8. Define the receive data for node 2:
– Specify that the data placed in the receive buffer p8872 of node 2 in locations 0 to 4
– Specify that PZD1, PZD2, and PZD3 of node 1 will be placed in the receive buffer
– r2050[0], r2060[1] and r2060[3] subsequently contain (after step 13) the values of
9. Define the send data for node 2:
– Specify the PZD that node 2 should send:
– Place this PZD in the send buffer (p8871) of node 2:
10.Define the receive data for node 1:
– Specify the data that should be placed in the receive buffer p8872 of node 1 in
– Define that PZD1 of node 2 is saved in the receive buffer p8870 of node 1 in
– r2050[0] subsequently contains (after step 13) the value of PZD 1 of node 2.
11.At the two nodes carry-out a "Copy RAM to ROM" to backup the parameterization and the
data.
12.Set p8842 =1 to activate parameters p8870, p8871 and p8872.
