Functional Test of Digital Input Positioning

Positioning with Digital Inputs

 

 

4.5Functional Test of Digital Input Positioning

Normally you need a simple controller to set the digital inputs used to select the point table position entries, for example a PC, a mini PLC or an HMI control terminal. This chapter explains how you can perform a thorough check of the functionality of the positioning control functions without needing to perform the additional work of programming and installing a controller.

Fig. 4-19 shows a test installation without an external controller. Note that the FX Simulation Box used in this setup can set a maximum of 14 digital inputs.

NOTE

 

 

 

The test setup shown above does not use any safety features for the tests (EMG. OFF). You

 

 

 

 

 

 

 

 

 

 

should thus only use this setup in a controlled test environment where errors cannot cause

 

 

 

 

 

 

any danger for personnel or equipment!
