Assuming we are talking about ibaPDA here, it is of course fully capable of cycle precise recording. Question is what Interface/Mechanism you use for the data acquisition? ibaPDA-Interface-S7-Xplorer ease of use is second to none, but you are at the mercy of the S7's OS to assemble the data and get them out to ibaPDA (as well as other factors such as CPU and network performance, if onboard CPU ports or CP's are used etc.)If cycle precise acquisition is required, you'll should at least go for ibaPDA-Interface-S7-TCP/UDP where your (cyclic) program is now put in charge of spitting the data out (although this one too depends on factors such as cycle time and network performance). If you want to err on the safe side, use an ibaBM-DP or BM-PN and acquire any and all real time I/O data directly from the bus as well as being able to send data out to the ibaBM device every cycle and grab them cycle precise that way. Suggest you head to www.iba-ag.com and download the "Customized Monitoring – S7 Controller Interfaces" brochure which will give you a good overview of the different ways iba offers to acquire data from S7 PLC's. |
