DATA TRANSFER
The control and state reporting module transfers the information
about the state of the associated pulse operated latching relay or
CX³ contactor directly over the CX³ EMS bus and can thus be used
to bring up data to an operating system.
The coil of the associated CX³ device can therefore be controlled
remotely by the same operating system.
As seen on page 51 (paragraph «Viewing data»), information
is available on the mini configurator Cat.No 4 149 36, the touch
screen Cat.No 0 261 56, the Energy Management Software
Cat.No 4 149 38/39 and the Energy Web servers
Cat.No 4 149 47/48/49.
The Modbus register tables are made available for use by a system
integrator.
In this case, an CX³ EMS/RS485 Modbus interface is needed.
ADDRESSING
Addressing can be done:
• Locally on the product
- addressing from 1 to 9 using a selector.
• Via software
–addressing from 1 to 247
–the selector then stays on 0.
The CX³ EMS bus connection specifications are common
to all CX³ EMS products and are detailed in the product
data sheets.
Local setting using the selector takes priority over
software setting. In the event of malfunction, check
that the selector is definitely on zero.
