Precautions - Mitsubishi Electric GOT1000 Series Connection Manual

2.7 Precautions


Program control device
• When Program Execution Command (0), Program
Exit Command (2), or Program Restart Command (4)
is written to the program control device (PRG 0), it
will be a request for all programs running in the
controllers.
• When unsupported write data is input to the program
control device, the following error is displayed in the
system alarm.
315: Device writing error.
Correct device.

Variable devices
The variable number 99 of Integer device and variable
number 199 of Real device are special devices used for
operations by the X-SEL controller system. Do not use
these variables for general purpose.

Command trigger compatible device
• For the device whose obtained data No.0 is a
command trigger, communication with the controller is
performed when the Write(1)/Read(2) is set to the
command trigger. When the command trigger and
setting value are written in a batch, the
communication is performed based on the value set
with batch write.
• When Clear(4) is set to the command trigger, the
communication with the controller is not performed
and the set value is initialized.
• When an unsupported set value is input to the
command trigger, the following error is displayed in
the system alarm.
315: Device writing error.
Correct device.

Device reserved for system use
Devices of "Reserved for system use" are devices with
indefinite values. Do not write to these devices.

Write to the flash ROM
• The point data can be written to the flash ROM of the
X-SEL controller. When the point data is written to the
flash ROM, it is not cleared even when power supply
to the controller is turned off. However, there are limits
in the number of writing. For details, refer to the user's
manual of X-SEL controller used.
• Never turn off the main power supply during the flash
ROM write. Doing so may cause the loss of data and
malfunction of controllers. For details, refer to the
user's manual of X-SEL controller used.

Communication disconnection
• Writing to the flash ROM disconnects the
communication with controllers until the writing is
completed.
• Resetting software restarts the controllers. During this
time, the communication with controllers is
disconnected.

Station number setting of the IAI robot
controller system
The robot controller with the station number set with the
host address must be included.
2.4.2 Communication detail settings

Connection of the IAI X-SEL K type
Note the following precaution when using the controller
with the mode switch set to MANU.
• After powering up the X-SEL, connecting the GOT
before the PC software causes the program startup
disabled (A1D alarm) on the X-SEL side.
