RTC in S7-200?
- Thread starter supporter
- Start date
Well I went to the Siemens' Product Support web-site, I got a copy of the S7-200 System Manual, and I looked at Appendix A - Technical Specifications. It listed 5 different CPUs (S7-221, -222, -224, -224XP and -226) and gave the information about a real-time clock for each one.
And the info was [secret] 221 and 222: plug-in optional cartridge; 224, 224XP and 226: built-in[[/secret]
Oh come on, I've got to make you do something for this answer... !

Ken

Hi Ken, that's real neat! It still only took me about 2 secs to fathom out (guess!) how to make it visible though!
