PROTOCOLS
- Modbus RTU
- Modbus TCP/IP
An internal WEB user
interface for device mana-
gement: Connected devices
are deployed using the
Ouflex BA Tool.
Ethernet connection
(DHCP / Fixed IP), with Ac-
cess function.
Access is a service offered by
Ouman for creating a secure
VPN connection between the
device and the Ounet online
monitoring service. With the
service, the device can also be
operated remotely through an
internet browser. The service
is included in the price throug-
hout the device' s life cycle.
M-LINK is a media converter for converting Ouman's Modbus (RTU/
TCP) based devices, or those of other manufacturers, to the Ouman
system. Dynamic process diagrams can be done locally for the device,
which can be used to monitor the activities of the object smoothly.
Process images are created either with the OuflexBATool tool or di-
rectly via a browser on the device. The device can be linked to an exis-
ting internet connection, through which the device creates a secure
connection between M-LINK and the Ouman Ounet online
monitoring service.
If there is no internet connection, you can use, for example, an Ouman 4G modem,
which provides an immediate connection to the destination. M-LINK can be used at
the same time as an interface device to the Ounet control room, as well as locally from
the WEB user interface. The M-LINK WEB interface works over the Internet and local-
ly on a local area network without an Internet connection.
CONNECTIONS
•
Modbus RTU connection using screw connectors:
•
Modbus TCP connection RJ45
•
With a C connector (RJ45), it is also possible to
connect (one) Ouman controller (Ouflex M, Ouflex
M BA, S203, C203, H23) + GSM Modem when
using S203 or C203.
