The Kingfisher OPC Server uses the native Kingfisher protocol to extract
data from the RTU. This is a more efficient method than the Modbus protocol because only changes in values are transferred.
Serial and TCP/IP are supported. Extraction of time tagged data from the RTU event log is also
supported.
Channel Configuration
| Protocol Mode |
Choose Protocol Mode |
| Master |
IOServer will initiate all requests. |
| Slave |
IOServer will wait for and response to
requests. |
Device Configuration
| System ID |
Sync character, use AE as default |
| Target RTU |
RTU for which this message is meant for. Use 0 for local
RTU. Only one Master device need to configured to access the local and
all remote RTU. |
| Initiating RTU |
RTU sending message. |
| Via RTU |
RTU to relay the message on to the target RTU |
| Poll Data Time |
How often to poll the update counter of each remote RTU. The
data from the remote RTU will be extracted if its update counter is
changed or when the data is first requested. The poll time for local
RTU is set by the group update interval of the OPC client. A value of
zero will disable data polls. |
| Poll Event Time |
How often to poll for time tagged data. A value of zero
will disable event polls. |
| Data Cache Time |
Request data from remote RTU if no data is received from
that RTU for the last Data Cache Time. A value of zero will disable
cache polls. |
| Write Mode |
Analog Data Write Function Code
| Send Multi Network Data |
Write to local RTU with FC 19 |
| Set Multi Data |
Write to remote RTU with FC 20 |
| QSet Multi Data |
Write to remote RTU with FC 23 |
|
| Event Index File |
The last event poll index is stored in this file. The
filename must be unique for each device. If this file is not
specified, then IOServer will extract all events from the RTU at
startup. |
| Timestamp Offset |
Add this number of minutes to all timestamps received
from KF RTU |
| Use GMT Time |
If Enable, all timestamp
read and written to the slave are assumed to be based on GMT time.
Otherwise local time is used. Use of GMT time is recommended, it is
the responsibility of each OPC client in different time zones to
convert the GMT time to local time for display. |
| Log SOE |
Enable the logging of SOE to ios.log File. |
Variable Types
Notes:
| %u(0-255) |
The prefix is the RTU number(0 to 255). Use 0 for the local
RTU |
| Log |
System Log. Read Only events |
| RTU |
The status for RTU N (0 to 255). 0 for offline, 1 for online.
The RTU is offline if the RTU Network Link Info 1, Last Fails register is
not zero. |
| A |
Analog I/O for module M (1 to 64) and channel C (1 to 8) |
| D |
Digital I/O for module M (1 to 64) and channel CC (1 to 16) |
| R |
Register N (1 to 2048) |
| RE |
Register Event logs (1 to 2048) will be redirected to RE.
Once any RE is read, register events will no longer to directed to R. |
| T |
Timer N (1 to 64) |
| Poll |
Write any value to this variable will cause all data to be
refreshed from the RTU. |
| Module |
Module Status Register N (1 to 64) |
| Monitor |
Inactivity Monitor N (1 to 4) of 8 registers each |
| System |
System Parameters N (1 to 64) |
| Clock |
Clock Registers. Write a 0 to any Clock register will set
the RTU to the current PC time. |
| Port |
Port Registers, Port 1 - 16 of 32 registers each |
| LI1 |
RTU Network Link Info 1. 8 registers for each RTU |
| LI2 |
RTU Network Link Info 2. 8 registers for each RTU |
| .%u(1-16) |
Bit 1 to 16 |
| Events |
Time tagged data from RTU event log are reported in the corresponding
variable with the time stamp information as received in the event data.
All received events are also log to the ios.log file. This feature
requires a minimum license size of 10,000 bytes.

Reading Long and Real
Device2.24R1,R4
Will read R1 and R2 from RTU 24 for Device2 as 32 bit real. A
real use two registers.
Device2.24R3,I4
Will read R3 and R4 from RTU 24 for Device2 as 32 bit long. A
long use two registers.
Device2.24R1
Will read R1 from RTU 24 of Device2 as 16 bit word
