Step by Step Guide

Step 1 

Identify what your I/O configuration should be to communicate with your machine. (EX - Standard mode / Compatible mode / Mini IO assign, etc.) 


Step 2 

Using the full sized teaching pendant navigate to – IO -> Aux -> AlocMode. 



 

Step 3 

Select the configuration your machine was integrated with (Mini IO assign / Compatible / Standard, etc.). Select OK. 



Step 4 

Cycle power on your controller. Upon bootup the error should no longer be generated. Confirm robot controller / PLC handshaking works correctly. 



Step 5 

 If you continue to experience the 220F error, you may need to investigate having the controller repaired.  



Next Steps:

Use the RC7 Options Manual to confirm the I/O mapping of your machine & make note of IO setting on controller cover for future use.
