Hello all,
Require some urgent help on a project, apologies if poor explanation....
When CS1 CPU goes into stop mode in fault condition, eg fatal cycle time error, outputs retain in the state they were when CPU was stopped.
In code we monitor CPU status and turn output high to pull in relay to indicate CPU status normal to wiring circuit. But if CPU goes into stop mode relay remains energise as code is not running to turn output off?? Therfore for examples conveyors keep running...
How can we prevent this, can outputs be configured to go low if cpu stops? Any other ideas?
Any help will be appreciate, thanks.
