In addition to the 24 VDC mains connection up to two of the following interfaces
are located on the back of the device:
•
DSfG
interface
•
COM2 interface: serial interface according to RS232. Intended for connect-
ing the modem for the integrated RDT (supported by C2 devices only).
Alternatively suitable for connecting proprietary protocols (Modbus RTU,
Modbus ASCII, RK512 or 3964R)
•
TCP/IP for integration in a standard network installation (for data exchange
via Modbus TCP or time synchronization via NTP)
Additionally, the C1 provides a slot for a
gas-net
process board (typically, a
serial process board MSER2 is installed here). A
gas-net
C2 device with a
mounting width of 1/3 accommodates up to four process boards.
The illustration below shows a typical rear view of a C2 device with a mounting
width of 1/3.
