Connection to Q170MCPU or Q170MSCPU(-S1)
Set [CPU No.] to "2" in the device setting to monitor the device of the Motion CPU area (CPU No.2).
When the CPU No. is set to "0" or "1", the device on the PLC CPU area (CPU No.1) is monitored.
When the CPU No. is set to the number other than "0" to "2", a communication error occurs and the monitoring cannot
be executed.
For setting the CPU No., refer to the following manual.

Connecting one PLC with multiple GOT units
When multiple GOT units are simultaneously accessing one PLC, the GOT writing process (transient/cyclic) and
reading process (transient) may slow down.
This slow access can be remedied with the following countermeasures.
<Countermeasures>
(1) Improve response speed on PLC side
Insert a COM instruction on the PLC to increase the response speed. Note that caution is required as the scan time
will increase.
(2) Screen design using cyclic devices
Create the screen with cyclic devices instead of using transient devices.
(3) Split GOT connection destinations into several systems
Add a master/local unit on the PLC side, and split the GOT connection destinations into several systems.
Improve the current system configuration.
(Example of current system configuration)
With the following system configuration, access from the GOT is concentrated at one unit.
