Each NIO has eight sub-parameters for configuration. These are outlined in the FUNCTION BLOCK
OBJECTS & SUB-PARAMETERS section on page 2 and in the illustration above. Using NIO 105 as an
example:
10500=1
- Identify the remote controller node as # 1
10501=4
- Set NIO 105’s attribute as being an Analogue Input
10502=17
- Identify the remote controller object instance as # 17
10503=0
- For the purpose of providing Units to the NIO value, Identify the sensor type relating
to the object being read or written to
10504=0
- Configure as an input – NIO 105 will take on the value of controller 1 object
instance 17
10505=0
- No special value scaling required
10506=0
- No other point assigned to override (digital) the NIO or provide minimum limitation
(analogue) to the NIO output
10507=0
- No other point assigned to enable/disable (digital) or provide maximum limitation
(analogue) to the NIO output
Modbus Section
Enter MR to display the currently configured Modbus RTU register points, 153… 184.
Point Setting
Each Modbus register point must be configured including the Modbus device network address, the data
register address with in the device, the scaling value to match the register’s true reading and the
register data format to ensure the data is properly decoded and displayed.
All these elements are simply entered as a text string with comma (,) separators:
<Point #>
=
<Modbus Device Addr>
,
<Table #>
,
<Row #>
,
<Scaling >
,
<PointType>
(Address)
(AddHi) (AddLo) (SC)
(e.g. 4 [RIR])
Following this structure point 153 above would be entered with the following text string:
153=1,11,5,1,4
If the scaling is not yet decided then the scaling value can be omitted, or value 0 which is x1, and
included later as an
MRSC
nnn
=
command for each point that requires scaling as explained later in this
section.
