First Steps in Commissioning
Test
Double-clicking VAT1 in the "Blocks" directory in your project allows you to monitor the data
transfer:
● Select PLC > Connect to > Configured CPU to go online.
● Select Variable > Monitor to switch to monitoring mode.
You can view the number of transmissions at the operand "DB42.DBW0" (Send counter).
You can see if you have received data with the "DB41.DBW18" (Receive counter).
If you are using your programming device as a connection partner, you can receive data
from and send data to the CP 341 with the "Hyper Terminal" program. Double-clicking the
"Getting.ht" file (stored in \Siemens\STEP7\s7ftptp\Terminal\...) starts "HyperTerminal" with
the appropriate settings. The data sent by the CP 341 are displayed. The corresponding
characters are sent to the CP 341 by pressing a key on your keyboard.
Diagnostics
Errors can occur in the case of incorrect operation, incorrect wiring of the serial interface or
inconsistent parameter assignment. The manual describes how to diagnose such errors and
messages.
