Description:
The converter requires a power supply of +5 V on PIN 14, which is supplied by the controller interface.
This power supply is ensured with the following devices: 

• AG90U/95U/100U/101U/115U/115H/
• AG135U/155U  (CPU921, 920, 922, 928A, 928B, 923, 947, 947R, 948)
• CP530
• IP252 (only AG115)
• IP262

The pin assignment for the PC converter (MLFB 6ES5 734-1BD20) is displayed in the following figure:

Note:
Another cause might be that the device is equipped with a low-power interface. These interfaces provide much smaller voltages and currents on the send lines than normal RS232 interfaces. These interfaces are used on the RS232 side in many laptops/desktops and also in some USB adapters. For more information please refer to the manufacturer concerned.

QUESTION:
Why are no characters transmitted by my keyboard to the Power PG?

ANSWER:
There can be different causes, if no input (or mouse movements) are transmitted by the keyboard to the Power PG.

1. The status LED does not display anything:

   The Power PG is out of the reach of the keyboard and cannot receive any infrared signals.

   Remedy:
   Reduce the distance between Power PG and keyboard or align the keyboard with the Power PG more efficiently.

2. The status LED flashes red while keyboard input:

   You have changed the keyboard ID of the keyboard unintentionally during character input over the keyboard. This might occur by using the keys "Fn"+"Alt"+, "ID" simultaneously (whereby "ID" corresponds to a number of the numeric block).
   Or you have used the keyboard of an adjacent Power PG which has a different ID qualifier.

   Remedy:
   Mark the areas provided with the ID qualifier at the Power PG and at the keyboard to avoid a confusion of keyboard and equipment.

   The keyboard ID can be set correctly again without wrong inputs into the Power PG or the adjacent Power PG.
   If the ID set in the set-up is known, the right connection simply can be set again with the key combination "Fn"+"Alt"+, "ID", (ID qualifier). The "ID" has to be entered with a number of the numeric block and not with the numbers from the alphanumeric block. For the confirmation of the right ID, the status LED in the right upper screen area flashes.

   Shoud the ID be unknown, the connection simply can be established again by trying out the possible ID of 0 to 9. The key combination "Fn"+"Alt"+, "ID", has to be hit simultaneously, whereby "ID" corresponds to a number of the numeric block. Between the tries, all keys must be let go. The right ID is indicated in the right upper screen area by flashing of the status LED.

3. The status LED is permanently red:
   

   The cause for this state is that the charge of the batteries of your keyboard is low or none at all.

   Remedy:
   You can immediately continue to work with the USB cable provided along with the PG. Connect the USB cable to the keyboard and to a free USB port of the PG. The USB cable provides the keyboard with tension.
   Exchange the batteries on the next occasion. 4 Alkaline batteries of the type "Mignon (AA)" are needed.

   Note:
   The USB cable is only for power supply! Data is still transmitted over the infrared interface.
   The USB cable is not for charging the batteries or the accumulator.

Note about the connection of an external mouse:
If you would like to connect an external mouse to the Power PG, the touchpad of the keyboard is still active. You can deactivate the touchpad in the set-up by clicking on "Menu Main > Hardware Options > Touchpad" setting "Disabled" there.

There is also the possibility of deactivating the touchpad during operation. To do so, use the key combination "Fn" + "~". With the help of this key combination, the touchpad also can be reactivated. Please take into account that the touchpad needs about 5 seconds for initialization. You should not execute any touchpad operations during initialization.

QUESTION:
Why does my USB keyboard not work with the Power-/ or Field-PG?

ANSWER:
A standard keyboard has been connected to the Field or Power-PG. After a while the PG starts showing different abnormal behavior and becomes impossible to operate. In the USB V1.1 specification, a voltage range of 4.75V up to 5.25V is specified, which corresponds to the rectified voltage of 5V ±5%.

Some manufacturers of keyboards and mices do not keep up with this range. During the examination of one of these keyboards, it appears that difficulties occure after about 60 to 90 seconds starting at a tension of 5.09V. With increasing tension the behavior deteriorates.

The programming devices of Siemens provide a regulated tension of 5.14V and fulfill the general EMV requirements for the industry.

Remedy:
The problem can be solved as follows:

• Use of a HUB, which is inserted between the keyboard and the PG.
• Use of the unblocked, industry fit USB keyboard which complies with the general EMV requirements.
  (e. g. IPC-catalog: Microsoft Office Keyboard model RT9450)
  

Description:
You can connect the PG 6xx and PG 7xx with different modules. All the information you need for this is available in this FAQ:

• How do you connect the PG 675/685 and the PG7xx programming devices
  to the PLCs S5 150A/K/U/S, S5 130WB and S5 110S?
• What should you pay attention to when making a cable connection from PG
  6xx to AS 511 - interface module (AG 130 / AG 150)?
• What connection cable do you need between the PG 6xx and
  the programmable controllers AG 90 U to AG 155 U?
• How should the interfaces of a CP525 and a
  PG 6xx/7xx be connected with each other?

How do you connect the PG 675/685 and the PG7xx programming devices to the PLCs S5 150A/K/U/S, S5 130WB and S5 110S?

Description:
There are no problems when setting up connections from the PG 675/685 and the PG 7xx programming devices to the PLCs S5 150A/K/U/S, S5 130WB and S5 110S?
Since the PLCs have an interface module AS 511 (25-pin), it is possible to connect the PGs. You must just pay attention to the following.

• You only need plug-in connecting cable 6ES5 731-0xxx0 for PGs 675 and 685.
• If you want to connect a PG 7xx, you need the adapter 6ES5 731-6AG00 in addition to the plug-in connecting cable 6ES5 731-0xxx0. There is no direct cable available for the PGs 7xx, but it can be made following the attached cable assignment diagram.

What should you pay attention to when making a cable connection from PG 6xx to AS 511 - interface module (AG 130 / AG 150)?

To make the connection cable, you need a 25-pin Sub-D plug on the PG side and a 25-pin Sub-D socket on the side of the AS 511 interface module. The attached file "d_6xx511.pdf" shows the wiring.
