PROGRAMMABLE LOGIC CONTROLLER
(PLC)
This section discusses the setup procedures for the PLC (Programmable Logic Controller). The CX-1200
provides a basic PLC to compliment the motion control operation with I/O flexibility. The PLC allows you to
redirect or redefine the eight digital outputs and eight (of the 16) digital inputs. You can also use the PLC to
initiate a number of internal functions, or to test the state of status indicators. The PLC includes four timers,
four event counters, four latches, and four numerical comparators. The alarms are generated by the PLC.
The CX-1200 provides an editor for changing the PLC program without the need of a portable computer or
proprietary pendant. The program is presented as a text-based list of commands (instructions) and operands
(I/O, contacts, coils).
Caution: To avoid damage to your system, the CX-1200 must be calibrated and the motor drive set up before you
operate your system. Refer to Drive Setup / Calibration: Calibration.
