Configuring the Terminal Chapter 3

Communication Parameters

Sets the communication parameters for the DF1 port on the PanelView

terminal. The settings must match the target device. Each key press

toggles through the available combinations for:

• Parity = None (default), Even or Odd

• Data Bits = 8

• Stop Bits = 1 (default) or 2

The DF1 port on the PLC-5 controllers allows a parity of Even or None

parity with 8 Data Bits. For the SLC controllers, the parity is fixed at

None and uses CRC error detection.

Baud Rate

Steps through the communication rates for the DF1 communication

port with each key press: 1200, 2400, 4800, 9600, and 19200. The

initial default is 9600.The communication rate must match the

communication rate of the target device.

Error Detection

Specifies the type of error checking performed on data. The default is

Cyclic Redundancy Check (CRC).

• Block Check Character (BCC) - modulo-256 arithmetic sum of an

array of data bytes used for medium-level data verification.

• Cyclic Redundancy Code (CRC) - calculated on an array of data

bytes and used for high-level data verification.

Node

Specifies the node number (0…254 decimal) for DF1 network

communication. For point-to-point communication with an SLC, PLC,

MicroLogix controller or a 1761-NET DNI module, the default node

number of 64 is used.

When you press F4, the numeric entry scratchpad opens. Enter a node

number and press the Enter ↵ key. (On touch screen terminals, press

the ↵ key on the scratchpad.)

Handshaking

Specifies the type of handshaking used by the RS-232 port.

• On (CTS/RTS enabled)

• OFF (CTS/RTS disabled)

Press F5 or touch the box to select an option. The default is Off.
