Honeywell Excell 500/600 Controll System 500-XCL5010 ユーザーズマニュアル

For information pertaining to system bus baud rates and 
termination switch settings, see section "C-Bus Termination 
(Excel 600)" on page 38. 

The XC6010 has 2 EPROMs for the operating system and 
one flash EPROM for the application software. Their locations 
are shown in Fig. 49. 

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. 

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

ON

W

ORKS 

bus) is connected to 

terminals 12 and 13. The L

ON

W

ORKS

 bus is non-polarized, i.e. 

there is no + or – pin. See section "L

(page 36) and "System Bus (C-Bus)" (page 37) for more 
information.
