Appendix - Series I RTUs
Using Series I Communications With A Kingfisher PLUS+ RTU
A Series 2 RTU will respond to Series 1 messages when the port is configured with the S1 option (please
see the topic Configuration - Port List, Protocol) and the RTU has the Series 1 driver loaded. A Series 2 RTU
will also relay Series 1 messages if the port which the message enters the RTU on is configured as a Series
1 controller (S1 Ctrl). To relay a message from a serial port out of a radio port (eg. to relay an output
message from Citect), only the serial port needs to be configured as S1 Ctrl. The radio port can be
configured as S1 Outstn.
Communicating With Series I And Kingfisher PLUS+ RTUs
KIM software is used to configure and communicate with Series 1 RTUs. Since a Series 2 RTU is able to
relay Series 1 messages, KIM can be used to communicate through a Series 2 master to Series 1
outstations. It is then possible to carry out the complete range of commands and functions (as if KIM was
communicating through a Series 1 master) including downloading a KIM configuration to the outstation RTU.
A Series 2 RTU will respond to KIM's RTU Status command. The KIM RTU Status for a Series 2 RTU only
contains the RTU's current time and date with all other fields blank (if the battery voltage is zero, the
responding RTU is a Series 2 RTU). A Series 2 RTU will not respond to any other KIM commands such as
Get Single or Upload All so in order to read or write data to a Series 2 RTU, Toolbox must be used.
Series 1 RTUs are unable to relay Series 2 messages and so in order to use Toolbox to communicate with a
Series 2 outstation, the master RTU must be Series 2 or the PC must be directly connected to the Series 2
outstation.
Converting A Series I Configuration To Kingfisher PLUS+
Ladder Logic
Series I ladder logic can be converted to Series 2 format by loading and saving it with the Toolbox DOS
Ladder editor (please contact Semaphore for details). Since Series I only uses 8 digital channels which are
stored in the top 8 channels of the 16 channel ID, Toolbox increments all Series I ladder channels by 8. This
means that Series I digital channels 1 to 8 are converted to Series 2 digital channels 9 to 16 as this keeps
the digital data in the top 8 channels. Note: when creating new Series 2 ladder that is to be used to send
digital data to Series I RTUs, digital channels 9 to 16 should only be used as Series I is unable to access
digital data in the lower 8 channels.
Analog Inputs
Series I RTUs store analog inputs as a number in the range of 0 to 10,000 while Series 2 store analog inputs
as a number in the range of 0 to 32,760. When using a Series I analog input in a Series 2 RTU, care must be
taken to clear the bad value flag which is set when the analog input is <4mA (Series I RTUs set Ch16 of the
analog input value to ON if the analog input is bad). This must be done before the Series 2 ladder uses the
value because Series 2 will treat the bad value as a large value of 32768 (8000H) instead of as a value of
zero.
Digital Inputs
Series I RTUs store 8 digital inputs per ID (or register) and these are stored in the MSB of the ID (equivalent
to Series 2 digital channels 9 to 16).
