Configuration
4.7 Process access
● Standard TSAPs
When the option is enabled, the device uses the standard TSAPs for its local TSAP and
the remote TSAP (S7 CPU). The standard settings for the remote TSAP are intended for
the case that you have not configured a connection to the gateway in the STEP 7 project.
TSAPs are entered as hexadecimal values. For an S7-300/400, the TSAP references the
rack, the slot and the type of CPU connection resource.
Examples for an S7-300 CPU:
– TSAP: 11.02
– TSAP: 03.02
The following standard TSAP IDs are used:
– Local TSAP of the gateway: 01.01
– Remote TSAP of the controller family:
Disable the option if the remote TSAPs do not match the preset standard TSAPs. In this
case, configure the TSAP that is assigned in the STEP 7 project.
● Local TSAP
Range of values: 01.01 ... 7E.7E
We recommend using the default TSAP (01.01).
● Remote TSAP
Enter the TSAP of the S7 connection assigned in STEP 7 at the station end if you have
configured a connection with an unspecified partner in the CPU for the gateway.
● Polling cycle (ms)
Cycle time in milliseconds in which the gateway reads the data from the station.
Range of values: 50...1 000 000 00
Note: If you transfer large volumes of data, the actual cycle time may be longer than
configured.
You configure the transmission speed and the other network parameters in the tab "Interface
configuration > PROFIBUS".
66
Rack 0, slot 2, connection resource 11
Rack 0, slot 2, connection resource 03
Connection configured at one end (Local end point "One-way") Connection partner
"unspecified"; the gateway as connection partner is not configured.
A connection resource for a connection configured at one end with unspecified partner
has the value 03.
A connection resource for a connection configured at both ends with unspecified
partner has the range of values 0x10...0xDF.
- S7-1200/1500: 01.01
- S7-300: 02.02
- S7-400: 03.03
