Procedure for groupable modules
In the hardware catalog of your configuration software, you can recognize groupable
modules by the fact that they are available in duplicate. The modules differ from each other
only by a " * " in the designation. To group modules, follow the steps below:
1.
Configure the ET 200S setup, adhering to the following rules:
–
The modules that you can group in a single byte must be of the same module type
(see section above).
–
There can be a total of no more than 8 channels (1 byte).
2.
Select from the hardware catalog of your configuration software the module designation
without " * ".
–
Result: You open a byte and store the first module there.
3.
Select from the hardware catalog of your configuration software the module designation
with " * ".
–
Result: In the open byte, you store additional modules until all the bits are occupied.
4.
If a byte is filled, you must configure a module again (that is, open a new byte without
" * ").
Note
The configuration software does not check whether the modules have been grouped
correctly. If you configure more than 8 channels in one byte, the modules that exceed the
byte limit are reported as being incorrectly configured in the diagnosis:
Module status
→
10
B
: Incorrect module; invalid user data
These modules are not addressed.
Note
The EIP-200S Ethernet/IP Adapter assembles data on byte boundaries. Some scanners may
only provide access to this data on word boundaries. You should organize your ET 200S
modules to conform to the scanner's restrictions. For example, configure the grouping of
digital modules so that an analog module will occupy bytes 0 to 3 or 4 to 7. In this way, the
analog modules will begin on even-byte boundaries to avoid an analog value being split
between two words.
