Ouflex is a DIN-rail-attachable and freely programmable device designed for monitoring, controlling and re-
gulating. The device is programmed with OuflexTool utility and the prepared program is loaded to the Ouflex
device via Ethernet connection. It is possible to increase the number of I/O-points with external I/O-modules via
Modbus RTU connections.
You can move from one function to another by turning the control knob of your Ouflex device. By pressing
the control knob (= OK), you can enter any function to examine it in detail. This way you can see the related
measurements, state information, settings, time programs, etc.

Some of the information in your Ouflex device may be hid-
den. You can see the hidden menus by pressing OK for a
few of seconds. Similarly, you can hide them again by pres-
sing OK for a few of seconds. Hiding information that you
seldom need to change or look into makes the HMI simpler.
When visible, this information is shown indented.
There may be a maintenance code in use in your Ouflex de-
vice. In this case, you can see the information even when
it’s locked, but you can’t make changes to settings without

When Ouflex device starts up, it will automatically detect whether the
modem is connected or not and then initialises modem.
You may give your Ouflex device a device ID. In SMS communication,
always type the device ID in front of the keyword (e.g. OU01 MEA-
SUREMENTS).
Signal strength is expressed with description: ”Excellent”, ”Good”, ”Mod-
erate”, ”Low”, ”Very low” and ”Initialization failed”. If signal strength in-
dicates ”No network,” try changing the modem’s location or use an ad-
ditional antenna. If the signal strength is ”Very low” you should also
move the modem to another location to try to improve signal strength.
If the unit displays ”Initialisation failed,” check that the SIM card is cor-
rectly installed.
Approve: Press OK a number of seconds
Cancel: Press ESC a number of seconds

There are two alternative ways to set the Ouflex device IP address
and network settings:
1. IP address is retrieved via DHCP function. This requires that DHCP
service is in use in the network and network cables have been
connected.
2. IP address is set manually.

Both ways the set IP address are presented on the following page in
IP settings.
A network connection mode it is shown whether Ouflex device is in the
network or not. Ouflex device can be connected to a local network or
the Internet. If you use a protected VPN connection via OUMAN Access
service, the controller displays the network mode OUMAN Access.

Setting the IP address manually:
1. Go to DHCP and press OK.
2. Select ”O” and press OK to accept selection. If DHCP function is
on, manual changes in ”Subnet mask”, ”Gateway address”, ”Name
server address” and ”IP address” will be ignored.
3. When set IP-settings manually you need to ask correct settings in
that LAN admimistarator.
OBS. Never try to guess the correct settings. Incorrect settings
cause problems, and the network is work properly.
4. Enter the gateway IP-address first
5. Enter the subnet mask address
6. Enter the IP-address
7. Enter the name server IP-address

DHCP Off >
Gateway adress 0.0.0.0 >
Subnet mask 0.0.0.0 >
IP address 0.0.0.0 >
Nameserver address 0.0.0.0 >
IP settings
Setting the IP address via DHCP function:
1. Go to DHCP and press OK.
2. Select ”On” and press OK to accept selection.
3. Wait approximately one minute. If DHCP is still ”O” after one minute,
setting the IP address and network settings was not successful. Eit-
her the settings used previously or factory settings have been taken
in use. In this case, the device does not necessarily function in the
network. The reason for this is usually that the required DHCP ser-
vice is not in use in the network, or it is out of order, or the network
cables have not been connected properly. Check the network cable
connections and/or make sure DHCP service is in use.
4. If DHCP is ”On”, device give notification to display it’s new IP-ad-
ress. Then IP address and other network settings was change suc-
cessful. The device now functions in the network.

OUMAN ACCESS – service enables you to make a remote connection
(useful with Ounet and Ouflex Tool use) to Ouflex device from internet
without any extra hardware. All you need is a normal internet-con-
nected LAN with firewall and you have to ensure that certain ports to
Internet are open.
OUMAN ACCESS- service is “o” by default in Ouflex. OUMAN ACCESS-
service is taken in use in following way: Ouman support feeds in the
target and billing information to the Ouman system and activates the
service based on the serial number of the Ouflex device. After that, you
have to activate the ACCESS service from the device.
OUMAN ACCESS- device can be connected to LAN if following condi-
tions are fulfilled:
1. LAN is routed to internet
2. The VPN ports used by ACCESS are not blocked
1. LAN is routed to internet
Access –service uses internet. Therefore it is available only if the local
LAN has connection to internet. ACCESS-device examines the availabi-
lity internet connection once per minute by sending a ping-package to
a server in internet.
Network has to allow ICMP towards internet and also allow the
response message to come back to Ouflex.
2. The VPN ports used by ACCESS are not blocked
ACCESS-service is using VPN to the internet connection.
Network has to allow UDP communication from any port towards
port 1194 in internet and the responces from that port back to
Ouflex device.

