S7 - IE (TCP) / configured connection
This connection type allows to configure the connection to specified connection partners via Industrial Ethernet (TCP). The connection resource is reserved by the S7 PLC configuration which means it is definitely available.
IP address
The IP address (or host name) of the CPU. To use a specific port, the port number can be stated with the IP address, e.g. "192.168.1.13:120". The default port for the S7 driver is 102.

This check box defines the used PLC type. Following options are available:
-
S7-200 - communication with S7-200 devices
-
LOGO - communication with S7-LOGO devices
-
Other - communication with S7-300/400 devices

S7-LOGO | LOGO!Soft Comfort | TSAP (Server) | CPId corresponds to the number before the comma of the TSAP of the "Server" settings. E.g. TSAP = 02.00 -> CPId = 02 |
S7-300/400 | Step 7 NetPro | Connection resource (local) | CPId corresponds to the "Local" connection resource. |
PC-Rack
The PC rack number must be set as defined in the appropriate engineering tool. The table below shows which parameter of the respective engineering tool corresponds to the rack number.
PLC | Engineering tool | Parameter | Description |
---|---|---|---|
S7-200 | Step 7 Micro/WIN | TSAP (Remote Properties) | The rack number must be determined from the TSAP of the "Remote Properties". Refer to the example below for a detailed description. |
S7-LOGO | LOGO!Soft Comfort | TSAP (Client) | The rack number must be determined from the TSAP of the "Client" settings. Refer to the example below for a detailed description. |
S7-300/400 | Step 7 NetPro | Rack (Partner) | Use the "Partner" rack number. |
PC-Slot

How to Determine (PC-)Rack / (PC-)Slot for S7-200 and S7-LOGO devices
In case of S7-200 and S7-LOGO devices, CPId, Rack, Slot, PCId, PC-Rack and PC-Slot must be determined from the respective TSAP value.
-
TSAP (Local Properties / Server) = CPId, Rack, Slot
-
TSAP (Remote Properties / Client) = PCId, PC-Rack, PC-Slot
The number before the comma corresponds to CPId or PCId. The number after the comma must be converted from Hexadecimal to Decimal. Then you have to perform an Euclidean division by 32 to get the (PC-)Rack number. The remainder corresponds to the (PC-)Slot.
Example:
TSAP = 13.47
47 Hex -> 71 Dez
71 / 32 = 2 (with remainder 7)
PCId: 13
PC-Rack: 2
PC-Slot: 7
Configuration
S7-200
Configured connections for S7-200 devices are defined via the Ethernet Wizard of Step 7-Micro/WIN.
To apply the changes the S7-200 device must be restarted after the configuration.
If the checkbox "Accept all connection requests" is not set, you have to specify the IP address of the connection partner.
S7-LOGO
Configured connections for S7-LOGO devices are defined via LOGO!Soft Comfort.
