saved and exited. The tool may also be run at any time by using the ‘Validate’ button on the Modbus
Master main edit page.

The validation tool scans the current configuration, checking against a rule base which matches the INI
file reader in the Communication Interface. Each violation is listed on the validation tool window. There
is an option to ignore the errors and build the INI file with the errors still in the configuration. This
allows for partial configurations to be saved by the workbench before completion.
The rules used by the validation tool are listed below.
 All control registers used must be unique for all master and slave devices
 All status registers used must be unique for all master and slave devices.
 If a master is using Ethernet communications there must be a valid IP address specified which
is not 0.0.0.0
 No two master devices can use the same serial port.
 All slave devices connected to a common master must have unique station IDs.
 Two or more messages cannot write to the same application variable.
 Broadcast Mode control variables must be unique for all master devices
 When using single shot broadcast mode, a control variable must be defined.
 All statistics control and data variables must unique for all master and slave devices.
