Manual VIPA System 300V Chapter 6 Deployment CPU 31x with TCP/IP
HB130E - CPU - Rev. 11/50 6-65
The frequency, with which a SEND job is issued, depends on the time that
was configured for the FC1 call. The timer in this example is configured for
1000ms. The sample program initiates the SEND job at a rate of once
every 1000ms.
Data Word DW 0 of the data Block DB 11 is incremented ahead of the
SEND call, that actually transmits a message. This occurs in function block
FC 1. All together 16bytes of data are transmitted. The partner station
receives the data and stores it in DB 12.
Together with DW 0, 15bytes of additional user data may be transferred.
The data blocks DB 11 and DB 12 have the same structure:
The data transmission takes place via MPI. If your programming device
(PG) has no MPI adapter, you may use the "Green Cable" from VIPA
(VIPA 950-0KB00) to establish a serial point-to-point connection between
the PC and the CPU.
The "Green Cable" may only be used with the VIPA CPUs of the Systems
100V, 200V and 300V.
• Connect your PG with the CPU.
• Via PLC > Download in your projecting tool you transfer the project into
the CPU.
• Plug in a MMC and transfer your user application to the MMC via PLC >
Copy RAM to ROM. During the write operation the "MMC"-LED on the
CPU is blinking. For internal reasons the message signaling completion
of the write operation arrives too soon. The write operation is only
completed, when the LED has been extinguished.
• Switch both CPUs into RUN.
