CGU 04i DESCRIPTION

2.4.5 User interface protocols
There are numerous industrial protocols implemented on the user interface:
•
ARNEP
UI
•
PROFIBUS
•
MBUS
•
MODBUS
•
AT
modem
•
SAUTER
•
IWKA
•
SBUS
•
RADOM
•
RDS
CONEL
New protocols, not supported by the communication module yet, can be implemented
according to the customer’s needs. CGU 04i module also enables the implementation of own
user protocol directly by the customer.
In case of M-BUS expansion board installed and when chosen protocol is not M-BUS
or M-BUS TCP then sent data will be returned back to the device! If e.g. LINE protocol is set-
up on this port, then data will return back to the source.
2.4.6 Sleep mode
On mounting module CNT – PORT2 the CGU 04i module contains voltage supply
management. During idleness the module CGU 04i is switched to sleep mode, when energy
demand is very slow (100
μ
A). Time of switch to sleep mode is programme adjustable. Module
wake up it is possible of status change on port.
