4.5 Special features for the configuration of transparent connection
modules
Take these special features into account when you configure transparent SI-
MATIC connection modules (6DS1310, 6DS1321 and 6DS1327):
• Modules 6DS1321-8AA and 6DS1327-8AA programmed directly with
this MLFB use respectively 8 or 16 successive module numbers (MNO).
Here you must configure a start MNO = n x 8 or n x 16 (or for the I/O bus
these numbers + 100). The counting method in the manuals is here “n” =
0, 1, 2, ... 7 or 15 = module number of the connection groups.
• Further TELEPERM modules entries in this used area of 8 or 16 module
numbers are permitted. However, they do not have any effect, that is,
these modules will not be addressed.
• When you configure BGNR = 32 for a connection module, for example,
enter a byte address Nrxxxx.Kanal = 3 x 64 = 192 to reach the start of
BGNR = 35, and with = 194 you reach a module with the byte address
channel = 2 within BGNR = 35.
Caution: ”Nrxxxx.Kanal” is always a byte address (applies to analog mo-
dules as well).
• Not allowed are start BGNR 56 and 156 for 6DS1321-8AA and 48 und
148 for 6DS1327-8AA, because otherwise the prohibited areas (BGNR =
61 ff or 161 ff) would be covered. In this case you must use the substitute
configuration to configure the required MNOs explicitly, that is, for every
MNO used by the connection module you must configure one separate
6DS1310-8AA.
• A granular MON mix of TELEPERM and SIMATIC modules with
6DS1327-8AA also requires a substitute configuration.
Such overlaps are currently not possible with 6DS1321-8AA, they must
be cleared.
• With 6DS1321-8AA, coding switch 6 must be set to OFF (EANK active),
otherwise the process control message S 313 is output.
• Special care must be exercised when entering data, since the configura-
tion tool does not safely prevent an overlap of process images with the
modules mentioned above, or only shows the assignment without output
of an explicit error message; for example, the author must take the limita-
tion of channels (maximum = 63) into account when he creates his confi-
guration with 6DS1310.
– With confguration errors, e.g. if a driver block accesses a subordinate
I/O module which has not been configured and is therefore not exi-
sting because of a wrong configured channel number, possibly no ack-
nowledgement error S305 will be signaled.
– In principle the corresponding module width has to be configured for
each S5 module with S5_Typ as far as possible. Especially combining
several modules has to be avoided.
Example: 2 byte binary input S5_Typ = DE2;
4 byte binary output S5_Typ = DA4;
