CONFIGURABLE FUNCTIONS
• Ensure that the set pulse width is as short as possible and as long as necessary for
the device connected to the digital output to still detect the pulse.
• Ensure that the duration of the pause between pulses is longer than the cycle time
resulting from the scan frequency (see "8.5 Scan frequency“ on page 61).
Behavior as switching output
The digital output is activated when the measured value falls below the set
lower limit
value or exceeds the set
upper limit
. The output remains active until the measured
value lies within the set limit values again.
If the measured values fluctuate about the upper or lower limit value, the digital output
would switch continuously. In practice, this behavior is not desirable. This is prevented
by the configurable
Hysteresis
.
• A small hysteresis increases the switching frequency at the limit value.
• A large hysteresis reduces the switching frequency at the limit value.

Analog module BAM100
The Bulkscan can read in and output analog current values in the range 4 to 20 mA via
the analog module.
Analog input signals are converted to digital format and transmitted to the Bulkscan.
The analog module can also convert measured values from the Bulkscan into analog
output signals and output them.
Three analog inputs are available, which can read in the following input variables:
•
Analog input 1: Belt speed
•
Analog input 2: Bulk density
•
Analog input 3: Mass flow rate
The analog module has four analog outputs, which can be assigned the following out-
put variables:
•
Volume flow rate
•
Mass flow rate
•
Center of gravity
•
Bulk height
•
Bulk density
•
Belt speed
The analog module must be ordered in addition to the basic device.
How to configure the analog inputs:
Switch to the
Measurement
tab.
Configure the reqired input source as
Analog value
Configure the
4 mA
point and the
20 mA
point according to the represented input
variable.
How to configure the analog outputs:
Switch to the
Interfaces
tab.
Click on
BAM100
to open the
BAM100
tab.
Select the assignment under
Analog outputs
.
Configure the
4 mA
point and the
20 mA
point according to the represented output
variable.
How to establish a connection to the BAM100 analog module:
Make sure that you have set and saved all of the application-specific settings.

Note
Close SOPAS ET and connect the Bulkscan to the BAM100 analog module with the
Ethernet connecting cable, see accessories (see "12.2 Accessories“ on page 77).
An RJ45 female connector is provided on the BAM100 module for this purpose (see
electrical installation).

Data interfaces
The Bulkscan has different data interfaces for the configuration and the transmission
of measured values.
It is only possible to output all measured values of a scan in real-time using the Ether-
net interface.
4.15.1
Ethernet interface
The Ethernet interface has a data transmission rate of 10/100 Mbit/s. The interface is
a TCP/IP interface supporting full duplex and half duplex.
The Ethernet interface allows the configuration of the Bulkscan as well as the output of
measured values.
The Ethernet interface is configured for DHCP as factory setting (automatic detection of
the DHCP server and retrieval of the IP configuration).
If your network uses static IP addresses, then you must adapt the configuration¬ of the
Ethernet interface so that a connected PC (client) can communicate with the Bulkscan
via Ethernet. If you are unsure about the correct Ethernet configuration, please contact
your network administrator.
Network
tab,
Interfaces, Ethernet
If you change the parameters for the interface via which you are connected to the sen-
sor, the connection to the sensor will be lost. You must re-establish the connection (see
"7.1.2 Establishing communication with the Bulkscan“ on page 50).
To connect the electrical interface, (see "6.2.3 Ethernet interface connection“ on page
4.15.2
Serial host interface
The Serial host interface is an RS-232/RS-422 interface. The host interface permits the
configuration of the Bulkscan and limited output of measured values.
The interface parameters are freely configurable.
Network
tab,
Interfaces, Serial, Serial Host Interface
group.
The factory setting for the host interface is as follows:
• 57,600 baud
• 8 data bits
• 1 stop bit
• No parity bit
The data transmission rate of the RS-232/RS-422 interfaces is limited to 57,600 baud.
Therefore these interfaces are not suitable for transmitting scan data in real time.
