Explanation
Communication protocol of the bus system
Modbus Slave: For operation of the device as
a slave in a Modbus system
Modbus digital sensors: For operation of
digiLine sensors on the serial interface (see
order details for extra code "JUMO digiLine
protocol activated")
In the JUMO AQUIS touch P, either the inter-
face on the base unit or the optional serial in-
terface (if present) can be configured for
digital sensors (JUMO digiLine operation). Si-
multaneous use of both interfaces for JUMO
digiLine operation is not possible.
Transmission speed (symbol rate) of the serial
a
interface
For all bus users (device and digital sensors)
to communicate with one another, they must
have the same baud rate.
The baud rates of JUMO tecLine and JUMO
digiLine sensors are automatically set by the
JUMO digiLine master-device during the
scanning process.
When connecting digital JUMO ecoLine sen-
sors, the baud rate of the JUMO AQUIS
touch S must be set to "9600" prior to startup.
Otherwise, the sensors will not begin opera-
tion.
