Precautions

■1. 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.
■2. 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.
■3. 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.
■4. Device reserved for system use
Devices of "Reserved for system use" are devices with indefinite values. Do not write to these devices.
■5. 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.
■6. 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.
■7. Station number setting of the IAI robot controller system
The robot controller with the station number set with the host address must be included.
