical set of data must be
entered into the Item data base in the DX-9100 Controller, so that,
when the DX-9100 and XT-9100 are connected and started up, the
DX-9100 will compare data bases and only send commands to the
extension module if the data is identical, thus avoiding incorrect
control actions.
