30.4 Precautions
1 GOT's communication timing
(1) GOT's communication timing
Adjust the communication timing so that, after applying the power to the system, the
communication with the connected device (MITSUBISHI PLC) is performed in order starting from
the first GOT (from the 1st GOT to the 2nd, and so on).
When the communication is failed, retries are performed. And if the predetermined time has
elapsed, a communication error occurs.
(2) Adjusting communication timing
(a) When powering up the system simultaneously
Using the utility or selecting [GOT Setup] - [Opening Screen Time] from GT Designer2, set the
opening screen time adding a delay to each setting for the GOTs. During the opening process,
communication with the connected device does not start.
Example: Set value of "Opening Screen Time" (Inside (): set value)
(b) When powering on devices individually
Turn on the connected device first, and then the first GOT, the second GOT, and so on.
*1 If the first GOT is turned on after a while the second GOT is turned on, because the communication
start of the second GOT is delayed, a communication error may be detected at the second GOT.
*2 If the system power is turned on simultaneously and it takes time to start the communication of the
second GOT, a communication error may be developed.
