Cautions
■Performing indexing between the FOR and NEXT instructions
Pulses can be output between the FOR and NEXT instructions by use of the edge relay (V). However, pulse output using the
PLS/PLF/pulse (P) instruction is not allowed.
When edge relay is used
M0Z1 provides normal pulse output.

The ON/OFF data of X0Z1 is stored by the edge relay V0Z1.
For example, the ON/OFF data of X0 is stored by V0, and that of X1 by V1.
■Performing indexing with the CALL instruction
Pulses can be output with the CALL instruction by use of the edge relay (V). However, pulse output using the PLS/PLF/pulse
(P) instruction is not allowed.
When edge relay is used
M0Z1 provides normal pulse output.
