Communications Card Description ZB4-601-IF1, ZB4-609-IF1 4-16
Moeller 07/01 AWB-C2700-1347GB
NOTES
• Configure the communications processor used for the specified parameters and select the low priority for
the PLC.
• Do not program any jobs for your CP but simply use the standard function blocks (RECEIVE_ALL and
FETCH_ALL). The ZB4-601/609-IF1 cannot accept jobs that are initiated by the CP.
• For active data exchange with the CP the function blocks mentioned must be called up in the main
program of the PLC (OB1).
• Remember that this interface is not only for the R3964R protocol but also requires the DK512 (= RK512)
data interpreter.
Example:
The CPU944 can run the R3963R protocol on the second interface using the 6ES5-816-1BB21 module.
This only enables data transport, however, the interpreter would have to be implemented in the control
program of the PLC (not recommended).
Note: this CPU can also process the AS511 protocol on the second interface.
• PLC and CP must both be in Run status.
• If data blocks or data words are addressed that are not available in the PLC, this will cause errors in the
communication.
