Finally, in the "Address details" mask, define the communication end points
("TSAPs") to be used. The TSAP of a connection in the S7-200 system is found in
the STEP 7 Micro/WIN 32 in the mask in which you configured the individual con-
nections, under the "Local properties" entry. Enter the communication end point
specified there in the fields provided for the partner's TSAP in the "Address details"
mask. The communication end point assigned for the connection in your S7-300 or
S7-400 system is found in the same mask under the "Local" entry in the "TSAP"
field. Enter the value specified there in STEP 7 Micro/WIN 32 in the mask from
which you retrieved the communication end point used there. The value needs to
be entered in the "Remote properties" entry in the "TSAP" field in that mask.
S7-300 system as client
If you would like to operate an S7-300 system as a client, i.e. if you have enabled
the "Active connection generation" item in the "Properties - S7 connection" mask,
then you cannot directly use the TSAP specified in STEP 7 in the "Local" entry in
STEP 7 Micro/WIN 32 as a connection end point for your S7-300 system. You
must first transform this TSAP according to the following rules:
1st byte of TSAP:
Taken over from STEP 7, "Address details" mask, "Local" entry, "TSAP" field.
2nd byte of TSAP:
Derived from the rack and slot of your Ethernet communications processor in your
S7-300 system.
The number of the rack in which your Ethernet communications processor is in-
serted in your S7-300 system is specified in the first 3 bits.
The remaining 5 bits contain the slot of your Ethernet communications processor in
your S7-300 system.
These two values are found in the STEP 7 HWConfig program package.
Example:
A CP 343-1 is inserted in your S7-300 system in slot 4 in rack 0. When you config-
ure a connection with STEP 7, a value of 10.02 is displayed as the local TSAP. In
STEP 7 Micro/WIN 32, you must use a TSAP of 10.04 for the communication end
point in the S7-300 system (1st byte (here: 10) is taken over, 2nd byte is derived
from the rack (here 0) and the slot (here 4)).
Attention
The definitions for the communication end points ("TSAPs") in STEP7 and in
STEP 7 Micro/WIN 32 must be mutually compatible.
