QUESTION:
Why don't the analog modules transfer the parameterization data
(e.g. measuring range, limit values, ...) although the ET 200S, ET
200M or ET 200X slave is running under an external master without
any error messages?
ANSWER:
When using different systems there might be differences in the slot
counting. Some configuration systems for external masters start
slot counting on the module with the address 0 or 1. On the remote
modules ET 200S, ET 200M and ET 200X slot counting starts with slot
4.
If the error described above occurs, then please check the
parameterization message with regard to the specification of slots
in the parameter record belonging to the module.
A parameter record for a module in the ET 200M is structured as
follows, for example:
|
|
Byte 0:
|
40
|
...
|
|
|
Byte 1:
|
00
|
...
|
|
|
Byte 2:
|
00
|
...
|
|
|
Byte 3:
|
15
|
Block length
|
|
|
Byte 4:
|
5F
|
S7 constants
|
|
|
Byte 5:
|
04
|
Slot number of the module
|
|
|
Byte 6:
|
00
|
Data record number
|
|
|
etc.
|
|
|
Make sure that the slot numbers of the individual modules are
specified correctly. The first module in the ET 200 modules has
slot number 4. The slot numbers of all the other modules are to be
adapted accordingly.
Note:
A description of the configuration and parameterization messages
for the relevant ET 200M and ET 200X modules is given in the
following two Entry IDs: 1455647, 2836173.
