SECTION 1
Features and System Configuration
This section describes the general features, system configuration, and word allocation of the G730 Interface Units.
The CPU handles the Interface Units as I/O Units, thereby eliminating tedious
procedures. Using a G730 Interface Unit allows signa ls for remote I/O equipment, such as switches and lam ps, to b e ha ndl ed and co ntr olled by the G730
Remote Terminal.
The G730 Remote Termin al is a terminal block with added communications
functions. It is connected to remote I/O equipment and PC s. Connecti on to
the PC by a single pair of cables reduces wiring effort.
For more information about the G730 Remote Terminal, refer to the I/O T ermi-nal Series Catalog (X044).
CQM1-G7M21 MasterSwitch settings on the Master allow simultaneous connection of G730
Remote Terminals (Slaves) with up to 32 input points and 32 output points.
Up to two Expansion Maste rs c an be con nec te d to ea ch Mas ter ( one syst em)
to permit control of up to 128 points.
Multiple Masters can be used.
Connection of multiple Masters in separate systems permits control within the
range permitted for the CPU.
The number of inpu t points a nd ou tput poin ts can in depend ently be switche d
between 32 and 16.
The HOLD/HOLD OFF setting d etermines whether the si gnals into the CPU
are held (HOLD) or cleared (HOLD OFF) when a transmission error occurs.
CQM1-G7N@1 Expansion
Master
An Expansion Master is used if the Master alone does not allow connection of
sufficient points. The Exp ansion Ma sters are always connected in series with
the Master and up to two Expansion Mas ters can be c onnected to eac h Master.
Expansion Masters are available as Input Units (G7N11) and Output Units
(G7N01). Switch settings allow connection of G730 Remote Terminals
(Slaves) with up to 32 points.
The number of inpu t points a nd ou tput poin ts can in depend ently be switche d
between 32 and 16 for both Input Units and Output Units.

Number of I/O WordsThe number of I/O words for the G730 Interface Unit Master and E xpansion
Master can be switched b etween 1 word and 2 words usi ng the DIP switch.
The number of I/O words s et affects the word all ocations and num ber o f connected Slaves. Set the required number of words to suit the Slave I/O type,
number of points, and number of Units.
Unit Number of Expansion
Master
Up to two Expansion Masters can b e connec ted to each Ma ste r. Set a unique
Unit number for each Expansion Master us ing the DIP switch. Either Expansion Master can be set as Unit 2, but a Slave address for Unit 2 can only be
used for an 8-point or 16-point Slave. It cannot be used for a 4-point Slave.
If only one Expansion Master is used, set it as Unit 1.
Word AllocationWord addresses are allocated sequentially from left to right to all I/O and other
mounted units, starting from 001 for inputs (000 is the CPU internal input) and
from 100 for outputs, independent of the Master and E xpansion Master Unit
number.
In multiple systems (using multiple Masters), the word addresses are allocated to the inputs and outputs sequentially from the leftmost mounted uni t,
independent of the system number.
DIP SwitchSet the DIP switch before turning the CQM1H/CQM1 power on. The switch
settings are enabled when the CQM1H/CQM1 power is turned on.

nection of up to 28 Slaves (G730 Remote Terminals).
Use the DIP switch to set the Slave address for each Slave to a value from #0
to #27. Addresses #2 4 to #27 cannot be set for 4-point Slaves. The Master
and Expansion Masters recognize the controlled Slave by the Slave address.

Slave address is mistakenly set between #4 and #7, the Slave outputs the
same data as the n address. All Slave outputs corresponding to the Expansion Master are OFF (0).
4. The following bits are allocated as Master and Expansion Master addresses and cannot be used by the Slaves.
Input bits: always OFF
Output bits: can be used as work bits

In this example, the Master and output Ex pansion Master Unit 1 ar e set to 2

Handling Power OnSection 4-2
4-2Handling Power On
After the power is tur ned on, the Master takes several seconds to recognize
all the Slaves. To start operation immediately at power on, write a program for
CQM1H/CQM1 to read the Transmission Ready si gnal and to wait until the
Transmission Ready signal turns ON.
The Master Transmission Ready s ignal is conn ected to CP U internal input bit
00000 and is used as a vir tu al flag by the Output Read y flag in the wor k bits
(02000).

Note It takes 1 s max. for the Transmission Ready output to turn OFF after a trans-
mission error occurs during normal operation.
On a transmission error, the CPU input and Slave output is determined by the
HOLD function setting of each Unit.
4-3Transmission Delay Time
The transmission delay time aris es because th e G730 Interface Unit communications is cond ucted by polling from the Mas ter to the Expansion Maste rs
and Slaves.
The maximum transmissio n delay time (Tmax) is calcula ted using the following formula.
Calculation of
Transmission Delay Time
54
Maximum transmission delay time (Tmax):
Tmax = ((no. Slaves + no. Expansion Masters + 2) x 1. 2 x 2) + S lave I/O ON/
OFF delay time (ms)
This calculation does not i nclude the response times between the CQM1H/
CQM1 and units.
Transmission Delay TimeSection 4-3
Refer to the CQM1H Operation Manual ( W 363) or the CQM1 O peration Manual (W226) for details about the CQM1H/CQM1 and unit response times.
Refer to I/O Ter minal Series Catalog (X044) for details a bout the Slave I/O
ON/OFF delay times.
For the system shown in the word allocati on example on pa ge 5 3, the time
(Tmax) between the input type Slave input signal turning ON, being read by
the Slave, and then being read by CQM1H/CQM1 from the Ma ster is calculated as follows (assuming the Slave input ON delay time is 1.5 ms.).
Example calculation of transmission delay time:
The maximum transmission del ay time (Tmax) for a system comprising seven
Slaves and one Expansion M aster is Tmax = (7+1+2) x 1.2 x 2 + 1.5 = 25.5
ms.
