input modules with transmitters:
81EA01-E/R1010
without correcting function
-2-wire transducer,4...20 mA,with supply from the module
-4-wire transducer,0/4...20 mA,with supply from the module
-4-wire transducer,0/4...20 mA,with external power supply
81EA01-E/R1111
with correcting function and without output of the uncorrected
value(raw value)
-2-wire transducer,4...20 mA,with supply from the module
-4-wire transducer,0/4...20 mA,with supply from the module
-4-wire transducer,0/4...20 mA,with external power supply

-2-wire transducer,4...20 mA,with supply from the module
-4-wire transducer,0/4...20 mA,with supply from the module
-4-wire transducer,0/4...20 mA,with external power supply
The module incorporates a total of 5 function units.Each
function unit may be used for any type of input mode.Any
combination is possible.The allocation as well as the settings
of all the parameters can be programmed easily using the
configuration list.The programmed values are stored in an
EEPROM to ensure that they are not lost in the event of a
power failure.They can be changed any time.
Every analog signal can be assigned up to 4 limit values.
In an input module,up to 5 independent correction or filter
calcuations can be carried out.Programming is done by
structuring function blocks.The conditions relevant to this
application are to be taken into consideration.
Features
The module can be plugged into any PROCONTROL station
with an external power supply unit.It is equipped with a standard interface for the PROCONTROL station bus.
The module sends the converted input signals in the form of
telegrams over the station bus to the PROCONTROL bus
system.The telegrams are checked before they are sent and
marked with test flags.This ensures that the receiving module can check them for error-free transmission.
The telegrams received over the station bus,e.g.for correction calculations,are checked by the module for error-free
transmission based on their test flags.
Provision is made to eliminate interference among the function units of the module and the station bus.
A short-circuit-proof and monitored transmitter power supply
is available for each function unit,suitable for the various
applications.
A response of the internal monitoring circuits or of the input
signal monitoring function is indicated in the form of a disturbance annunciation ST(general disturbance)on the front
panel of the module.
Application with analog transmitters
Types of transmitters
The function units of the module can be used for
-2-wire transducers,4...20 mA,with supply from the input
module
-4-wire transducers,0...20 mA and 4...20 mA,with supply
from the input module
-4-wire transducer,0...20 mA and 4...20 mA,with external
power supply of the transducer
For the applicable type of connection please refer to the connection diagrams.
For programming the application-specific settings please refer
to the configuration list.
Transducer power supply
The transducer power supply from the input module is shortcircuit-proof,coming from the respective supply output USn,
and is monitored inside the input module.
In the case of an external power supply for a transducer,the
supply contact of the function unit concerned remains free.
The maximum potential difference between the different reference potentials has to be taken into consideration in the
case of external power supply.
It is not admissible to connect several USn supply outputs in
parallel.
Analog signal input circuit and monitoring
At a high-accuracy measuring resistor,the input current signal is converted into a measuring voltage,connected to the
input instrument amplifier via a multiplexer and,after that,
converted into a digital 12-bit analog signal by an A/D converter.
The input instrument amplifier and the A/D converter are
monitored with the help of reference voltages.
The analog signals are monitored for plausibility inside the
module.The monitoring function responds as soon as an
upper limit(OG)or a lower limit(UG)is violated.
These limits can be modified in the configuration list.Their
default setting is 118.75%for the upper limit and-6.25%for
the lower limit.
Plausibility monitoring can be suppressed separately for each
function unit.For this purpose,the maximum values for the
upper and lower limits need to be entered into the configuration list.
The digital 12-bit signal is completed by the correct sign and
is sent by the input module as a telegram to the station bus.
As soon as the analog signal monitoring responds,the analog
value telegram will be sent with the disturbance bit set.
If an input is overloaded due to faulty circuitry,for instance,
the function unit concerned is switched off immediately.The
’Process channel fault’message in the diagnosis register and
the disturbance bit set in the data telegram indicate that a
fault has occurred in the function unit concerned.Every 30
seconds,there will be a new attempt to reactivate the disconnected function unit.
Application for correction and filter calculations
When being used for analog signal input,the following function blocks are provided on the module for correcting flowrate and level measurements,and for filtering measured
values:
-Correcting function for flow-rate KOR1
measurement for water/steam
-Correcting function for flow-rate KOR3
measurement for gases with variable reference pressure
-Correcting function for level measurement NIV
-Non-linear filter FIL
One function block can be used per function unit.
Function blocks KOR1,KOR3 and NIV contain the FIL function.
The function blocks include inputs for specifying the correcting quantity and the basic calculation values,and for issuing
the corrected value and the internal status messages via
outputs.The outputs of the function blocks for corrected values are assigned to the analog-value telegrams of the associated function unit.
In order to be able to carry out the correction,the inputs of
the function blocks must be assigned module inputs,signals
from the station bus,and fixed values.These are defined by
the user.
This procedure is referred to as structuring.The structure list
includes all of the information.This list is stored in the
EEPROM of the module.
The exact procedure of structuring the function blocks is
described in the function block descriptions.
For structuring,the following limit values of the module have
to be considered:
-Max.number of the function blocks 5
-Max.number of the signals from the bus 20
-Max.no.of function blocks per function unit 1
When function blocks are being used,the respective module
cycle time is increased by the specified computation time of
the function block.
The cycle time required for structure processing is calculated
automatically by the module and stored in the module register.It can be read there by the PDDS.
The corrected analog values are sent to the PROCONTROL
bus system in the form of a telegram.
In addition,it is possible to output the uncorrected raw values
as a telegram as well.
Telegrams for the function blocks,received from the bus,may
be disturbed and carrying a disturbance bit.The module uses
the value in this telegram for calculating and forwards the
calculated value as a telegram with a disturbance bit.
The module incorporates a monitoring function for cyclic
renewal of the telegrams to be received from the bus.If a
signal has not been renewed for a certain time(e.g.due to a
failure of the sending module),the receive monitoring function
in the module will repond.This function sets the disturbance
bit in the receive register allocated to the telegram.The module then uses the value transferred last with this telegram for
calculating and forwards the calculated value together with a
disturbance bit.
Application with analog transmitters
Types of transmitters
The function units of the module can be used for
-2-wire transducers,4...20 mA,with supply from the input
module
-4-wire transducers,0...20 mA and 4...20 mA,with supply

power supply of the transducer
