6.2 Supervised system (Computer Supervisory System)

 (continued)

 

6.2.1 Supervised system with local addressing (through the track wheel)

 (continued)

 

Consequences of the local addressing mode 

(through the track wheel)

. Each device of the system must be addressed. 
. Addresses available: from 1 to 9 
. Address 0 not permitted 
It is possible to assign to several devices the same address with the purpose of grouping different functions, because they are related to the 
same electrical circuit. For example, it is possible to assign the same address to a signalling auxiliary module (cat. no 4 149 29), a universal 
control module (cat. no 4 149 32), a measuring module, and so on. In this way on the EMS CX

3

 display or in a supervision system the grouped 

function 

will be displayed as a unique “device” with all grouped functions. 

[

Refer to the scheme hereunder]

 

Note: In this configuration the Modbus address of an EMS CX

3

 module device or group of modules (several functions) is obtained considering 

the address of the interface Modbus/EMS CX

3

 Interface as tenth and the address of a device or group of function as unit (e.g. Interface address 

1 = 10 and device address = 5 

 Modbus address = 15) 

 

Consequences for the system architecture: 

-

 

for 1 IP/Modbus gateway (cat. no 0 046 89): 

o

 

up to 81 Modbus address 

o

 

mandatory limit of max. 9 Modbus/EMS CX

3

 interfaces or max. 1000 m of Modbus cable (cable Belden 9842, Belden 3106A or 

equivalent). 

-

 

for 1 Modbus/EMS CX

3

 Interface (cat. no 4 149 40): 

o

 

up to 30 EMS CX

3

 modules (ex. 30 devices grouped per functions with addresses from1 to 9) 

Note: with local addressing, the Modbus/EMS CX

3

 interface, does the automatic detection of modules (characteristics, functions, 

configuration...)
