CE123 - Base Unit

PLC TRAINER

Uses an industry standard PLC to control the PLC Process using ladder logic programming running on a PC. For use with the PLC Process (CE111).

The PLC Trainer shows students how to use a programmable logic controller. It also works with TecQuipment’s PLC Process (CE111) to help students study how to use programmable logic controllers to control a process. 

The clearly labelled front panel has all the input and output connections. Each input and output includes a socket and three push-button switches. One switch connects or disconnects the connection. The other two set the connection as permanently high or low to override the controller. This allows students to do some manual control, or add faults to see what effect it has on the process. Indicators show the status of the controller inputs and outputs. 

A socket on the front panel connects to a suitable computer (not included). The user must install the software (included) onto their computer so they can program the controller to suit their needs. TecQuipment supplies programs to match the experiments in the user guide (included). 

The software introduces students to the features of a controller program. These features include:

  • Normally open and closed contacts
  • Timers
  • Counters
  • Shift registers
  • Ladder logic
  • Simple programming
  • Ladder logic operations
  • Timers, counters and monitoring
  • Editing and adding comments in a PLC program
  • Special ladder logic instructions
CE111 - Experiment

Provides a physical system on which students can gain experience in the programming of programmable logic controllers (PLCs). The process is a model of a two-tank system typical of a chemical process in which liquids are measured before being mixed. The task for the student is to control liquid level and flow. For use with the PLC Trainer (CE123).
