How can I see the entire program of a Model 50 and 30 CPU with SFW 50 and SFW 30 software when many of the rungs are unable to be displayed?
Even if the rungs can not be displayed with the SFW 50 or SFW 30 software, you can print the rung logic in Boolean format. By printing the program in Boolean you can now view the rungs that were not displayed in the software.
Note: The Model 50 and Model 30 Symax hardware and software are obsolete and there is no support on them. They can be upgraded to the M221 as the best solution for them. For more information on this you can contact Schneider technical support.
