Communication speed auto-recognition
It recognizes communication speed when connecting
master. Communication speed is able to change only from
master unit.
After changing communication speed, re-supply the
network power to apply the changed communication
speed.
Network power voltage monitoring
● If
network power voltage is lower than the set value, the
network power voltage drop flag bit of Status bit is ON.
It can be read by Configurator or Explicit message.
●
Set monitoring voltage by Explicit message at Network
Power voltage (Set Value) of Application Object.
●
Setting range: 0 to 255
(factory default: 12V, Allowable range: ±1V)
※
Min. supplied power is 12V for ARD unit.
If network voltage is lower than 12V, the contents of
Explicit message reading is not guaranteed.
Unit power on total time monitoring
●
When total time for supplying power to the unit
becomes the SV, Threshold Run Hours Flag bit of
Status Bit turns ON. It can be read by Configurator or
Explicit message.
●
Set the time by Explicit message at Threshold Run
Hour of Application Object.
●
Setting range: 0 to 429,496,729 hours
(factory default: 876,000 hours),
Measured unit: 0.1 hours (6 minutes)
Unit comment
● You can set the comments for the unit (product
description) on network. It can be read by Configurator
or Explicit message.
● Set comment by Explicit message at Unit Comment of
Application Object.
● Setting range: max. 32 characters
Last maintenance date
●
It saves the last date of maintenance. It can be read/
written by Configurator or Explicit message.
●
Set maintenance date by Explicit message at I/O Last
Maintenance Data Setting of Analog Input Point Object.
E.g.) Data: 0x07DB020E→07DB (2011), 02 (Februray),
0E (14th)
Input conversion points setting
● Conversion cycle is changed by the number of points
(point, channel).
(conversion cycle: 1ms/point, when using 4 points,
it is 4ms). It can be read/written by Configurator
or Explicit message. After changing the number of
conversion points, re-supply the network power.
● Set the number of conversion points by Explicit
message at Number of AD Conversion Points Setting
of Analog Input Point Object.
● Setting range:
1 to 4-point
(factory default: 4-point),
conversion cycle: 1ms/1-point
Display scale
● Set high/low-limit scale value of analog input or output.
It can be read by Configurator or Explicit message.
Default
Scaling
Function Choice
: Scaling Flag bit ON
Scaling Type
: Default Scaling
(factory default)
It is set as 1,000 per 1V (mA).
In case of 1-5V, 4-20mA, it is
applied from over min. allowable
range 0.8V (800), 3.2 (3,200).
The below input value is break
detection. It outputs as min.
allowable range.
None
Scaling
Function Choice
: Scaling Flag bit
OFF
Scaling Type
: Default Scaling
It is set as default value 0 to
16000 (-8000 to 8000).
(0-5V, 1-5V, 0-10V, 4-20mA,
0-20mA: 0 to 16000, -5-5V, -10-
10V: -8,000 to 8,000 )
User
Scaling
Function Choice
: Scaling Flag bit ON
Scaling Type
: User Scaling
Set high/low-limit value to apply
at ‘Scaling Point 0%’ and ‘Scaling
Point 100%’.
Setting range: -28,000 to 28,000
