Communicate over Networks 31
Serial The RS-232 port is a non-isolated serial port built-in to the front of the
FlexLogix controller. You can configure the serial port of the controller
for these modes:
See:
• Logix5000 Controllers Common
Procedures Manual, 1756-PM001
Use this mode: For:
DF1
point-to-point communication between the controller and one other
DF1-protocol-compatible device.
This is the default system mode. Default parameters are:
• Baud Rate: 19200
• Data Bits: 8
• Parity: None
• Stop Bits: 1
• Control Line: No Handshake
• RTS send Delay: 0
• RTS Off Delay: 0
This mode is typically used to program the controller through its
serial port.
DF1 master mode control of polling and message transmission between the master and
slave nodes.
The master/slave network includes one controller configured as the
master node and as many as 254 slave nodes. Link slave nodes using
modems or line drivers.
A master/slave network can have node numbers from 0 to 254. Each
node must have a unique node address. Also, at least 2 nodes must
exist to define your link as a network (1 master and 1 slave station are
the two nodes).
DF1 radio modem • Compatible with SLC500 and MicroLogix1500 controllers
• This mode supports master and slave, and store and forward
modes
