Nemo SX - Multifunction state module
Cat. N°:
SXMC02
6. SYSTEM ARCHITECTURES
6.1 Stand-alone system
(continued):
6.1.2 Stand-alone system with remote addressing (through a computer)
(continued):
Consequences for the system architecture:
-
for 1 mini configuration module (cat. no SXV01)
o
up to 30 Nemo SX modules (e.g. 30 devices grouped per functions with addresses from1 to 30)
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 multifunction signalling module (cat. no SXMC02), a
multifunction control module (cat. no SXM0C1), a measuring module, and so on. In this way on the Nemo SX display or in a supervision system
the grouped function will be displayed as a unique “device” with all grouped functions.
[Refer to the schemes here under]
Note for the mini configuration module (local display)
. It is possible to assign it the same address as another Nemo SX
. The mini configuration module can be placed everywhere in the Nemo SX bus
6.2 Supervised system (Computer Supervisory System)
. Supervised system = System to be used through a Computer Supervisory System to remotely read data from the Nemo SX devices and/or do
operations on these devices (e.g. commands of a motor driven or contactor ...).
6.2.1 Supervised system with local addressing (through the track wheel)
Local addressing advantages:
-
No configuration software needed to set-up the installation
-
Installation can be done without the intervention of a System Integrator
Programming procedure:
. For Nemo SX modules which need some: mandatory through the lateral DIP-switches of each Nemo SX
module
(see § ”Module configuration”)
Addressing procedure:
. For all Nemo SX modules: mandatory through the track wheel located on the top upper face of each Nemo SX
module
. Marked from 0 to 9 in order to locally define the Modbus address to Nemo SX
modules
In this system the Modbus address of a Nemo SX Nemo SX module device or group of modules (several
functions) is obtained considering the address of the interface Modbus/Nemo SX Interface as tenth and the
address of a device or group of function as unit (e.g. Interface address 1 = 10
→
address of module n°5 =
Modbus address 15)
Note for Measure Module “3x single phase”:
This module is to be consider as 3 modules with 3 different Modbus Address. The module takes automatically
the two addresses immediately following to the programmed one (e.g. Programmed address = 12, Addresses of
the module 12, 13, 14)
