*1 Use only modules with the upper five digits of the serial No. later than 12042.
*2 Use the serial port of a serial communication module controlled by another CPU on the multiple CPU.
*3 If the A series computer link module is applied to the QnACPU, the GOT can monitor the devices in the same range on AnACPU.
However, the following devices cannot be monitored.
• Devices added to QnACPU
• Latch relays (L) and step relays (S)
(In case of QnACPU, the latch relay (L) and step relay (S) are different from the internal relay. However, whichever is specified,
an access is made to the internal relay.)
• File register (R)
