Comms Repeat Rate (sec): (Continuous, 0.1, 0.2, 0.5, 1, 2, 5, 10, 30, 60) The rate at which Toolbox
generates a new message request. For example, when viewing the local registers with a Comms Repeat
Rate of 0.5 seconds, a read request for local registers will be sent every 0.5 seconds. If a message fails,
Toolbox will wait until the failed message has timed out (after Comms Timeout seconds) and then will send
the next message at the next 0.5 second time interval. When the Comms Repeat Rate is set to Continuous
or when downloading files (eg. firmware or configuration files) messages are continuously transmitted and
received without pausing between messages. Note: setting the Comms Repeat Rate to Continuous may
cause the PC or RTU to be overloaded with comms messages (especially if PC Port is set to Ethernet).
PC's Network Address (251-255): The PC is treated like another RTU when it sends or requests data from
an RTU and so the PC must have its own unique address. Addresses 251 to 255 are reserved for this
purpose. If two or more PCs are connected to the same RTU, each PC should have its own unique address
to avoid communication fails. Note: SCADA software (eg. Citect) may use address 255 by default and will
clash with Toolbox if Toolbox also uses address 255. Note: if the DNP3 protocol is being used in the
network, PC Network Address 251 should not be used. This is because DNP3 RTU addresses above 250
use the network list entry for RTU251.
Number Of Retries: (0-9) The maximum number of attempts (after the first attempt) Toolbox will have at
sending a message to the RTU if the previous attempts have failed. It is more reliable to set the Number Of
Retries to 1 or more when downloading an RTU Configuration or Ladder Logic over the network.
