5.4.12When 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 GOT-A900 GOT800

(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.

5.4.13When 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

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
