Startup Characteristics of the CP 440 Programmable Logic Controller
The configuration data is created with the aid of the CP 440: Point-to-Point Communication,
Parameter Assignment parameter assignment and transferred to the CPU with the STEP 7
software. Each time the CPU is started up, the current parameters are transferred to the
CP 440 by the system service of the CPU.
Startup Characteristics, FB-CP 440
Once the connection between the CPU and the CP 440 has been established, the CP 440
must be initialized.
For each function block (SEND_440, RCV_440, RES_RECV) there is a separate startup
coordination. Before requests can be actively processed, the accompanying startup
procedure must be completed.
Disabling alarms
In the function blocks the interrupts are not disabled.
Addressing the Module
The logical basic address is defined via STEP 7 and must be specified by the user under the
block parameter LADDR.
