(e) Set devices to be monitored by a GOT.
• Right-click the [ComEServerModbus*] file in the [ComEServerModbus*] folder in the logic POU under
the project tree and select [Insert] - [Cord worksheet].
• Set the variable devices to be monitored.
Instantiate Logic POU.Define an already defined instance to Task0.
• Right-click [Physical hardware] - [Configuration:IPC_33/FCX01:FCX/Tasks/Task0:CYCLIC] and select
[Insert] - [Program instance].
• Define the program instance name and select ComEServerModbus for the program type.
(f) Defining Target Setting
Define the IP address of STARDOM to set the communication settings.
Double-click [Physical hardware] - [Configuration:IPC_33/FCX01:FCX/Target Setting] and input the IP
address or the host name.
(g) Downloading the project
• Execute [Build] - [Make].
(Same as when pressing the function key F9).

dialog displayed when [Online] - [Project control] is selected.
• When the download is completed, select [Cold] and start STARDOM.

Device range
When performing monitoring with the GOT connected to a YOKOGAWA PLC and setting devices for objects, use
devices within the device range of the YOKOGAWA PLC.
When a device outside the range is set on an object, an indefinite value is displayed on the object.
(No error is displayed in the system alarm.)
For details on the device range of YOKOGAWA PLCs, refer to the following manual:
YOKOGAWA PLC user's Manual

Precautions
(1) For dual-redundant configuration
When STARDOM is configured with a redundant system, the connection is not supported.
(2) Not communicating with GOT and STARDOM in a specified period
When the GOT does not communicate with STARDOM in a specified period during the GOT is turned on,
STARDOM disconnects the line for the GOT. As the line is disconnected, the GOT displays an error when the
GOT monitors STARDAM after the disconnection.
After the error displayed as the system alarm (No.402: timeout error) on the GOT, the normal communication is
recovered and the GOT can monitor STARDOM.
