CPU Specifications and Operation
In Direct SOFT, choose the PLC menu, then Setup, then “Secondary Comm Port”.
S
Port: From the port number list box, choose “Port 2 ”.
S
Protocol: Click the check box to the left of “DirectNET” (use AUX 56 on
the HPP, then select “DNET”), and then you’ll see the dialog box below.

Timeout: 800 mS
RTS ON Delay Time: 5 mS
Stop Bits: 1
Parity: None
Format: Hex
RTS OFF Delay Time: 2 mS
S
Timeout: amount of time the port will wait after it sends a message to
get a response before logging an error.
S
RTS ON / OFF Delay Time: The RTS ON Delay Time specifies the time
the DL05 waits to send the data after it has raised the RTS signal line.
The RTS OFF Delay Time specifies the time the DL05 waits to release
the RTS signal line after the data has been sent.
When using the DL05
on a multi-drop network, the RTS ON Delay time must be set to at least
5ms and the RTS OFF Delay time must be set to at least 2ms . If you
encounter problems, the time can be increased.
S
Station Number: For making the CPU port a Direct NET master,
choose “1”. The allowable range for DIrect NET slaves is from 1 to 90
(each slave must have a unique number). At powerup, the port is
automatically a slave, unless and until the DL05 executes ladder logic
instructions which attempt to use the port as a master. Thereafter, the
port reverts back to slave mode until ladder logic uses the port again.
S
Baud Rate: The available baud rates include 300, 600, 1200, 2400,
4800, 9600, 19200, and 38400 baud. Choose a higher baud rate initially,
reverting to lower baud rates if you experience data errors or noise
problems on the network. Important: You must configure the baud rates
of all devices on the network to the same value.
S
Stop Bits: Choose 1 or 2 stop bits for use in the protocol.
S
Parity: Choose none, even, or odd parity for error checking.
S
Format: Choose between hex or ASCII formats.
Then click the button indicated to send the Port configuration to
the CPU, and click Close.
