The specifications for these Ethernet Units (CS1W-ETN21 and CJ1W-ETN21)
are compatible with those for previous models (CS1W-ETN01/ETN11 and
CJ1W-ETN11), so previous models being used with existing equipment can
be easily replaced by the new models. Many of the specifications for the new
Ethernet Units have been expanded, however, so there will be a number of
limitations if the Unit is simply replaced.
In particular, the CPU Bus Unit System Setup Area is formatted for the previ-
ous models, so there is no way to make the settings for the expanded specifi-
cations.
To remove these limitations, it is necessary to change the CPU Bus Unit Sys-
tem Setup format from "ETN11 mode" to "ETN21 mode." Refer to Changing
the CPU Bus Unit System Setup Area Format below for instructions on how to
make the change.
If the format change is from ETN11 mode to ETN21 mode, then there will be
no effect on previous applications. If the change is from ETN21 mode to
ETN11 mode, however, then certain limitations will go into effect.
The following table shows the limitations that apply when operating in ETN11
mode.
