We're an OEM looking to implement a system to require periodic entry of codes in the PLC to prevent machine shutdown. The codes will be supplied by us to the end user conditional on current payments. We use Allen-Bradley and AutomationDirect PLCs. Has anyone dealt with this? Any advice? Is there any literature anywhere toward implementing such a scheme?
Obviously I'll have to set the 'locked unless an exact copy of the program is present in the PC' condition and not provide the original program. We would also have to supply a 'final payment' code to disable this system.
