Open Transmission Control Protocol (TCP) ports

The table below lists the open TCP ports on the RMC. These ports are used for all TCP/IP based
connections which are supported by the Ethernet ports.
Protocols over TCP can be standard like SSH, or proprietary like Totalflow (Remote or Local).

Table 6-4: Open TCP ports on the RMC

Default User-
TCP port configurable
9999 Yes
65535 No
9696 No
502 Yes
IMPORTANT NOTE: For connections with user-configurable ports, use the default value or assign
a different port number from the range of 1024 to 65534. Connections using non-default TCP ports
are handled by additional Totalflow/TCP communication or Modbus TCP applications configured with
different TCP ports. For example, the figure below shows an additional Totalflow/TCP application
(named ControlGroup) with a different TCP port (10001).

Description
Serves connection requests for
secure login shell and file
transfer. Supports connection
requests from third-party
SSH/SFTP clients
Enables or blocks the ability of
the device loader to update the
embedded software.
Protocol using Description
the port
Totalflow/TCP Assigned to connections used for device monitoring,
configuration and data collection or polling. PCCU,
WinCCU, TDS and third-party SCADA systems request
these connections.
Device Assigned to the device loader connections for device
Loader/TCP software update.
PCCU requests this type of connection.
SSH/TCP Assigned to secure shell (SSH/SFTP) connections.
Third-party SSH/SFTP clients request these connections.
Modbus /TCP Assigned to connections between the RMC and external
Modbus devices for communication and data transfer
Security feature available
Authentication based on private-public key
pairs, passphrase-protected keys
None specific to the service. Must use Bi-
level security passcode or Role-Based
Authentication (Role-Based Authentication,
RBAC)
