– Specify that the data placed in the receive buffer p8872 of node 2 in locations 0 to 4
will be received by node 1:
p8872[0] = 1
p8872[1] = 1
p8872[2] = 1
p8872[3] = 1
p8872[4] = 1
– Specify that PZD1, PZD2, and PZD3 of node 1 will be placed in the receive buffer
p8870 of node 2 in locations 0 to 4:
p8870[0] = 1 (PZD1)
p8870[1] = 2 (PZD2 first part)
p8870[2] = 3 (PZD2 second part)
p8870[3] = 4 (PZD3 first part)
p8870[4] = 5 (PZD3 second part)
– r2050 [0], r2060 [1] and r2060[3] now contain the values of PZD 1, PZD 2 and PZD 3
of node 1.
– Specify the PZD that node 2 should send:
:p2051[0] = drive1:r0899 (PZD length is 1 word)
– Place this PZD in the send buffer (p8871) of node 2:
p8871[0] = 1
– Specify the data that should be placed in the receive buffer p8872 of node 1 in
location 0, received from node 2:
p8872[0] = 2
– Define that PZD1 of node 2 is saved in the receive buffer p8870 of node 1 in location
0:
p8870 [ 0] = 1
– r2050[0] now contains the value of PZD 1 of node 2.
