Creating output groups
An output group consists of a set of
SIPODs. To create an output group, follow
these steps:
1. Use either function code 6: preset single
register or 16: preset multiple registers.
2. The register addresses for output group
definition ranges from 256 (for output
group definition 1) to 380 (for output
group definition 125).
3. Assign the register value to create as
many output groups as desired. Note:
Each register is made up of two bytes:
the first byte represents the output
group number and the second byte is
the SIPOD number. For example, if the
register contains 0x0402, then the
output group is 4 (0-relative numbering)
and the SIPOD is 2. There can be
duplicate output groups and/or SIPODs
within the table. This means an output
group can contain more than one SIPOD,
and a SIPOD can be in more than one
output group.
Mapping input-to-output
By default, the factory assembled i-3
V2 Controller input-to-output mapping
is not set. Input-to-Output mapping can
be redefined as desired to meet the project
specification. To map input to output,
follow these steps:
1. Use either function code 6: preset single
register or 16: preset multiple registers.
2. Register address for input-to-output map
starts from 2048 for input terminal 1 to
2067 for input terminal 32.
3. Assign the register value for the desired
input maps. Note: Each entry (register)
in the table has two parts: a high order
byte that is either 0 (for an output
mapping) or 0x80 (for an output group
mapping), and a low-order byte that
specifies either an output (SIPOD)
number or an output group number.
The table is indexed by input number.
For example, if the fifth entry (register)
in the table is 0x0001, then input
number 5 is mapped to SIPOD 1. If the
tenth entry (register) is 0x8004, then
input number 10 is mapped to output
number 4.
Refer to Modbus Map table on page 14
for additional information.
Other configuration functions
Other functions, such as reading SIPOD
status, reading input status, setting up
SIPOD parameter, etc., are listed in the
Modbus Map table on page 14.
