COM Ports and Data Communications
Information regarding the communications features of specific Vision models is
available from your local Unitronics distributor, or export@unitronics.com.
Below is a general description of Vision communication features. For details,
refer to the VisiLogic - Communications manual.
Com Ports
Serial
All Vision controllers comprise RS232 serial communication
ports. RS232/RS485 adaptors are available by separate order.
Certain models, such as the Vision120, support both RS232 and
RS485. For details on communications hardware settings, refer
to the User Guides and documentation supplied with relevant
models.
CANbus
Separate CANbus ports are built into specific controller models.
Ethernet
Ethernet ports are available by separate order.
Note
•
All ports can be used simultaneously. For example, a single controller
may use one serial port to send messages to a modem via RS232,
another port to communicate with a frequency converter, while the
controller engages in communications via its CANbus port.
•
Standard programming cables do not provide connection points for
pins 1 and 6.
Initializing COM ports
Serial and CANbus communication ports must be initialized in your control
program using the COM Init FB, located on the FB's menu.
The Ethernet port must be initialized using the Ethernet Card Init FB,
located under Ethernet on the FB's menu.
