If no control points are being auto - tuned, and then auto - tuning begins for con-
trol point 3, the contents of the corresponding word in the PC will change as
follows:
0000000000000000
When auto - tuning for control point 3 has been completed, the contents of the
corresponding word will return to 0000000000000000.
The status data showing whether an error has occurred in the E5ZE is
expressed in the contents of the corresponding word in the PC to which the
Master Unit is mounted.

This flag changes from 0 to 1 when the E5ZE power is
turned ON and DeviceNet communications are
enabled.
After checking that this flag is ON, execute the pro-
gram to start using I/O data.
This flag changes from 0 to 1 if the process value
exceeds 3200.0 F when a W/Re5-26 thermocouple
sensor is being used and the setting unit is 0.1 C/ F.
This flag changes from 0 to 1 if the output data from
the Master is not reflected in the E5ZE due to the
operating mode.
This flag changes from 0 to 1 if the remote I/O func-
tion has not been processed properly in the E5ZE.
This flag changes from 0 to 1 if there is an error in the
Temperature Controller, such as an AD converter
error or memory error.
This flag changes from 0 to 1 if the temperature sen-
sor is disconnected or short-circuited.
