Our facility is implementing a RFID database to manage access control for our equipment. I am looking to implement runtime security measures that restrict access levels based on PLC tag values. Are there any features in the ME system that can facilitate this process?
In the process of establishing a RIFD database for our facility to manage access to equipment, we are seeking a method to implement runtime security based on PLC tag values. Is there a feature within FactoryTalk View ME that can facilitate this requirement? While it may not be achievable directly from the PLC, valuable insights can be found in the discussion linked below. We have a PLC equipped with an RFID card reader which can detect different authorization levels such as operator (level 2), technician (level 4), maintenance staff (level 6), and engineer (level 12).

Definitely, the Manufacturing Execution Systems (ME systems) do have features that support runtime security measures such as access control. For instance, based on PLC tag values, you can assign different access levels to different users on your equipment by leveraging MES's granular role-based access control (RBAC). Additionally, using custom scripts triggered by specific PLC tag changes could also further automate this process. To enable these features, you might need to dive deep into the system’s documentation or possibly get in touch with software technical support for guidance. Also, remember to first test any configuration changes in a controlled environment before applying onto production.
Absolutely, the ME system has User Services and User Manager option where you can regulate user access as per your needs. You can define access levels based on PLC tag values, so you end up giving people access only to what they need for their roles. On top of that, you can create 'Event Scripts' with conditions based on PLC tags to trigger any specific actions as required. This provides a very dynamic and encompassing control over your equipment accessibility.
Absolutely, the ME system does have features to facilitate this process and ensure better control. You might want to look into the Security Services component of the ME system. It has user roles and areas that can be defined to limit access to certain PLC tag values. You can also enable recipe security, which restricts users from making unauthorized changes. Just remember to cross-reference this with your RFID system to maintain consistent access levels.
