Communicating with the FD-S series
- DeviceNet Compatible Network Unit DL-DN1 User’s Manual (FD-S) -
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 3-19)
 "Reading/Writing Settings or Status of a Se
nsor Amp
lifier" (page 3-20)
Common Command Parameter List
The table below describes command parameters which are common to the DL-DN1.
InstID: Instance ID; AttrID: Attribute ID
Attribute R: Read; R/W: Read/Write

64 Status
Bit 0-12: Unused

RWORD0*1
65 Error state
The error state values of sensor ampli-
fiers (ID 01 to ID 04) are output as 
they are assigned to bits 0 - 3.
RWORD0
0: No Error
1: Error
66 Warning state
Not used with the FD-S series.
RWORD0-
67 System reserved
68
Current value 
property
This property is output by assigning 
sensor amplifiers (ID 01 to ID 04) bits 
0 - 3. The output occurs when the 
instantaneous flow rate is non-
numeric: "over," or "invalid."
RWORD0
0: Normally mea-
sured value
1: "over" or "invalid"
69 to 6B System reserved
6C Error ID number
Error details. If there are errors with 
multiple ID numbers, the error infor-
mation for the smallest ID number is 
output.

74 Output 1
Output 1 is output by assigning sensor 
amplifiers (ID 01 to ID 04) bits 0 - 3.
RWORD0
0: OFF
1: ON
75 Output 2
Output 2 is output by assigning sensor 
amplifiers (ID 01 to ID 04) bits 0 - 3.
RWORD0

76 Output 3
Output 3 is output by assigning sensor 
amplifiers (ID 01 to ID 04) bits 0 - 3.
RWORD0
0: OFF

77 - 8C System reserved
8D
Current value 
"invalid"
If the instantaneous flow rate values 
for sensor amplifiers (ID 01 to ID 04) 
are invalid (-----), they are output by 
assigning them to bits 0 - 3.
RWORD0
0: Normal value
1: Invalid
