Internal Relays (R)

Function of internal relays (R)
This relay can be used only within program and on or off status does not provide an
external output. When the coil of the relay is energized, its contacts turn on.

Usage restrictions
When used as contacts, there are no restrictions on the number of times that can be
used.
As a rule, when specified as the output destination for operation results of OT and KP
instructions, use is limited to once in a program (to inhibit double output).
Note
You can permit duplicated use of an output by changing the
system register 20 setting. Even if the same relay is used as an
operand for instructions such as SET and RST, it is not regarded
as duplicated use of outputs.
For the FP2/FP2SH/FP10SH, if the Initialize/Test switch is set to the upper side (the
Initialize side) in the PROG mode, all of the internal relays (R) go off. If a hold type has
been specified (see next page), the internal relays (R) go off as well.
Note
With the FP2SH/FP10SH, system register 4 can be set in such a
way that the relays are not cleared even if the Initialize/Test
switch is set to the upper side.
