9. Connecting to QCPU (Q mode)
(1) Restrictions for total cable length to number of GOTs connected
There are the following restrictions when three or more GOTs are connected.
Number of GOTs
15m or less
15 to 20m or less 20 to 25m or less
: There are no restrictions.
: Use the same power supplies of a programmable controller and all GOTs and turn on
or off all the power supplies simultaneously.
(2) When using Q00JCPU
The bus extension connector box can be connected only to the extension base unit.
(The bus extension connector box cannot be mounted on the main base unit.)
(3) When using Q00J, Q00, Q01 or Q02UCPU
When the GOT is connected to the Q00JCPU with the bus connection, the number
of extension stages including the GOT must be two or less.
When the GOT is connected to the Q00CPU, Q01CPU or Q02UCPU with the bus
connection, the number of extension stages including the GOT must be four or less.
(4) When using QA1S6 B extension base unit
Though the GOT is physically connected behind all the extension base units, assign
the GOT to the stage right behind the Q
the extension stage number setting. Assign the QA1S6
a stage next to the GOT.
10. Connecting to QnA(S)CPU type or An(S)CPU type
(1) Connecting to QnA(S)CPU type or An(S)CPU type
A GOT can be connected to an extension connector on only one side of the main
base unit.(GOTs cannot be connected simultaneously to the extension connectors
(2) When using Q4A(R)CPU, Q3ACPU, A CPU or A4UCPU
At least one empty slot for an I/O module is required in a programmable controller
(3) When using A0J2HCPU
Assign the GOT to the I/O slots 0 to 3 of the first extension stage.
(4) When using CPUs other than CPUs of (2) and (3)
Even if the maximum number of stages are used with no empty I/O slots, when there
is a free space of 32 I/O points or more, a GOT can be connected with the
following communication interface setting.
Max. stage No.
A3 CPU/A4 CPU
11. Connecting multiple GOTs
(1) System including different GOT series
The GOT1000 series cannot be used with different GOT series in a system.
GOT main unit
Bus connection unit
Total cable length
25 to 37m or less
B extension base unit in
B extension base unit as
Communication interface setting
(2) Restrictions on number of GOTs connected
There are restrictions on the number of GOTs connected depending on the target
CPU and the number of intelligent function modules mounted.
QCPU (Q mode)/Motion controller CPU (Q series)
QCPU (A mode)
AnUCPU, AnACPU, A2US(H)CPU
AnNCPU, AnS(H)CPU, A1SJ(H)CPU
*1: The following shows the models of connectable intelligent function modules.
AD51(S3), AD51H(S), AD51FD(S3), AD57G(S3), AJ71C21(S1), AJ71C22(S1), AJ71C23,
AJ71C24(S3/S6/S8), AJ71UC24, AJ71E71(-S3), AJ71E71N-B2/B5/T/B5T, AJ71E71N3-T,
AJ61BT11 (only for the intelligent mode), A1SJ71C24(-R2/PRF/R4), A1SJ71UC24(-R2/PRF/R4),
A1SJ71E71-B2/B5(-S3), A1SJ71E71N-B2/B5/T/B5T, A1SJ71E71N3-T, A1SD51S,
A1SJ61BT11 (only for the intelligent mode)
*2: A1SD51S is the only intelligent function module that can be connected to a QCPU (Q mode).
12. When using programmable controller CPU in direct mode
When the I/O control mode of the programmable controller CPU is the direct
mode, and if the first 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 programmable controller CPUs whose I/O control mode can be selected
by a switch, set the I/O control mode to the refresh mode before use.
Examples of using input X of an empty I/O slot
When input X is assigned on the MELSECNET/10 network
When input X of an empty I/O slot is turned on or off by the computer
When input X of an empty I/O slot is turned on or off by the touch
switch function (Bit SET/RST/Alternate/Momentary) of a GOT
13. Connecting to redundant Q4ARCPU system
(1) Connecting to redundant Q4ARCPU system with bus connection
Connect a GOT to the last redundant extension base unit (A68RB) of the
redundant Q4ARCPU system.
For the redundant extension base units, use version B or later.
The version can be confirmed in the DATE field of the rating plate.
Precautions for redundant Q4ARCPU system configurations
The GOT does not operate normally in the following system
When the GOT is connected to the bus switching module (A6RAF) on
the redundant main base unit (A32RB/A33RB) with the bus connection
When the GOT is connected to the version A redundant extension
base unit (A68RB) with the bus connection
(2) Power-on order for GOT and redundant Q4ARCPU system
Turn on the GOT and Q4ARCPU redundant system in the following order.
1) Turn on the GOT.
2) After the monitor screen is displayed on the GOT, turn on the redundant
Q4ARCPU system.A timeout error is displayed on the system alarm. Reset
the alarm with the system information.
