Cleaning And Servicing; Software Diagnosis - Emerson AVENTICS PROFINET DDL Betriebsanleitung

6. In the event of an abort by PROFINET, the bus coupler then starts up again as
long as the parameters remain unchanged, as the DDL stack is only started
once with the transfer of parameters. In the event of changes to the parame-
ters, the bus coupler must be restarted.
7 In operation
Observe the following points for operation:
• Do not change the switch and configuration during operation. Changed set-
tings are only accepted once the device has been switched off and on again.
• Please note that compensating currents caused by differences in potential
must not flow via the shielding.
7.1 Diagnosis
7.1.1 LED diagnosis
On top of the housing, light emitting diodes (LEDs) indicate the status of the
PROFINET interface and the power supply. See also section g 5.2.2. Connecting
the supply voltage.

The power supply for valves is not monitored at the bus coupler.

7.1.2 Software diagnosis

The bus coupler provides diagnostic data:
Detailed information on the structures for diagnosis of the individual DDL partici-
pants can be found in the descriptions of the respective DDL participants.
Transmitting the diagnosis to the PLC can be inhibited by using the S1.1 DIP
switch.
S1.1 to 0 The diagnostic data will not be sent to the PLC (default).
S1.1 to 1 The diagnostic data will be sent to the PLC.
The warnings will be deleted automatically as soon as the cause has been elimi-
nated. Only one message can be displayed.
When making changes at the DDL, it is recommended to always con-
duct a voltage reset.

SF BF
Meaning
5 V: illuminates if supply voltage is > 18 V
DDL:
• Illuminates for configuration errors (address, baud
rate, terminating resistor)
• Illuminates during initialization and flashes after
successful initialization
• OFF during DDL communication
SF: System Failure
BF: Bus Failure
LINK0/ACT0: illuminated if a link exists, flashes when
sending and receiving data
LINK0/ACT1: illuminated if a link exists, flashes when
sending and receiving data
8 Disassembly and exchange
8.1 Disassembling the bus coupler
Damage can occur if the device is under voltage!
Inadvertently disconnecting the voltage can damage the product or system
parts.
Make sure the relevant system component is not under voltage before dis-
u
assembling the device or when disconnecting plugs.
1. Switch off the 24 V DC electronics power supply and valve supply.
2. Remove the connected plugs.
3. Loosen the bus coupler from the work surface.
4. Remove the bus coupler.
9 Disposal
Dispose of the product in accordance with the currently applicable regulations in
your country.
10 Maintenance and repairs

10.1 Cleaning and servicing

Damage to the surface caused by solvents and aggressive detergents!
The surfaces and seals could be damaged by solvents or aggressive cleaning
agents.
1. Never use solvents or aggressive detergents.
2. Only clean the device using a slightly damp cloth. Only use water to do this
and, if necessary, a mild detergent.
Check that all seals and plugs for the plug connections are firmly fitted so that
u
no humidity can penetrate the bus coupler during cleaning.
10.2 Maintenance
The bus coupler is maintenance-free. However, the seals of the bus coupler may
age faster under aggressive ambient conditions. Defective seals will lead to pneu-
matic leaks and non-compliance with the IP65 protection class.
1. Regularly check that the seals on the bus coupler are in perfect order. Estab-
lish the maintenance intervals according to your ambient conditions and store
them in the system-dependent maintenance plan.
2. Observe the system-specific maintenance intervals.

NOTICE
Remedy
Check the power supply to
the bus coupler.
Exchange the bus coupler.
Use tested cables.
Check the Ethernet cable and
PROFINET connections.
Check the baud rate, consec-
utive addressing 1-x, termi-
nating resistor present.
Check diagnosis on the par-
ticipants.
Adjust hardware configura-
tion.
