Ouflex A is a DIN-rail-attachable and freely programmable device designed for monitoring, controlling and
regulating. The device is programmed with Ouflex BA Tool 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-mo-
dules via Modbus RTU connections.
You can move from one function to another by turning the control knob of your OuflexA 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 A device may be
hidden. 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 A
device. In this case, you can see the information even when
it’s locked, but you can’t make changes to settings without
entering the maintenance code. Normally, you lock the most
critical settings behind the maintenance code, or settings
that require expertise.
There is a symbol in front of a setting that requires main-
tenance code.

Setting the IP address using 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”, network settings were successfully chanced and
the device now functions in the network. Device IP address is
shown on display.

Connection satus Ouman Access OUMAN ACCESS – service enables you to make a remote connection
(useful with Ounet use) to Ouflex device from internet without any
extra hardware. All you need is a normal internet-connected LAN
with firewall and you have to ensure that certain ports to Internet
are open.
OUMAN ACCESS- service is “o” by default in Ouflex A.
OUMAN ACCESS- service is taken in use in following way: Ouman
salesperson feeds in the target and billing information to the Ouman
system and activates the service based on the serial number of the
Ouflex A 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 via Internet
The Access service operates on the Internet so the Access service is not
available if the device is not connected to the Internet. The Access device
examines the availability of Internet connection by sending a Ping packet to
the Internet server at 3-minute intervals.
The network must allow the ICMP outwards from any port and the receipt of
the reply message to the same port.
2. The VPN protocol used by Access service outwards is not blocked
The Access service is based on the VPN connection which the Access device
creates to the Access server.
The network must allow the UDP outwards from any port to the port 1194 and
the receipt of the reply message to this port.
3. Time service protocol outwards is not blocked
The Access service works only when the clock in the Access device shows
the correct time. The clock is set to the correct time automatically from the
network using the NTP protocol.
The network must allow the UDP outwards from any port to the port 123 and
the receipt of the reply message to this port.

Modbus TCP server settings are changed via Modbus TCP/IP settings.
It is possible to communicate with an Ouflex A device and the Mod-
bus/RTU slave devices connected to it via Modbus TCP/IP interface.
Modbus TCP port (internal registers): Port number 502 is reserved
for communication of Ouflex A device. Information of Modbus regis-
ters of Ouflex A device are read through this port. Recommendation
is that the value 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 the values 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 the value 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.

It is possible to connect three Modbus/RTU buses to an Ouflex A de-
vice. Each bus has its own port address that is used to communicate
with bus devices via Modbus/TCP interface. ”Modbus RTU master 1
(A1,B1)” setting defines the TCP/IP port for Modbus 1. Similarly, Mod-
bus RTU master 2 (A2,B2)” setting defines the TCP/IP port to Modbus
2. ”Modbus RTU master (RJ45)” setting defines the TCP/IP port that
functions as a gateway to Ouflex I/O extension bus. Gate addresses
can be changed.
SNMP settings: SNMP function can be used to send notifications
about alarms activating, inactivating and being acknowledged via
SNMP protocol to a desired server.
IP address: The IP address of the target server to which messages
are sent.
Function active: This selection either enables or disables the entire
SNMP function.
Retry delay (min): If the alarm is not acknowledged in Ounet, Ouflex
A sends SNMP messages again. The retransmission is limited to max
240 minutes. By setting the Retry delay to 0, the retransmission is is
disabled.
FTP
Ouflex A device support also FTP but read only mode. So cases this
can be use to read Modbus templates from device to Ounet.

If you take lock code into use, you can read Ouflex A device information
when the device is locked, but you can not change settings. It is recom-
mended, for example, that you take lock code into use if the device is
located so that anyone could reach it and change settings (e.g. deac-
tivate burglar monitoring). Locking the device and changing the lock
code prevents unauthorized use of the device.

Ouflex A device can be connected to Modbus RTU bus as a master or a
slave device. Bus settings are configurable. Every device connected to
the same bus must have unique address and same baud rate, number of
data bits, number of stop bits, and parity.
If a device is unstable on the bus, it may be possible to get the bus trac
stable by increasing the delay between the packets.
