6.4.2.3 Jobs to be performed by the PLCs
Jobs for PLC 1
• Every 100ms the data words DW0 to DW99 are transferred via the data module DB11.
• The data word DW0 of DB11 is used as a message counter. It is incremented only when the
previous send job has been completed correctly (complete without errors). The remaining data
words (DW1toDW99)maybeusedtotransferuserdata.
• SEND is configured by the job number A-NR = 11 and the base-frame number SSNR = 0 .
• Source parameters must be configured directly.
Jobs for PLC 2
• PLC2 must receive the data transmitted by PLC1 and deposit it in data module DB12. The
RECEIVE handler module must be used for this purpose.
• Handler module RECEIVE is configured by means of the job number A-NR = 12 and the base-
frame number SSNR = 0 .
• The destination parameters are saved in the data module DB12 from data word DW0.
• The entered base-frame number SSNR = 0 must correspond with the configuration of the
CP143 H1 / TCP/IP module. For this example this configuration is identical to the one shown for
the CP143 H1 / TCP/IP in PLC 1
This concludes the description of the problem and the required configuration settings. For further
details on the configuration of the handler modules you may refer to the programs in chapter 6.4.3.
Chapter 6.4.4 describes the respective configuration for the CP143plus under H1 and Chapter 6.4.5
CP143 TCP/IP under TCP/IP in detail.
