9.2.4.5 Control of three-position switch using RIO600 smart control module
When using RIO600 smart control module (SCM) for controlling a three-position
switch, the setting
Control mode
should be set as "With RIO600 SCM".
SCM is available with RIO600 to be able to drive a three-position switch. The
motor of the three-position switch is directly driven by the RIO600 SCM. RIO600
sends the status information to the protection relay by GOOSE communication,
and the switch position is indicated on the HMI on the protection relay. When
a three-position switch operation is requested and enabled by the protection
relay, it generates commands via EXE_DCOPEN, EXE_DCCLOSE, EXE_ESOPEN or
EXE_ESCLOSE, which are transmitted to RIO600 over GOOSE communication.
Though the command handling is pre-checked by P3SXSWI, RIO600 SCM further
checks for command priority and if the requested command is allowed. The
commands are always checked on rising edge by the RIO600 SCM.
In RIO600 SCM control mode, the operation timeouts in P3SXSWI are not available
due to external motor handling by the SCM module. Status feedback from the
module is returned to the protection relay via GOOSE. The inputs for P3SXSWI
shown in
Figure 833
must be connected by GOOSE status signals from SCM. Input
REED remains unconnected in this control mode.

Figure 833: Connections in P3SXSWI when using RIO600 SCM for a threeposition
switch
See the RIO600 and SCM manual when using RIO600 SCM for
threeposition switch motor control. All the signals from RIO600 must be
connected to the P3SXSWI function block as in
Figure 833
.
9.2.4.6 Control of three-position switch using H-bridge with static outputs
of the protection relay
When using the protection relay for direct motor control of the three-position
switch, the setting
Control mode
must be set as "Direct control".
If the protection relay is equipped with static power outputs, the three-position
switch's driving motor can be controlled with an H-bridge. The function has four
outputs for motor control.
