What is a resetting event?
A. The coding unit (CU) gets into the resetting event condition whenever a system reset condition occurs. The ESCON specification states that, when this condition is present, you reject any command that is not an x’02’ read or certain model-dependent commands. In that code, the CIP also accepts x’04’, x’e4′, x’84’, and x’03’. If the first command that is sent down for this device is not one of those, then the CIP presents a unit check and sets the resetting event indication in the sense byte.
