• If you are running several overlapping subnets, you may want to consult your IT department to ensure that
the routing for the network is configured correctly
• If you are trying to access the camera through a gateway or a VPN router, verify that these devices are
configured such that they allow traffic from the iVu device to reach the destination device
15.10.3 Industrial Protocols Troubleshooting
Modbus/TCP Protocol
Modbus/TCP protocol relies on the fundamental TCP/IP connectivity to establish connections and transport data. After you
have verified Networking and TCP/IP connectivity, you should have little or no problems establishing a Modbus/TCP
connection.
iVu supports one Modbus/TCP connection from a single client, and will reject additional connection requests.
Prior to attempting to establish the Modbus/TCP connection, configure your device and teach it about the iVu device. Tell
the device the IP address of the iVu device that you have previously configured. Configuration steps vary for each device.
Consult the appropriate device manual for these steps.
The iVu Modbus/TCP port is fixed at port number 502.
After you have established a Modbus/TCP connection, verify that the iVu has accepted. Go to System > Communications >
Industrial Ethernet > Status , and view the connection status.

If you experience issues accessing data, see
(p. 152) for the Modbus/TCP register maps supported by the
iVu, and consult the Industrial Protocols Log. The log, when configured to Detailed Logging mode, provides a record of the
individual register access sequences and records any errors.

and PCCC Protocols
EtherNet/IP and PCCC protocols rely on Common Industrial Protocol (CIP

protocol to establish communications and
exchange data. CIP protocol, in turn, utilizes TCP/IP.
EtherNet/IP implements Input/Output (I/O) messaging. I/O messaging allows two devices, the iVu and the PLC, to
continuously synchronize data sets between each other. These data sets are called Input and Output Assemblies. The iVu
device consumes PLC output assemblies, and produces PLC input assemblies. This exchange occurs continuously, at the
rate specified by the RPI (Requested Packet Interval) value.
