Remote RTU
MASTER RTU1
REMOTE RTU2
REMOTE RTU3
• Once communications with the local RTU have been established (please see above), it is possible to
communicate with remote RTUs that are connected to the local RTU. This will only work if the local RTU
has been configured with the appropriate network links (please see the topic Configuration, Network List
for more information).
• Load the RTU configurations for the remote RTUs. If the configurations are not available, basic
configurations can be created in Toolbox (File, New) for each remote RTU. Only the address of each
new configuration needs to be updated to correspond to the address of each remote RTU
(Configuration, Address & Description). Configurations that correspond to the above network are
shown below.
• Toolbox determines which RTU to communicate with according to which configuration window is active
(highlighted or in front). As shown above, the configuration for Remote RTU3 is active. Toolbox will then
attempt to communicate with Remote RTU3 when commanded (eg. select View, RTU Status). All the
commands that can be sent to a local RTU can also be sent to a remote RTU.
• Comms fail: it takes longer to receive a reply to a message sent to a remote RTU. Toolbox may
timeout before the reply is received and flag a comms fail. To prevent comms fails, select Configuration,
PC Setup and set Comms Timeout to 5 or more seconds and set the Number Of Retries to 1 or
greater.
