Precautions on system
Precautions for connecting to FA-M3
• For connecting the GOT to the programming tool interface connector with the CPU port/D-sub 9-pin
conversion cable, the GOT cannot connect to the F3SP10, F3SP20, F3SP30, and F3SP36.
• The F3SP10 is not applicable to the PC link module (F3LC11-2N). A GOT cannot connect to the
F3P10 via the RS-422 interface.
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 a GOT to the PC link module, connect a terminating resistor for the PC link module.
The GOT has a built-in terminating resistor.
The target device of an Ethernet cable differs depending on the Ethernet network system configuration to
be used.
Connect the cable to the system devices, including Ethernet modules, hubs, and transceivers, according
to the Ethernet network system to be used.
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.
Communication via network system
A GOT cannot access a programmable controller on the other networks via a programmable controller
(the network module, Ethernet module, and others) on the network where the GOT is connected.
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.
Precautions on setup
Set the switch of the PC link module before installing the PC link module on a base unit.
Polar difference between GOT and YOKOGAWA product
For signal names, poles A and B are reversed between a GOT and a YOKOGAWA product.
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).
