Ladder Symbol

When the execution condition is OFF, XFER(040) is not executed. When the ex-

ecution condition is ON, XFER(040) copies the contents of S, S+1, ..., S+N to D,

D+1, ..., D+N.

Both S and D may be in the same data area, but their respective block areas

must not overlap. S and S+N must be in the same data area, as must D and D+N.

N must be BCD.

1. For version-2 CVM1 CPUs, transfer source and destination words can over-

lap. This is not possible for other CPUs.

2. Refer to page 115 for general precautions on operand data areas.
