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 3-23)
"Reading/Writing Settings or Status of a Sensor Amplifier" (page 3-24)
Common Command Parameter List
The table below describes command parameters which are common to the DL-DN1.

65 Error state
The error state values of sensor amplifiers
(ID 01 to ID 15) are output as they are
assigned to bits 0 - 14.
R WORD 0
0: No Error

Current value
property
This property is output by assigning sensor
amplifiers (ID 01 to ID 15) bits 0 - 14.
The output occurs when the measured
value is non-numeric: "over," "under," or
"invalid."
R WORD 0
0: Normally mea-
sured value
1: "over," "under," or
"invalid"

6C Error ID number Error details.
If there are errors with multiple ID numbers,
the error information for the smallest ID
number is output.

Comparator
value "invalid"
If the comparator values for sensor amplifi-
ers (ID 01 to ID 15) are invalid
(-----), they are output by assigning them to
bits 0 - 14.
R WORD 0
0: Normal value
1: Invalid
