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.
