Tag group rates and amount of tags

[pturmel]

• Tag group rates are targets, not exact, and do not have precise start times. They run at the best effort pace of their contents. You cannot control the "offset". Look at individual device status pages to see how closely the device is achieving the paces requested.

• Optimization is brand- and driver-specific. For modern Allen-Bradley, this discussion (and the links within) may be helpful:
