Mode
The station address for the serial port on the DF1 point-to-point network. Enter a valid DF1 address (0...254). Address 255 is reserved for
broadcast messages. The default is 0.
Enable Store Forward box should only be checked if the controller that you are downloading the project to is connected to the Master radio
modem. This particular controller will help support the radio modem network that is being created.
In the Error Detection section, click one of the radio buttons to specify the error detection scheme used for all messages.
BCC: the processor sends and accepts messages that end with a BCC byte. BCC is quicker and easier to implement in a computer driver. This is
the default.
CRC: the processor sends and accepts messages with a 2-byte CRC. CRC is a more complete method.
The SoftLogix controller has an RS-232 status indicator that follows
this behavior.
Indicator
Off
Green
Red
Please note that these status indicator states are different than for the
ControlLogix controller.
In this example, a workstation directly connects to a SoftLogix controller over a
serial device.

Use the Logix Designer application to configure the controller's serial port for the
DF1 Point-to-Point (full-duplex) protocol. This type of protocol supports
simultaneous transmission between two devices in both directions. The DF1
Point-to-Point protocol controls message flow, detects and signals errors, and
retries if errors are detected.
