In the screen "Adress details," specify the communication access points ("TSAPs")
to be used. You will find the TSAP of a connection in the S7-200 system in STEP 7
Micro/WIN 32 in the screen in which you configured the individual connections un-
der the entry "Local Properties." Enter the communication access point specified
there in the screen "Adress details" in the fields provided for the TSAP of the part-
ner. The communication access point assigned in your S7-300 or S7-400 system
for the connection is located in the same screen under the entry "Local" in the field
"TSAP." Take the value indicated there and enter it in the entry "Remote Proper-
ties" in the field "TSAP" with STEP 7 Micro/WIN 32 in the screen from which you
took the communication access point used there.
S7-300 system as client
If you want to use an S7-300 system as client (i.e., you have activated "Active con-
nection generation" in the screen " Properties - S7 connection "), you can't just use
STEP 7 Micro/WIN 32 and enter the TSAP specified in STEP 7 in the entry "Local"
as the connection access point for your S7-300 system. Instead you must first re-
shape this TSAP according to the following rules.
1st byte of the TSAP:
Is taken from STEP 7, screen "Adress details," entry "Local," field "TSAP" 2nd byte
of the TSAP:
Is derived from the rack and the slot of your Ethernet communications processor
on your S7-300 system. The first 3 bits contain the number of the rack in which
your Ethernet communications processor is installed on your S7-300 system. The
remaining 5 bits contain the slot of your Ethernet communications processor in
your S7-300 system.
You will find these two pieces of information in the STEP 7 program packet HW-
Config.
Example
Your S7-300 system contains a CP 343-1 in slot 4 of rack 0. When you configure a
connection with STEP 7, this is indicated as local TSAP value 10.02. With STEP 7
Micro/WIN 32 use TSAP 10.04 as the communication access point on the S7-300
system. 1st byte (10 in our example) is accepted. 2nd byte is derived from the rack
(0 in our example) and the slot (4 in our example).
Caution
The specifications of communication access points ("TSAPs") in STEP 7 and in
STEP 7 Micro/WIN 32 must be compatible with each other.
