First commissioning steps
CP 340 first commissioning steps
1-4 Getting Started, 04/2005, A5E00442606-01
Receiving
If you are sending data from your communication partner, these are received by CP340 in
DB20 as the case may be. The destination specifications are created in the FC12 with the
label "AO:" or "A1:".
PEW0: to do this, on your "Input SM323" switch the bits 0.1 (Enable FC11 and FC12), 0.7
(EN_R for P_RCV) and 1.2 (select the destination offset "2" in the DB20) to "ON". Then the
CP340 will receive data via the serial interface (LED "RxD" flashes).
Assignment of the output location (PAW4)
Bit 0.0: "Done" of a successful SEND
Bit 0.1: "Error" of a damaged SEND
Bit 0.2: "BIE" of a SEND
Bit 0.4: "NDR" of a successful RECV
Bit 0.5: "Error" of a damaged RECV
Bit 0.6: "BIE" of a RECV
Diagnostics functions
Errors can occur in the case of incorrect operation, incorrect wiring of the serial interface or
inconsistent configuration.
The manual describes how to diagnose such errors and messages.
