6 Commissioning
The bus coupler may only be commissioned with the entire system in which it is
installed.
Contact the system manufacturer if you want to commission the bus coupler.
u
6.1 First-time commissioning
Damage due to uncontrolled device movements!
The bus coupler and other system parts may be damaged by uncontrolled de-
vice movements.
Commissioning of the bus coupler may only be carried out in a pressure-
u
free state.

6.1.1 Making settings

The following prerequisites must be fulfilled:
• The transfer rate must be set the same for all DDL modules.
• The addressing conditions of the DDL (Drive & Diagnostic Link) must be ful-
filled.
• The DDL configuration must be set and tested.
• The terminating resistor after the last DDL participant must be connected.
Setting the DDL address
No DDL address has to be set on the bus coupler.
For the DDL (Drive & Diagnostic Link) to function properly, the following address-
ing conditions must be fulfilled:
• DDL address from 1-14, starting at 1, without gaps, no address assigned twice
DDL address 0: see DDL system description (R499050030).
Setting the transfer rate (DDL mode)
The DDL transfer rate is determined with the 5-pin S2 DIP switch on the front
side. All DDL participants must be set to the same transfer rate.

Table 3: DDL baud rate

S2 (5 bits) 5 DDL 125 kBaud
The transfer rate can be set as follows:
1. Open the cover of the S2 DIP switch.
2. Move the S2.5 DIP switch to the desired position. See g Fig. 5.
3. Close the cover of the S2 DIP switch.
Configuring the bus coupler
See section g 13.2. DDL participant parameters.
6.2 Starting the PROFINET interface
The bus system is connected using M12, 5-pin, D-coded data plugs. The physical
sequence of the devices in a PROFINET system can be chosen arbitrarily. The
X7E1, PROFINET (2) and X7E2, PROFINET (1) connections are therefore inter-
changeable and may only be configured when not in operation. See g Fig. 3.

6.3 Commissioning the VS with bus coupler
Before commissioning the system, the following steps must have been carried
out and completed:
• You have assembled the valve system and the bus coupler.
• You have connected the bus coupler.
See section g 5.2. Electrically connecting the product.
• You have carried out the presettings and configuration.
See section g 6.1.1. Making settings.
• You have configured the bus master so that it controls the valves correctly.
Assembly and commissioning may only be carried out by qualified
electrical or pneumatic personnel or an instructed person under the di-
rection and supervision of qualified personnel. See section g 2.4. Per-
sonnel qualifications.
Risk of uncontrolled actuator movements when the pneumatics are
switched on!
There is a danger of personal injury if the system is in an undefined state.
1. Put the system in a defined state before switching it on.
2. Make sure that no personnel are within the hazardous zone when the com-
pressed air supply is switched on.
3. Also observe the applicable instructions and safety information in the
VS operating instructions.
1. Switch on the operating voltage.
2. Check the LED displays on all modules.
3. Switch on the compressed air supply.

6.3.1 Start-up procedure

The start-up procedure is as follows:
1. The bus coupler automatically starts the communication with the DDL mod-
ules and determines which modules are present. At the same time, the
PROFINET controller informs the bus coupler of the configuration saved in the
controller.
2. The bus coupler checks the configuration and returns the following error mes-
sages where necessary:
– DDL address gap
– No DDL modules connected
– Fewer DDL modules connected than configured
– More DDL modules connected than configured
3. If an error is recognized, the bus coupler waits 5 seconds and restarts the DDL
communication. The user can then resolve the address error. See also sec-
tion g 6.1.1. Making settings. The DDL LED stays red in the event of an error.
If the error has been resolved, the LED extinguishes. See section g 13.2. DDL
participant parameters. The bus coupler uses the first valid configuration. Any
subsequent changes only take effect once the system has been restarted.
4. This information is used to created slots and subslots for PROFINET. The bus
coupler then waits for the parameters from the controller.
5. The bus coupler and PROFINET controller then both start the cyclical ex-
change of data.
