Serial interfaces

The UMG96S can have up to three serial inter-
faces, depending on the different available ver-
sion.

Profibus DP
RS232
RS485

These  serial  interfaces  are  not  separated  gal-
vanically. The RS232 and RS485 interface can-
not be used at the same time.
The  Profibus  interface  can  be  operated  at  the
same time with RS232 or RS485 interface.

Automatic recognition of the interface

If  both  interfaces  are  connected,  the  UMG96S
recognizes  by  the  signals,  if  a  device  is  con-
nected at RS232. The data transmission is car-
ried out via RS232.
If  no  device  is  recognized  at  RS232,  the  data
transmission is carried out via RS485 interface.

Interface selection (Addr. 062)

The selection of the RS232 and RS485 inter-
face is carried out on address 062:

0 = Automatic recognition
1 = RS232
2 = RS485

Modem operation (Addr. 070)

Via  RS232  or  RS485  interface,  the  UMG96S
can  be  connected  to  an  analogue  modem. To
enable  the  UMG96S  to  transmit  data  via  an
analogue  modem,  address  070  must  be
overwritten with the value 1.
Address 070 = 0 => Modem operation = No
Address 070 = 1 => Modem operation = Yes

The  connection  between  RS232  interface  and
analogue  modem  is  done  by  a  modem  cable
(option). The modem cable, part no. 08.01.503,
does  not  belong  to  the  contents  of  delivery  of
the RS232 interface.

Device address (Addr. 000)

If several devices are connected via RS485 or
Profibus interface, the master (PC or PLC) can
tell those devices by their device address only.
Within  a  network,  each  device  UMG96S  must
have its own device address.
Up to 255 device addresses can be entered.

Baud rate (Addr. 001)

For  RS232  and  RS485  interface,  the  following
common baud rate can be set.

Baud rate

: 0 - 9.6kBit/s
  1 - 19.2kBit/s
