How can you group together the address area of the ET 200S (pack addresses)?

  • Entry
  • Associated product(s)

Description
Digital electronic modules with an address area of 2 or 4 bits first take up 1 byte per slot when inserted into the configuration table.
These instructions describe how you can group the ET 200S address area together.

Instructions

  1. "Packing addresses" using configuration via the hardware catalog
    (integrated metaknowledge)
  2. "Packing addresses" using configuration with GSD/GSDML file
    (PROFIBUS DP/PROFINET IO)

1. "Pack addresses" using configuration in the Hardware Catalog (integrated metaknowledge)
If you configure your ET 200S in the hardware configuration using the hardware catalog, you can simply group together the address area of the digital electronic modules using the "Pack addresses" button.
STEP 7 checks the configuration for consistency.

  1. Select a connected area of modules for which the addresses are to be packed.
  2. Click the "Pack Addresses" button in the detail view of the configuration table.

  1. After "Pack Addresses" the address area of the digital electronic modules is grouped together.

2. "Pack addresses"  using configuration with GSD/GSDML file (PROFIBUS DP/PROFINET IO)
This simplified function is not available when using the GSD/GSDML file in your configuration software. Pack the addresses manually by selecting the relevant modules. You recognize modules that can be grouped together because they are duplicated. The only difference between the two modules is in the "*" in the designation.
 

No. Procedure
1 Select a module without the character "*" at the end of the designation from the hardware catalog of your configuration software.
This opens a new byte and you assign the start address for the module.

2 For the following slot, choose a module with the character "*" at the end of thedesignation.
This enables you to store this IO address in the previously opened byte until all bits are taken up.

3 If a byte is filled, configure the module again without the character "*" at the end of the designation.

3 2DI DC24V ST 6ES7131-4BB01-0AA0 E 1.0 ... E 1.1
4 2DI DC24V ST* 6ES7131-4BB01-0AA0 E 1.2 ... E 1.3
5 2DI DC24V ST* 6ES7131-4BB01-0AA0 E 1.4 ... E 1.5
6 2DI DC24V ST* 6ES7131-4BB01-0AA0 E 1.6 ... E 1.7
7 2DI DC24V ST 6ES7131-4BB01-0AA0 E 2.0 ... E2.1
Table 02

Note

  • The correct grouping together of the modules is not checked by the configuration software. If you configure more than 8 channels into a byte, then the modules that exceed the byte limit are reported as wrongly configured in the diagnosis:
    Module status => 10B: wrong module; invalid user data
    These modules are not addressed.
    The total can be a maximum of 8 channels (1 byte).
  • The procedure described in this entry for summarizing the ET 200S address area is not permissible when using the PCS 7 channel driver blocks.
  • The ET 200S HS does not support the "Pack Addresses" function.
  • The central rack of the ET 200S CPU does not support the "Pack Addresses" function.
