Communication via PROFIBUS
Cyclic communication
Note
S
The following must apply to ensure conformity with the PROFIdrive profile:
– Interconnect PZD receive word 1 as control word 1 (CTW1)
– Interconnect PZD send word 1 as status word 1 (STW1)
Use WORD format for PZD1.
S
One PZD = one word.
Only one of the interconnection parameters (p2051 or p2061) can have the
value 0 for a PZD word.
S
Physical word and doubleword values are inserted in the telegram as
referenced variables.
p200x apply as reference variables (telegram contents = 4000 hex or
4000 0000 hex in the case of double words if the input variable has the value
p200x).
