Non–Sequence Protocol (ASCII In/Out and PRINT)
Configure the DL260 Port 2 for Non-Sequence
Configuring port 2 on the DL260 for Non–Sequence allows the CPU to use port 2 to
either read or write raw ASCII strings using the ASCII instructions. See the ASCII In/Out
instructions and the PRINT instruction in chapter 5.
In DirectSOFT, choose the PLC menu, then “Setup Secondary Comm Port.”
• Port: From the port number list box at the top, choose “Port 2.”
• Protocol: Click the check box to the left of “Non–Sequence.”
• Timeout: Amount of time the port will wait after it sends a message to get a response before logging
an error.
• RTS On Delay Time: The amount of time between raising the RTS line and sending the data.
• RTS Off Delay Time: The amount of time between resetting the RTS line after sending the data.
• Data Bits: Select either 7–bits or 8–bits to match the number of data bits specified for the
connected devices.
• Baud Rate: The available baud rates include 300, 600, 900, 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. Refer to the appropriate product manual for details.
• Stop Bits: Choose 1 or 2 stop bits to match the number of stop bits specified for the connected
devices.
• Parity: Choose none, even, or odd parity for error checking. Be sure to match the parity specified
for the connected devices.
• Memory Address: Starting V-memory address for ASCII In data storage.
