There are communication ports on both UniStream HMI panels and CPUs.
UniStream HMI panels comprise:

• 2 Ethernet ports, RJ-45, 10/100MHz
• 2 Type A, USB ports, high speed
• 1 Type mini B USB port, high speed

Note that the Panel has its own IP address

UniStream CPUs comprise:

• RS 485

Note that the settings for the serial port allow you to enable MODBUS communications.

• CANbus

Note that the CPU also has its own IP address.
You can also add COM modules, available by separate order, to your Hardware Configuration.

• UAC-01RS2: one RS232 COM port.
• UAC-02RS2: two RS232 COM ports.
• UAC-02RSC: one RS232 and one RS485 COM port.

This is a partial list of the communications protocols are supported by UniStream PLCs. To see the full list, look within UniLogic itself, or check the UniLogic Help file:

• MODBUS RTU
• MODBUS TCP/IP
• CANOpen
• CANLayer 2
• UniCAN –Unitronics proprietary CANBus protocol
• FTP Server and Client
• SNMP V1/V2/V2c/V3
• Ethernet/IP

Third-party Protocols
You can use the Message Composer and the Third-party Protocol Ladder functions to communicate with virtually any external device, such as bar-code readers and printers
Use TCP Server /client in conjunction with the Message Composer for applications that require a proprietary Ethernet communication protocol.
Do not use this feature with built-in communication protocols offer by UniStream such as MODBUS.
You can set up to four (4) TCP Servers. TCP Server is dynamic in nature. Each Server can handle up to 16 simultaneous connections.
You can also configure the UniStream PLC as TCP client. When you add a TCP Client, UniLogic automatically creates a supporting Global operand struct.
The CPU Ethernet support up to 32 TCP server/clients and UDP sockets.
X: number of TCP servers; Y: number of TCP clients; Z: number of UDP sockets
X: <= 4
X + Y + Z <= 32
