Simatic Fetch/Write - IEC 104

An ipConvLite gateway connects the Simatic S7 automation system to the IEC 60870-5-104 master station. All data areas of the Simatic S7-300 controller are accessed via the FETCH/WRITE interface. S7 communicates with the ipConvLite gateway by way of ISO-over-TCP (RFC 1006).
See also Communication with Simatic S7-300/400

The protocol Simatic Fetch/Write does not support the transmission of time stamps. However, the information may be time-stamped at gateway site. The gateway time can be synchronized with the master station via IEC 60870-5-104 protocol or over NTP (Network Time Protocol).

Our compact embedded controller MEC is used as hardware platform.
