Hi, First, you should stop thinking in tags...Since PCS7 V7.1, the license concept has changed. You should not worry about the amount of tags. The licenses are counted as PO=Process Objects. 1 PO is defined as follows: - a SFC or - blocks with one of the following properties: 1. Instance that can be controlled or monitored (s7_m_c attribute) 2. Instance that can generate alarms 3. Instance not part of the driver library You should not worry about instance DB's as they are generated by the FB. Since you are working with a CPU410, you must bear the following: The license concept when using this CPU is different from a normal CPU400. a CPU 410 is the most powerfull CPU, but you can scale it to your needs... The scaling is done by supplying the CPU with AS PO and should be at least the same amount as AS RT PO. Since you are using a redundant system, you have to buy the same amount of AS PO twice. So, if you have a system configured with 500 PO, you will need 2x AS PO (500 for each CPU). This will scale your CPU. Apart from AS PO, there are also AS RT PO. If you have configured 500 PO in your project (Go to Multiproject->Right click->PCS7 License Information), you have to have 500 AS RT PO in your ES station installed. When you download your project, 500 AS RT PO will be booked on the CPU. You don't need to buy them twice like AS PO. This will cover your ES station, but in order to work with a redundant server system, you will need to buy OS PO as well, which are installed on each server. So, you have 500 PO configured, you will need 2x500 OS PO (since you have a redundant server). Those are needed in order to operate the objects in runtime. You said you don't want to use APL. I highly suggest you will do. You have now learned that APL does not increase the license load on your system. APL is the newest library from Siemens. You can still use the classic V7.1 library, but that one is highly outdated and will not be updated anymore. See the following links for more information about the CPU410 and license concept: PCS7 Licenses and configuration limits Process Automation with the CPU410 Good luck!
