Just get the S7-200 226, the time difference actually does not support command BGN_LTIME, CAL_LTIME, the role of these two instructions can be obtained at any time of the time difference (ms), use very large But found no support for CPU 226 version 01.00-01.23 02.00-Ǣ.10 only support, I wonder if there is no way to upgrade.
