Error Cause Rectication

When an addi-

tional instrument

is connected, the

segment fails.

Max. supply

current of the seg-

ment coupler

exceeded

Measure the current consumption, re-

duce size of segment

Wrong pres-

entation of the

measured value in

Simatic S5

Simatic S5 cannot

interpret the num-

ber format IEEE

of the measured

value

Insert converting component from Sie-

mens

In Simatic S7 the

measured value

is always present-

ed as 0

Only four bytes

are consistently

loaded in the PLC

Use function component SFC 14 to

load 5 bytes consistently

Measured val-

ue on the display

and adjustment

module does not

correspond to the

value in the PLC

The menu item

"Display - Display

value" is not set to

"PA-Out"

Check values and correct, if neces-

sary

No connection be-

tween PLC and

PA network

Incorrect adjust-

ment of the bus

parameter and the

segment coupler-

dependent baud

rate

Check data and correct, if necessary

Instrument does

not appear during

connection setup

Probus DP cable

pole-reversed

Check cable and correct, if necessary

Incorrect termi-

nation

Check termination at the beginning

and end points of the bus and termi-

nate, if necessary, according to the

specication

Instrument not

connected to the

segment, double

assignment of an

address

Check and correct, if necessary

In Ex applications, the regulations for the wiring of intrinsically safe

circuits must be observed.

Error code Cause Rectication

E013 no measured value

available

– Exchange the instrument or send it

in for repair

E017 Adjustment span too

small

– repeat with modied values

E036 no operable sensor

software

– Carry out a software update or send

instrument for repair

E041 Hardware error, elec-

tronics defective

– Exchange the instrument or send it

in for repair

Error messages via the

display and adjustment

module

Fault message can also appear if the pressure is higher than the nominal

range.
