1.2 Explanation of Relays
Non−hold type relay and hold type relay
There are two types of internal relays: hold type relays and non−hold type relays. When
the power is turned off or the mode changed from RUN to PROG.,
− Hold type relays hold their on or off status and resume operation in that status
when the system is restarted.
− Non−hold type relays reset.
For the FP0 C10/C14/C16/C32, and FP−e without clock/calendar function, non−hold
type and hold type relay numbers are as follows:
Item Non-hold type Hold type
FP0 C10, C14, C16
FP−e
R0 to R60F (976 points) R610 to R62F (32 points)
FP0 C32 R0 to R54F (880 points) R550 to R62F (128 points)
For the FP0 T32C/FP0R/FPΣ/FP−X/FP2/FP2SH/FP10SH, and FP−e with clock/
calendar function, system register 7 can be used to specify whether a hold type or a
non−hold type is used. If the beginning of a hold type relay is specified using a word
number, relays before that point will be non−hold types, and subsequent relays will
be hold types.

FPΣ R0 to R89F (1440 points) R900 to R97F (128 points)
FP−e R0 to R60F (976 points) R610 to R62F (32 points)
FP−X/FP0R R0 to R247F (3968 points) R2480 to R255F (128 points)
Note
For FP0R, FPΣ, FP−X and FP−e, in case of not using back−up
battery, please keep the default value. Otherwise we cannot
guarantee the function of hold/non−hold value.
