Thank you Best regards,

Basic (0BA7) The highlight of the 0BA7 basic devices is without a doubt the standard Ethernet interface, as a programming interface and for communicating with other LOGO! 0BA7 basic devices or SIMATIC automation components such as SIMATIC S7 CPUs, HMI Panels, and PCs. Standard Ethernet interface as programming interface and for communication with other LOGO! basic devices 0BA7 or SIMATIC automation components such as SIMATIC S7 CPUs, HMI Panels and PCs A maximum of 8 LOGO!s can be networked Data logging Standard SD cards as the storage medium Program and connection compatible with LOGO! 0BA6 Best regards, Shawn

ABN Posts: 212 Rating: (12)	hi, As you are concern about data logger, it depends on amt of data that is going to be stored. s7 300 or s7 400 along with WinCC can form one of the suitable option for data logger system. WinCC installed on Computer can store data (alarms and process values). In case if its requried to extend the storage capacity then in addition to WinCC, WinCC CAS or Storage plus can be added to configuration. Please post your exact process requirement to discuss more. All the best..

gre_m Posts: 947 Rating: (45)	Hi. I thing - Convenient to use CPU-3xx (such CPU312, etc...) - unattended data backup in the MMC card. Can use S7-4xx (it have big RAM)and archive data in RAM. But need for read archive data from PLC connection to external PC

ABN Posts: 212 Rating: (12)	hi, storing a data on RAM is not a simple task and it requires complex procedure. Also, amount of data which can be handled is also less. as, when data is to be stored on RAM it has to be stored along with Data and time stamp and process values and cosnumes more space for evet sample. This can be done using "AR_Send" and "AR_scan" block in s7 400. no blocks released for s7300 Hence, its advisable to store data on PC.

gre_m Posts: 947 Rating: (45)	Hi, If you register with a constant cycle, then the solution is much simpler: it is necessary to set a starting point. I log on in the ring buffer memory for some time before the event and its aftermath. fixed start recording and position in the ring. The data is then written off to the laptop using an application that uses Prodave. Further data can be processed by any program (such Excel). This solution can be used as a 3xx and 4xx CPU, depending on customer requirements. Using WinCC - it is an expensive solution
