Execution time -
Operation Defines handling interval for drive-to-drive references 1 and 2, and the address (group
number) for standard (non-chained) multicast messages.
The values of the Ref1/2 Cycle Sel inputs correspond to the following intervals:
Note: Negative value of Ref2 Cycle Sel disables the handling of Ref2 (if disabled in the
master, it must be disabled in all follower drives as well).
Allowable values for the Std Mcast Group input are 0 (= multicasting not used) and
1…62 (multicast group).
An unconnected input, or an input in an error state, is interpreted as having the value 0.
The error codes indicated by the Error output are as follows:
See also section Examples of using standard function blocks in drive-to-drive
communication starting on page 439 .
Inputs Drive-to-drive reference 1 handling interval (Ref1 Cycle Sel): INT
Drive-to-drive reference 2 handling interval (Ref2 Cycle Sel): INT
Standard multicast address (Std Mcast Group): INT
Outputs Error output (Error): PB
