Making a DF1 Point-to-Point Connection
You can connect the MicroLogix™ 1100 programmable controller to your
personal computer using a serial cable (1761-CBL-PM02) from your personal
computer’s serial port to the controller’s Channel 0. The recommended
protocol for this configuration is DF1 Full-Duplex.
You can connect a MicroLogix 1100 controller to your personal computer
directly without using an external optical isolator, such as Advanced Interface
Converter (AIC+), catalog number 1761-NET-AIC, as shown in the
illustration below, because Channel 0 is isolated within the controller.
(1) Series C or later cables are required for Class I Div 2 applications.
ATTENTION
UNSUPPORTED CONNECTION
Do not connect a MicroLogix 1100 controller to
another MicroLogix family controller such as
MicroLogix 1000, MicroLogix 1200, MicroLogix 1500,
or to the 1747-DPS1 Network port using a
1761-CBL-AM00 (8-pin mini-DIN to 8-pin mini-DIN)
cable or equivalent.
This type of connection will cause damage to the
RS-232/485 communication port (Channel 0) of the
MicroLogix 1100 and/or the controller itself.
Communication pins used for RS-485
communications are alternately used for 24V power
on the other MicroLogix controllers and the
1747-DPS1network port .
