If a MODBUS bus adapter card (optional equipment) has been installed into
Ouman EH-203 the controller can be connected to a browser-based user interface
through the Modbus bus using the EH-net.
The EH-net can be connected to the public Internet network or to the local network,
intranet. If the EH-net is connected directly to a public IP address, we recommend
using a firewall device between the EH-net and the network.
By using the browser it is possible to communicate with the EH-203 controller from
any pc. Information from the controller can be read and changed from the pc. If
desired, entry to certain functions can be limited or certain things can be hidden
that can be security risks or which are not relevant.
If the controller gives an alarm, alarm information can be transmitted by e-mail. If a
GSM modem is connected to the master device, alarm information can be
transmitted as text messages to a GSM phone.
Specific instructions for installing the MODBUS into the EH-203 controller and
initialization come with the bus adapter card. Instructions for network connections
and initialization come with the EH-net master device.
