8.2 Diagnostic Data
8.2.1 Cyclic diagnostic data of the UA-OFF monitoring board
The UA-OFF monitoring board sends the diagnostic message as a group diagnosis
with the input data to the bus coupler. The diagnostic bit for the corresponding
module (module number) indicates where the fault occurred. The diagnostic
message consists of a diagnostic bit that is set when the actuator voltage falls be-
low UA-OFF.
The diagnostic bit can be read as follows:
• Bit = 1: An error has occurred (UA < UA-OFF).
• Bit = 0: No error has occurred (UA > UA-OFF).
8.3 Parameter Data
The electrical UA-OFF monitoring board does not have parameters.
9 Presettings on the Bus Coupler
Configuration error!
An incorrect valve system configuration can cause malfunctions in and dam-
age to the overall system.
1. The configuration may therefore only be carried out by qualified personnel,
see section
g 2.4 Personnel
2. Observe the specifications of the system owner as well as any restrictions
resulting from the overall system.
3. Observe the documentation of your PLC configuration program.
The following pre-settings must be made using the PLC configuration program:
• Assigning a unique IP address to the bus coupler and adjusting the subnet
mask, see section
g 9.3 Assigning IP Address and Subnet Mask
• Setting the parameters for the bus coupler, i.e. writing the last byte of the
output data with the parameter, see section
rameters
• Setting the module parameters via the controller, see section
parameters for the modules
9.1 Opening and Closing the Window
Defective or improperly positioned seal!
Water may enter the device. The protection class IP65 is no longer guaranteed.
1. Make sure that the seal below the window (3) is intact and properly posi-
tioned.
2. Make sure that the screw (25) has been securely tightened with the correct
torque (0.2 Nm).
1. Loosen the screw (25) on the window (3).
2. Lift up the window.
3. Carry out the settings as described in the next steps.
4. Close the window. Ensure that the seal is positioned correctly.
5. Tighten the screw.
Tightening torque: 0.2 Nm

9.2 Changing the Address
An address change will not be effective during operation!
The bus coupler will continue to work with the previous address.
1. Never change the address during operation.
2. Disconnect the bus coupler from the power supply UL before changing the
positions of switches S1 and S2.
9.3 Assigning IP Address and Subnet Mask
The bus coupler requires a unique IP address in the Modbus TCP network in order
to be detected by the controller.
Address on delivery
On delivery, the switches are set to DHCP function (0x00). Switch S2 is set to 0
and switch S1 to 0.
9.3.1 Manual IP address assignment with address switch
See section
g 4.1.3 Address
The rotary switches are set to 0x00 by default. This activates address assignment
via DHCP server.
Proceed as follows during addressing.
1. Ensure that each IP address exists only once on your network and note that
the address 0xFF or 255 is reserved.
2. Disconnect the bus coupler from the power supply UL.
3. Set the station address at the switches S1 and S2 (g Fig. 9). For this, set the
rotary switch to a position between 1 and 254 for decimal or 0x01 and 0xFE
for hexadecimal:
- S1: High nibble from 0 to F
- S2: Low nibble from 0 to F
4. Reconnect the power supply UL.
The system will be initialized using the address defined on the bus coupler.
The IP address of the bus coupler is set to 192.168.1.xxx where "xxx" corre-
sponds to the setting of the rotary switch. The subnet mask is set to
255.255.255.0 and the gateway address to 0.0.0.0. Address assignment via
g 5.4.1 Setting
DHCP is deactivated.
The following table contains a number of addressing examples. See g Table 14.

9.3.2 IP address assignment with DHCP server
Setting the IP address to DHCP function
1. Disconnect the bus coupler from the power supply UL before changing the
positions of switches S1 and S2.
2. Once you have done this, you can set the address to 0x00.
DHCP mode is active after the bus coupler has been restarted.
Assigning an IP address
After you have set the address 0x00 on the bus coupler, you can assign it an IP ad-
dress.
