Utilities - Upload/Download RTU Variables
Local register values can be uploaded (or saved) into a text file on a PC and then downloaded back into the
RTU. This is useful when an RTU needs to be cold-started or have new firmware loaded as the contents of
all the local registers are cleared.
Local registers (#R1 to #R2048), event log pointer registers (#YLLOGIDX1 to 255) and communication fail
(#YLFAIL) and success (#YLSUCC) registers can all be read from the RTU and saved to a file.
The register file is stored in tab-delimited ASCII format and can be edited using any text editor. When editing
the file, registers may be removed, added or have their values changed to any positive integer in the range
of 0 to 65535. Only registers remaining in the file will be downloaded into the RTU. Comments can also be
added to the file by beginning the comment with a semicolon (;). Comments can be inserted on new lines or
added to the end of existing lines.
Example:
• Select Upload RTU Variables to file and then choose a filename.
• If the file does not exist, Toolbox displays the window below. If the file does exist, then only the registers
specified in the file will be uploaded.
• After completing the cold-start or the firmware upgrade, select Download RTU Variables from file, then
choose the same file to download the registers back into the RTU.
Note: this function enables the user to overwrite local register values. If the logic includes things like
accumulated totals, edge triggers or register mapping, these may be overwritten or triggered when uploading
and downloading RTU variables.
Utilities - Enable / Disable I/O Scanning
An RTU will automatically attempt to scan all its IO modules at the configured IO Scan Interval
(Configuration, System Parameters). The RTU can freeze its inputs and outputs by disabling IO scanning.
Utilities - Enable / Disable Logic Processing
An RTU will attempt to processes its ladder logic at the configured IO Scan Interval (Configuration, System
Parameters). Processing of Ladder logic can be stopped by selecting Disable Logic Processing. The
status of logic processing can be viewed in the RTU Status. Note: the RTU Status will also display “Logic
Processing: Disabled” if the RTU does not have any ladder logic loaded or if ladder logic has been cleared
from memory (eg. after a cold start).
