Function
(1) Turns the user timing clock (SM420 to SM424, SM430 to M434), designated by
the duration equivalent to the number of scans specified by n1, and OFF for the duration
equivalent to the number of scans specified by n2.
(2) Scan execution type programs use SM420 to SM424, and low speed execution type
programs use SM430 to SM434.
(3) The following will take place if both n1 and n2 have been set for 0:
(a) n1 0, n2 0
(b) n1 0, n2 0
(4) The data designated by n1, n2, and
instruction is executed, and the timing pulse is turned ON and OFF by END processing.
Operation Error
(1) In any of the following cases, an operation error occurs, the error flag (SM0) turns ON, and
an error code is stored into SD0.
• The device designated by
• The values of n1 and n2 are less than 0.
Command
