This System Configuration illustrates the use of the Tagged data design pattern to implement the Time-Stamped Messaging design pattern. As shown above, this system configuration is identical to that of the AGENTS_LOGL system, with the following differences:

• The LOG device is configured as a remote (RMT_FRAME) rather than a local (FRAME_DEVICE) device.
• The AGENTS device has an additional TAGS resource containing an instance of the TAGOUT FB type to forward messages from the MSG_LOG local multicast channel to the UDP multicast socket 225.0.0.1:1025.
• The LOG device has an additional TAGS resource containing an instance of the TAGIN FB type to forward messages from the UDP multicast socket 225.0.0.1:1025 to the LOG device's MSG_LOG local multicast channel, which forwards it to the LOG FB in its LOG_RES resource.
