Using the 1734-232ASC Module with the
ControlLogix System Application Examples
About These Examples
For these application examples, the 1734-PDN POINT I/O interface
was used to interface with the DeviceNet network. The 1734-232ASC
module acts as a normal slave to the master scanner. The data that is
sent to/from the scanner contains the ASCII data and some specialty
bytes.
Serial Port Connector
The ASCII devices are connected to the 1734-232ASC module via a
3-wire communications cable. The RX and TX designators are
referenced with respect to the 1734-232ASC module. SG is signal
ground.