Modbus TCP slave (server) settings are changed via Modbus TCP/IP
settings. It is possible to communicate with an Ouflex device and the
Modbus/RTU slave devices connected to it via Modbus TCP/IP interfa-
ce.
Modbus TCP port (internal registers): Port number 502 is reserved
for communication of Ouflex device. Information of Modbus registers
of Ouflex device are read through this port. Recommendation is that
they should not be changed unless there is a compelling reason.
Max connections: It is possible to decrease server load by changing
this setting that defines the maximum number of simultaneous con-
nections from dierent IP addresses to the server. Recommendation is
that they should not be changed unless there is a compelling reason.
Idle timeout: This setting defines the time after which the server clo-
ses an inactive connection. Recommendation is that they should not
be changed unless there is a compelling reason.
Allowed address: It is possible to improve the information security
of the system by taking permitted connection address into use. If the
value is 0.0.0.0, connections to the server are permitted from any IP
address. If you define one permitted connection address, connections
to the server are not permitted from any other IP address.
Function active: This selection either enables or disables the entire
Modbus/TCP communication.

Port 1 (2,3) number: It is possible to connect three Modbus/RTU
buses to an Ouflex device. Each bus has its own port address that
is used to communicate with bus devices via Modbus/TCP interfa-
ce. Port 1 setting defines the TCP/IP port that functions as a gateway
to Ouflex I/O extension bus. Ouflex device is located in Modbus 1 in
address 1.
Port 2 defines the TCP/IP port for Modbus 2 (A1,B1). Similarly, port 3
defines the TCP/IP port for Modbus 3 (A2,B2).
SNMP settings: SNMP function can be used to send notifications
about alarms activating, inactivating and being acknowledged via
SNMP protocol to a desired server. If the SNMP trap reception does
not ack back from Ounet to device, Ouflex sends SNMP messages
again The retransmission is limited to max 240 pieces. By setting a
setting value of RetryDelay to 0, the retransmission is not performed.
IP address: The IP address of the target server to which messages
are sent.
Active: This selection either enables or disables the entire SNMP function.

Ouflex device support also FTP but read only mode. So cases this can
be use to read Modbus template files fron device to Ounet.
Two Ouflex devices can communicate with each other at the level of
IP by using Modbus TCP protocol. In this case, two Ouflex device may
have common points. For example, the outside temperature measure-
ment, or the emergency stop switch can be common. Here you can see
what is in the name of the device, IP address and port number.

If you take lock code into use, you can read Ouflex device informa-
tion when the device is locked, but you can not change settings. It
is recommended, for example, that you take lock code into use if
the device is located so that anyone could reach it and change set-
tings (e.g. deactivate burglar monitoring). Locking the device and
changing the lock code prevents unauthorized use of the device.
1.7 Backup
It is recommended to make a backup as soon as Ouflex has been ta-
ken into use and property-specific settings have been made. Five
latest backups can be restored to the device. You may also restore
factory settings.

Ouflex can send an alarm for a number of dierent reasons. Infor-
mation about the alarm is shown on the display. The alarm also
sounds a beeping noise.
If the regulator has a number of unacknowledged alarms and you acknowledge
the last one, the one before it will appear on the monitor. When all active alarms
have been acknowledged, the alarm window closes and the alarm sound stops.
All active alarms can also be quiet by pressing the Esc key. The alarm windows
close when you press the Esc key only once.
OBS. Notice at this is not same as acknowledgement of alarm.
From alarms you can see the cause of the alarm, where the alarm has come from
and when the alarm has become inactive. (e.g., 02.11.2014 at 10:11:42). The last
10 alarms can be seen in Alarm history.

The present value shows what is the status of the control just now.
When the automatic control is in use, it is shown in the display,
what is state of the control according to the time program at the
moment. Control command can be either a weekly schedule or ex-
ception schedule.
When you press the ”Present value” line OK, Ouflex-device asks for a
service code. After entering the service code, you can change the cont-
rol mode (automatic/ manual). This way you bypass time program and
force the control to the desired mode. When the manual control is in use,
the hand symbol appears on the front of the line.
In Ouflex, weekly programs can be added to dierent functions
- such as temperature drops, car heating and control of lights. In
your Ouflex device, you can find time programs under the clock
symbol and/or under the function that a time program has been
made for (e.g. heating control, car heating, control of lights, control of
electric groups, routing of alarms).

There may be fields that you can rename in your Ouflex device. You
often download an application where general names have been gi-
ven to the controls, and you may want to rename them more accu-
rately.

”Room 1”, ” Room 2”, etc. You may want to give them more accurate
names. In control of electric groups, you may want to rename ”Electric
group 1” and ”Electric group 2” more accurately, depending on what
you actually control with the relay in question.
