BUS ADDRESS

Bus address
(binary coded, value selectable from 1 to 247)
DIP 1 DIP 2 DIP 3
128 64
O N O N OFF
Example shows 128 + 64 + 1 = 193 as Modbus address.
The device address in the range of 1 to 247 is set at DIP switch A.
For switch positions see table on the back!
Address 0 is reserved for broadcast messages. Addresses greater than 247 must not be assigned
and are ignored by the device. The devices are binary-coded with the following values:
DIP 1 = 128 ............ DIP 1 = ON
DIP 2 = 64 ............ DIP 2 = ON
DIP 3 = 32 ............ DIP 3 = OFF
DIP 4 = 16 ............ DIP 4 = OFF
DIP 5 = 8 ............ DIP 5 = OFF
DIP 6 = 4 ............ DIP 6 = OFF
DIP 7 = 2 ............ DIP 7 = OFF
DIP 8 = 1 ............ DIP 8 = ON
BUS PARAMETERS
Baud rate
(selectable)
9600 Baud
19200 Baud
38400 Baud
Reserved
Parity
(selectable)
EVEN-numbered
ODD-numbered
The baud rate (speed of transmission) is set at DIP switches 1 and 2 of DIP switch block B.
Selectable are 9600 baud, 19200 baud, or 38400 baud – see table!
Parity is set at DIP switch 3 of DIP switch block B.
Selectable are EVEN or ODD – see table!
Parity check is activated via DIP switch 4 of DIP switch block B.
Selectable are active (1 stop bit), or inactive (2 stop bits), i.e. no parity check – see table!
DIP switch 5 of DIP switch block B is not assigned.
Bus termination is activated via DIP switch 6 of DIP switch block B.
Selectable are active (bus termination resistance of 120 Ohm), or inactive (no bus termination) – see table!
When bus parameters and bus address are changed at devices with display,
the respective settings are shown on the display for ca. 30 seconds.
COMMUNICATION INDICATOR
Communication is indicated via two LEDs. Error-free received telegrams are signalized by the green LED lighting up.
Faulty telegrams or triggered Modbus exception telegrams are depicted by the red LED lighting up.
