A CPU 214 with MLFB 6ES7214-1AD23-0XB0is annewer generationCPU, for which would you could find information on timers and counters in the following QuickReference guide: SIMATIC S7-200 Quick Reference Card CPU22x(see attached document). and the communications details in the following manual: S7-200 System Manualfor CPUs 22x: see chapter 7, Communications over a network. For older CPUs of the same family, such as the 6ES7 214-1CC01-0XB0consider the following manuals: SIMATIC S7-200 Quick Reference Card S7-200 Programmable Controller, CPU21x Hope this helps, Daniel Chartier Attachment S7-200 timers.jpg (272 Downloads)
