S7 protocol settings |
Home Back Next |
In Siemens S7 controllers and compatible the connection parameter details will be defined automatically.
If you have not set up the control online, the control type is not recognized.
If you are using a controller of the S7-1500 family, please select "s7 1500". The own TSAP is hex: 06 00 The remote TSAP is hex: 53 49 4D 41 54 49 43 2D 52 4F 4F 54 2D 45 53 As text: SIMATIC-ROOT-ES
In rare cases, with very old controllers and compatibles, the S7-200 protocol must be selected manually.
For the item access of S7 200 / 300 / 400 / 1200 please use the S7 item syntax.
If the controller is configured as a S7 1500 the variable access will work with symbol names directly. They can be found over online browsing. An item syntax does not exist in this case. Normally the elements are grouped in folders for the inputs, outputs, flags and the data blocks. If you do not like that uncheck the "Use folders in symbol browse".
The data blocks have numbers. This is true for the optimized data blocks also. Normally the data block numbers are not needed. If you need them please check "Show block numbers". Then the comments of the data blocks begin with the data block number.
Hint: In the S7 1500 data requested over networks are not synchronized with the PLC cycle. More information in the Siemens PLC manuals.
