TR30-G USERS MANUAL EM-8631-G Rev.16
3.11.4 Modbus/TCP slave
By using the Modbus/TCP slave function built into the TR30, you can perform various operations including
online monitoring from outside.
• By setting the internal registers as [Enable], operations such as [Start/stop recording], [Start new memory
block] and [Comment insertion] can be performed from external devices such as PLCs.
• By setting the internal registers as [Enable], input values such as AI, DI and PI can be specified through con-
trol input from outside. Since an event can be triggered by this setting, commands for trend string insertion,
alarm output, and mail reporting can be issued to from remote locations.
(1) Set the [Configuration Select Switch] of the device as [TR30].
(2) Connect the PC in which TRGCFG is installed with the device, and start up TRGCFG.
(3) Click on the [Download from device] button.
(4) If the [Confirm access mode] is displayed, check that the device is correct, and click on the [Connect] but-
ton.
(5) Once the setting information has been loaded from the device, the [Configuration] is displayed.
