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
- 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" |
- 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" |
- 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".
- 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
- Turn the power supply for the DP/DP coupler off.
- Pull the bus connector plug out of the PROFIBUS DP interface.
- Pull out the power supply of the defective DP/DP coupler.
- Loosen the screws of the DP/DP coupler that secure the DP/DP coupler to the rail.
- Swing the DP/DP coupler off the rail.
Mounting the new DP/DP coupler
- Hang the new DP/DP coupler on the rail and swing it down.
- Screw the DP/DP coupler tight.
- 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) .
- Insert the bus connector plug in the PROFIBUS DP interface.
- Switch on the power supply for the DP/DP coupler.
