Setting for Replace a DP/DP Coupler Siemens

QUESTION:
How do I replace a DP/DP coupler with the order no. 6ES7 158-0AD00-0XA0 with a DP/DP coupler with the order no. 6ES7 158-0AD01-0XA0?

ANSWER:

Compatibility
The DP/DP coupler with the order number 6ES7 158-0AD01-0XA0 is compatible to the DP/DP coupler with the order number 6ES7 158-0AD00-0XA0:

• The diagnostic information for the sync and freeze mode for the coupler with the order number ...-0AD01-... has been improved in comparison to the DP/DP coupler with the order number ...-0AD00-... and correspondingly adapted to the PROFIBUS norm.
• The DP/DP coupler with the order number ...-0AD01-... can be used as a replacement for predecessor modules. The design is compatible.

Exchanging the DP/DP coupler
Follow this procedure to exchange the DP/DP coupler. The individual steps are described below.

• Transfer the switch settings
• Dismantle the old DP/DP coupler
• Mount the new DP/DP coupler

Transferring the switch settings

1. Note the PROFIBUS addresses (DIL switch 1 to 64) from the old DP/DP coupler and set the identical PROFIBUS addresses on the new DP/DP coupler. The following applies:

DP/DP coupler (...-0AD00-...)	= =	DP/DP coupler (...-0AD01-...)
DP1 (DIL switch 1 bis 64)	= =	DP1 (DIL switch 1 bis 64)
DP2 (DIL switch1 bis 64)	= =	DP2 (DIL switch 1 bis 64)
Setting "0"	= =	Setting "OFF"
Setting "1"	= =	Setting "ON"

2. Transfer the diagnostics settings from the old DP/DP coupler:

DP/DP coupler (...-0AD00-...)	= =	DP/DP coupler (...-0AD01-...)
DP1 (diagnostics)	= =	DP1 (DIA)
DP2 (diagnostics)	= =	DP2 (DIA)
Setting "0"	= =	Setting "OFF"
Setting "1"	= =	Setting "ON"

3. Set the DIL switch "PS" (Power Supply). Only the new DP/DP coupler has a "PS" DIL switch with following settings:
   • PS (DP1) to “ON”: L+/M (PS1) is connected to DC 24 V
   • PS (DP2) to “ON”: L+/M (PS2) is connected to DC 24 V

We recommend the following procedure for switching to the new DP/DP coupler:

• Connect the power supply for the DP/DP coupler to "PS (DP2)"
  (see section "Mounting the new DP/DP coupler", step 3).
• Set the PS DIL switch (DP1) to "OFF".
• Set the PS DIL switch (DP2) to "ON".
  

4. Set the DIL switch "ADDR". Only the new DP/DP coupler has a "ADDR" DIL switch with following settings:
   • ADDR to “ON”: The DP/DP coupler gets the PROFIBUS address from STEP 7.
   • ADDR to “OFF”: The DP/DP coupler gets the PROFIBUS address from the DIL switch.

We recommend the following procedure for switching to the new DP/DP coupler:

• Set the DIL switch on DP1 and DP2 to "OFF". This means that the PROFIBUS addresses will be read directly from the DIL switch.

Dismantling the old DP/DP coupler

1. Turn the power supply for the DP/DP coupler off.
2. Pull the bus connector plug out of the PROFIBUS DP interface.
3. Pull out the power supply of the defective DP/DP coupler.
4. Loosen the screws of the DP/DP coupler that secure the DP/DP coupler to the rail.
5. Swing the DP/DP coupler off the rail.

Mounting the new DP/DP coupler

1. Hang the new DP/DP coupler on the rail and swing it down.
2. Screw the DP/DP coupler tight.
3. Connect the power supply back to the DP/DP coupler. Make sure that you have made the correcting setting on the "PS" DIL switch (see section "Transferring the switch settings ", step 3) .
4. Insert the bus connector plug in the PROFIBUS DP interface.
5. Switch on the power supply for the DP/DP coupler.
