Error code 0Eh is returned if the DL-DN1 is connected with any sen-
sor amplifier that does not support key lock or full key lock. (The set-
tings of such non-supported sensor amplifiers remain unchanged.)

• When normal
• When abnormal
The following tables list the command parameters used in explicit messaging to read/
write the settings and status of sensor amplifiers and to issue motion commands.
For details about how the master unit performs explicit messaging using command
parameters, see:
"Issuing a Motion Command to a Sensor Amplifier" (page 3-22)
"Reading/Writing Settings or Status of a Sensor Amplifier" (page 3-23)
Common command parameter list

65 Error status
The error status values of sensor
amplifiers (ID 01 to ID 04) are output
as they are assigned to bits 0 - 3.
R WORD 0
0: No error
1: Error
66 Warning status
The warning status values of sensor
amplifiers (ID 01 to ID 04) are output
as they are assigned to bits 0 - 3.
R WORD 0
0: No error
1: Error

Current value
property
This property is output by assigning
sensor amplifiers (ID 01 to ID 04) bits
0 - 3.
The output occurs when the measured
value is nonnumeric: "over," "under,"
or "invalid."
R WORD 0
0: Normally mea-
sured value
1: "over," "under," or
"invalid (-----)"
