Function description
The terminal is designed for use within an Inline station.
This terminal is a fast two-channel input module used to
connect load cells, force transducers, mass pressure
transducers, and similar devices based on strain gauges.
The strain gauges can be connected using 6 or 4-wire
technology. The strain gauge output signals are measured
in each bus cycle and updated in the process data (bussynchronous process data update). The terminal is
designed for control system applications with increased
speed requirements.
Features
–
–
–
–
–
–
–
Two inputs for the strain gauges
Sensor supply voltage provided by the terminal, no
external power supply required
Connection of strain gauges in 6 and 4-wire technology
Communication via either process data or parameter
channel (PCP)
Channels are configured independently of one another
using the bus system
Bus-synchronous process data update
Diagnostic indicators
There are two options for data exchange:
– Via process data (both inputs in one bus cycle)
– Via PCP (both inputs in the "Analog Values" PCP
object)
The measuring values are represented by standardized
16-bit values.
A short circuit in the strain gauge supply at one of the two channels also prevents measured data acquisition
at the other channel for the duration of the short circuit.

Installation instructions
Unused channels
For unused channels, follow the instructions for
parameterization (see notes on bit 15 on page 15).
High current flowing through potential jumpers UM and US
leads to a temperature rise in the potential jumpers and
inside the terminal. Observe the following instructions to
keep the current flowing through the potential jumpers of
the analog terminals as low as possible:
Create a separate main circuit for the
analog terminals
If this is not possible in your application and if
you are using analog terminals in a main circuit
together with other terminals, place the analog
terminals after all the other terminals at the end
of the main circuit.

Connection examples
The IB IL SGI 2/F terminal can measure both unipolar and bipolar jumper differences. Observe the polarity
when connecting +Ud and -Ud.
If the analog terminal expects unipolar jumper differences, the signal excursion may be negative in the worstcase scenario. The measured value would therefore always be 0. In this case, adapt the signal excursion to
the input voltage range by switching cables +Ud and -Ud.
If the analog terminal is set to a bipolar jumper difference, the signal excursion may be mixed up in the sign bit
in the worst-case scenario. In this case, adapt the signal excursion to the input voltage range again by switching
cables +Ud and -Ud.
Connections +U0 and -U0 are led back to a unipolar input. If the cables are mixed up, the terminal indicates a
configuration error.

Read firmware version and module ID in IN2.
Configure device;
configuration for channel 1 in OUT2 and for channel 2 in OUT3
During the transient response (e.g., following a configuration command), the fluctuating measured values may
exceed the minimum and maximum values. Therefore, at the start of acquisition delete the minimum and
maximum values using command 3200hex and/or 3300hex.
One measurement is performed for each bus cycle.

The set bit ensures that the relevant channel is configured.
In the event that only one channel is used and there is no jumper supply at the other channel due to missing
wire jumpers, the configuration is acknowledged negatively in the status word. In this case, set bit 15 of the
configuration word of the unused channel to 0 to remedy the situation.
Filter
Selection of mean value generation. After every conversion, the measured value is saved in a mean value
memory via which the mean value is generated. The memory size can be selected with the filter option. E.g.,
for a 16-sample mean value, the mean value is generated using the last 16 measured values.
Character- Depending on the characteristic in relation to the available jumper supply, the terminal calculates the required
istic
gain for the configured input and thus has the best possible resolution in the unipolar and bipolar area.
If in the unipolar area the strain gauge is supplied with a load greater than 130% or a negative load, the
jumper detuning is outside the measuring range and an error is triggered.
If in the bipolar area the strain gauge is supplied with a load greater than 130% in the positive or negative
direction, the jumper detuning is outside the measuring range and an error is triggered.
If invalid parameters are specified in the parameter word, the command will not be executed. The command is
acknowledged in the input words with the error bit set.

Startup/measuring jumper detuning
To start the terminal, proceed as follows:
•
Install the terminal within the Inline station. To do so, proceed as described in the package slip.
•
Connect the strain gauge in 6 or 4-wire technology (see "Connection examples" on page 10).
•
Connect the voltage to the Inline station.
•
On this power up the terminal is configured with the default values.
•
If you do not wish to operate the terminal with the default values, configure the terminal via process data
(see "OUT process data output words" on page 14) or PCP (see "PCP communication" on page 18).
•
Jumper detuning can now be measured.
Jumper detuning can only be measured if the corresponding input is configured. To configure the input, the
jumper supply UV must be present.
16
Configuration and analog values
Terminal configuration is only required if at least one of the channels is to be operated outside the default values (see
"Parameters for configuration" on page 15).
You can configure the terminal either using process data or using PCP and transmit the analog values accordingly.
If you have configured the terminal via PCP, the configuration can no longer be modified using the process data.
For easy terminal configuration a function block can be downloaded at www.phoenixcontact.com.
Example 1: Configuring the terminal via process data
A strain gauge pressure force transducer for control system applications is connected to channel 1. Its data sheet specifies
a characteristic of +2 mV/V at a nominal load of 500 N. The following configuration is thus selected for channel 1:
Characteristic:
Filter:
Configuration value OUT2:
Channel 1
+2 mV/V
No mean-value generation
8002hex
A tractive and pressure force transducer with the characteristic ±4 mV/V at a load of 1 kN is connected to channel 2. The
following configuration is thus selected for channel 2:
Characteristic:
Filter:
Configuration value OUT3:
Channel 2
±4 mV/V
16-sample mean-value generation
8107hex
If both channels are operated in the default configuration, configuration is not required. When a configuration
command is sent, however, both channels will always be configured. Therefore also enter the corresponding
parameterization for the channel that is to be operated in the default configuration. If a "0" is transmitted for
channel 1 in bit 15 (do not configure, see bit 15 on page 15), the channel does not provide any values in the
following.
