-- the self diagnostics of the CPU (see chapter 1.4.3, page 20) responds.
-- the supply voltage of the SIPART DR22 fails and the y
-- all modules except the power supply unit are removed (if the y
externally).
-- the y module is removed (Attention: electrostatically sensitive module! Observe the
hold
safety precautions!), if it is powered externally (error message on the front module
oP. *.6 Err/oP.*.5, see chapter 5, page 227). *.6 Err/oP.*.5, see chapter 5).
In this way it is possible to perform all maintenance work right up to replacing the instrument
whilst maintaining the controller controlled variable.
Handling during module replacement, see chapter 5 "Maintenance".
-- St Fault message output
This digital output is always high when there is no error and becomes low in the event of an
error. It responds when:
-- the self diagnostics of the CPU (see chapter 1.4.3, page 20) responds.
-- the controller power supply fails,
-- the Y module is removed,

-- the main board is removed.

6DR2803-8P Serial interface PROFIBUS-DP
The module 6DR2803-8P is a PROFIBUS-DP interface module with RS 485 driver and electri-
cal isolation to the controller. It operates as an intelligent converter module and adapts the pri-
vate SIPART to the open PROFIBUS-DP protocol.
This optional card can be inserted in all SIPART-DR controllers in slot 4. The following settings
must be made with the appropriate configurations for the serial interface:
-- Interface on
-- Even parity
-- LRC without
-- Baud rate 9600
-- Parameters/process values writable (as desired)
-- Station number according to selection 0 to 125
Make sure that the station number is not assigned double on the bus. The PROFIBUS module
serves to connect the SIPART controllers to a master system for control and monitoring.
In addition the parameters and configuring switches of the controller can be read and written.
Up to 32 process variables can be selected and read out cyclically by configuration of the
PROFIBUS module.
