The following system configurations and connection conditions assume bus connection with the QCPU (Q mode). The numbers ( to ) given in the system configurations denote the numbers ( to ) in "(2) System equipment". Refer to these numbers when you want to confirm the types and applications.
POINT
• Up to five GOTs may be connected.
• Select the connection cables whose lengths satisfy the conditions of the maximum distance depending on the connection conditions.
• Installing the first connected GOT more than 13.2m away requires the bus extension connector box . When the Q00JCPU is used, however, the bus extension connector box 3 cannot be used and the GOT should therefore be installed within 13.2m.
