The cable must be 15 m (49.21 feet) or shorter.
When the GOT is connected directly with the Q/QnA/A/FX/motion controller CPU, connecting a peripheral device such as a personal computer allows you to read, write and monitor the sequence programs of the CPU.
Sequence programs can be read/written.

*1 When using the transparent function, you cannot use the barcode function.
*2 When the PLC CPU is monitored by a peripheral device such as a personal computer, the display speed of the GOT decreases.

4.3.2 Instructions for using the transparent function
(1) Connect a peripheral device such as a personal computer to the RS-232C interface of the GOT.
(2) Only one of the bar code function, servo amplifier monitor function and transparent function can be used.
The following table indicates the priorities of the functions.
High Priority Low
Bar code function Servo amplifier monitor function Transparent function There is bar code setting in
the monitor screen data.
The extended function OS for servo amplifier monitor function has been installed in the GOT.
No setting items
The transparent function cannot be used when there is bar code setting in the monitor screen data or the extended function OS for servo amplifier monitor function has been installed in the GOT.
When there is bar code setting, delete the setting using GT Designer.
When the extended function OS for servo amplifier monitor function has been installed, delete the extended function OS.
(3) When connecting the GOT with the QCPU (A mode), refer to the QCPU (A mode) User's Manual for the GPP function software package and the startup-time type setting (PLC type).
(4) A communication error will occur if GT Designer of SW4D5C-GOTR-PACKE Version F or earlier is used to communicate with the GOT where the basic function OS and PLC communication driver of SW5D5C-GOTR-PACKE Version A or later have been installed.
If a communication error occurs, perform the same operation again. (A communication error occurs at the first time only.)
(5) The following cautions should be observed when using transparent function.
(a) Conditions transparent function will not work
The transparent function may not work if the following inoperable conditions are all met and further GX Developer is started with the RS-232C cable connected between the personal computer and GOT.
However, it will work if only one condition has not realized. (For example, it will work when the CPU to be monitored is QCPU.)
Item Conditions transparent function will not work Remarks CPU module to be
monitored ACPU Not applicable to QnACPU or
QCPU.
RS-232C cable AC30R2-9SS or AC30R2-9P of Version A or later is used.
Not applicable to AC30R2-9SS or AC30R2-9P of Version A or later.
(b) Countermeasures
Either of the following countermeasures allows transparent function to work normally.
1) Use an RS-232C cable of Version A or later.
2) For the cable whose Version is neither A nor later, reconnect it after disconnecting.
(c) How to verify the cable version
The RS-232C cables of Version A or later have the version number inscribed at the upper right of the model name marked on the connector.
AC30R2-9SS A
by GX Developer.
(a) The GOT monitor will stop.
(b) Operation by a touch switch or input by the numerical/ASCII input function cannot be performed.
(c) "315 Device write error" is displayed in the display field of the alarm list display (system alarm) function.
(d) Do not perform any operation that requires GOT restarting (downloading project data, changing utility or others) while setting a monitor condition.
If any operation above is performed, a system alarm of "402 Communication timeout." may be displayed on restarting the GOT.
In the case that a registered monitor condition for a PLC CPU cannot be canceled, reconnect the GX Developer to the PLC CPU to cancel the monitor condition setting. (An error may occur on canceling a monitor condition setting.)
(e) If the time check period of GX Developer is set to 30 seconds or longer in the monitor condition setting, "402 Communication time-out" is displayed in the display field of the alarm list display (system alarm) function.
In this case, change the time check period of GX Developer to shorter than 30 seconds.
(7) When executing PLC Write to a PLC CPU using the transparent function, the writing may be failed due to a cable disconnection or other reasons.
In the case above, retry PLC Write from the personal computer that has failed the PLC Write or reset the PLC CPU.
(8) If the following GOT functions are used when connecting with a QCPU (Q mode), an error may occur in a GOT or GX Developer.
The following lists the errors that may occur and their handling procedures.
GOT function Error message of GOT Handling on GOT side Error message of GX Developer
Handling on GX Developer side

(9) When the PLC CPU is monitored by a peripheral device such as a personal computer, the display speed of the GOT decreases.
(10) For 45 seconds after exit from GX Developer, the GOT remains at the same monitor speed as during use of the transparent function.
(11) The access range of GX Developer does not change when the transparent function is used.
(12) If the either of following operations, which will stop the monitoring of the GOT, is performed, the transparent function will stop.
(a) Monitor screen data is downloaded or uploaded using GT Designer, or OS or ROM_BIOS is installed. *1
(b) Setup or screen & OS copy is executed on the GOT unit. *1
(c) When no communication request (online monitor, etc.) has been issued from GX Developer for 45 seconds.
*1 A time-out error will occur on GX Developer.
When the option function such as the utility or ladder monitor function is executed, the transparent function will not stop.
(13) When using multiple software run on a personal computer, the communication using the transparent function is enabled for one software only.
Do not perform multiple communications using the transparent function at the same time. (The offline operation is enabled for each software.)
In addition, do not perform communication from the GT Designer to the GOT (downloading project data, etc.) during communication using the transparent function.
(14) When connecting to the FXCPU, set the transmission speed of the GX Developer to 9600bps.
Otherwise, the transparent function will not operate.
Use any of the following types of RS-232C cables for connection of the personal computer and GOT.
• AC30R2-9SS
• FX-232CAB-1
• AC30R2-9P *1
• F2-232CAB-1 *1
*1 9-25 pin converter (introduced product: D232J31 of Diatrend make) is required.
The RS-232C cable for connection of the personal computer and GOT may also be fabricated by the user.
The connection diagrams and connectors for the RS-232C cables are indicated below.
