The following section describes the positioning devices.
It indicates the device refresh cycles for signals with the positioning direction
PCPU→SCPU and the device fetch cycles for those with the positioning direction
SCPU→PCPU.

(1) Internal relays for positioning control are not latched even inside the latch
range.
In this manual, in order to indicate that internal relays for positioning
control are not latched, the expression used in this text is "M1600 to
M1999".
(2) Internal relays for positioning control are monitored from peripheral
devices as shown below.
(a) When peripheral devices are started with GSV13P/GSV22P, positioning
control internal relays within a latch range are indicated by L1600 to
L1999.
