Precautions for connecting to STARDOM
• Dual-redundant configuration
When the dual-redundant configuration is used with STARDOM, the GOT cannot connect to
STARDOM.
• System alarm
Programmable controller errors in the system alarm are not displayed.
• Clock setting of GOT
STARDOM does not have the clock data write/read function. Even though [Adjust] or [Broadcast] is set
for the clock setting, the setting is invalid (not processed).
When connecting multiple network devices (including a GOT) to the same segment
When multiple network devices (including a GOT) are connected to the same segment, the network load
may increase, and the communication speed may slow down between the GOT and a programmable
controller. The following actions can improve the communication performance.
• Use a switching hub.
• Use the high-speed 100BASE-TX (100Mbps).
• Reduce the GOT monitoring points.
When connecting GT16 to an equipment that meets the 10BASE (-T/2/5) standard, use the switching hub
and operate in an environment where 10Mbps and 100Mbps can be mixed.
Precautions on setup
When connecting a GOT to YOKOGAWA programmable controller, devices to be set for objects must be
in the device range of YOKOGAWA programmable controller.
When a device outside the device range is set for an object, an invalid value is displayed for the object.
(The system alarm is not displayed).
