When Connecting Multiple Gots; When Using A Plc Cpu In The Direct Mode - Mitsubishi Electric GT1685 Connection Manual

5.4.12 When connecting multiple
GOTs
(1) System including different GOT series
The GOT1000 series can be connected with GOT-A900
series in a system.
When using them together, refer to the following
Technical News.
Precautions when Replacing GOT-A900 Series
with GOT1000 Series (GOT-A-0009)
The GOT1000 series cannot be used with GOTs other
than GOT-A900 series in a system.
GOT1000
(2) Restrictions on No. of GOTs
The number of connectable GOTs is restricted
according to the CPU type and the number of intelligent
function modules.

5.4.13 When using a PLC CPU in the
direct mode
Note that when the I/O control mode of the PLC CPU is the
direct mode, and if the 1st GOT is connected to the main or
extension base unit with a 5m extension cable (GT15-
AC50B, GT15-A1SC50NB), the input X of the empty I/O
slot cannot be used.
No restrictions apply when the I/O control mode is the
refresh mode.
On PLC CPUs whose I/O control mode can be selected by
a switch, set the I/O control mode to the refresh mode
before use.
POINT POINT POINT
In the cases where input X of an empty I/O slot is used
(1) When input X is assigned on the MELSECNET/10
network
(2) When input X of an empty I/O slot is turned ON/
OFF by the computer link module
(3) When input X of the I/O slot is turned ON/OFF by
the touch switch function (Bit SET/RST/Alternate/
Momentary) of GOT
