Communication between several Excel 600 controllers is
possible only if the system bus submodule is plugged into
every computer module printed circuit board. This submodule
must be installed when joining several controllers, when
connecting a modem, or when monitoring via a central.
XD505A or XD508 can be used for local bus communication,
XDM506 is used for modem communication. A stand-alone
controller can be operated without a submodule.

CAUTION
Do not unplug the computer module with the power
still connected, since this could destroy the module.
First, switch S1 on the power supply module to the 0
position.
The XC5010C computer module contains both the system
bus and the field bus. Fig. 51 shows the pin-out of the
module.

The system bus is connected to terminal 16 (C+) and terminal
17 (C-). The field bus (L
ONWORKS bus) is connected to
terminals 12 and 13. The L
ONWORKS bus is non-polarized, i.e.
there is no + or – pin. See section "LONWORKS Bus Wiring"
(page 36) and "System Bus (C-Bus)" (page 37) for more
information.
