Information:


Illustration 2 g00906513
(1) Power Terminal LocationConnect the power source to the terminal block at the back of the Panelview 1000. See figures 1 and 2.
Table 1
Model    Supply Voltage    Power Consumption    
PV1000G     18 to 32 DCV     40 Watts maximum (1.7 A at 24 DCV)    
PV1000C     18 to 32 DCV     50 Watts maximum (2.1 A at 24 DCV)    Table 1 shows the electrical ratings for the DC versions of the Panelview 1000 terminals. Electronic circuitry and an internal fuse protect the terminals from reverse polarity and overvoltage conditions.Note: The input power should be protected by a fuse or a circuit breaker that is rated at no more than 15 amperes.Note: The incoming power to the Panelview 1000 should be routed by a separate path from the communication cables. If the power lines cross the communication lines, the lines must cross at right angles. Communication lines can be installed in the same conduit as low level DC power lines (less than 10 volts).DH+ Terminal Connections
Illustration 3 g00911849
The DH+ versions of the Panelview terminals have a DH+ port and an RS-232 port. See illustration 3.Use the DH+ port in order to do the following communications:
Communicate with a PLC-5 controller on the Allen-Bradley DH+ link via the processor's DH+ port.
Communicate with an SLC 5/04 controller on the Allen-Bradley DH+ link via the processors DH+ port.
Communicate with a ControlLogix controller on the Allen-Bradley DH+ link via the 1756-DHRIO module.
Transfer applications over the DH+ link from a computer with a DH+ connection.Making DH+ Connections
Illustration 4 g00911895
Use a Belden 9463 twin axial cable (1770-CD) in order to connect a DH+ Panelview terminal to the DH+ link. See illustration 4.The DH+ link can be connected in the following two ways:
trunk line/drop line
daisy chainUse the following guidelines when installing the DH+ communication links:
Do not exceed 3048 m (10000 ft) of cable for a trunk line connection.
Do not exceed 30.4 m (100 ft) of cable for a dop line connection.
Do not connect more than 64 stations on a single DH+ link.DF1 Terminal Connections
Illustration 5 g00911983
The DF1 Panelview terminals have a single RS-232 communications port supporting DF1 communications. See illustration 5.
Illustration 6 g00912098
The DF1 port on the Panelview terminal is a 9-pin, male, RS-232 connector. Illustration 6 shows the pinout descriptions for the port and how these pins map to the DF1 ports on the controllers.The maximum cable length for DF1 communications is 15.24 m (50 ft)Ethernet Connections
Illustration 7 g00939939
The EtherNet/IP Panelview terminal can operate on an EtherNet TCP/IP network with the following devices:
Another EtherNet/IP Panelview terminal
Any device that can process CIP messagesThe EtherNet/IP version of the Panelview terminal has an Ethernet RJ45 communications port and an RS-232 serial port.
Use the RJ45 port in order to communicate with a logic controller on an EtherNet/IP network and use the RJ45 port in order to trasfer applications over an EtherNet/IP network.
Use the RS-232 serial port in order to transfer applications between a computer and the Panelview terminal by using a direct connection. The RS-232 serial port can also be
