ABB 615 Series - L;R Control Access; Station Authority Level L,R

3.17.10.3 L/R control access
Four different Local/Remote control access scenarios are possible depending on the
selected station authority level: “L,R”, “L,R,L+R”, “L,S,R” and “L, S, S+R, L+S, L+S
+R”. If control commands need to be allowed from multiple levels, multilevel access can
be used. Multilevel access is possible only by using the station authority levels “L,R,L+R”
and “L, S, S+R, L+S, L+S+R”. Multilevel access status is available from IEC 61850 data
object CTRL.LLN0.MltLev.
Control access selection is made with R/L button or CONTROL function block and IEC
61850 data object CTRL.LLN0.LocSta. When writing CTRL.LLN0.LocSta IEC 61850
data object, IEC 61850 command originator category station must be used by the client,
and remote IEC 61850 control access must be allowed by the relay station authority.
CTRL.LLN0.LocSta data object value is retained in the nonvolatile memory. The present
control status can be monitored in the HMI or PCM600 via Monitoring/Control
command with the LR state parameter or from the IEC 61850 data object CTRL.LLN0.
LocKeyHMI.
IEC 61850 command originator category is always set by the IEC 61850 client. The relay
supports station and remote IEC 61850 command originator categories, depending on the
selected station authority level.
3.17.10.4 Station authority level “L,R”
Relay's default station authority level is “L,R”. In this scenario only local or remote
control access is allowed. Control access with IEC 61850 command originator category
station is interpreted as remote access. There is no multilevel access.

Figure 93: Station authority is “L,R”
When station authority level “L,R” is used, control access can be selected using R/L
button or CONTROL function block. IEC 61850 data object CTRL.LLN0.LocSta and
CONTROL function block inputs CTRL_STA and CTRL_ALL are not applicable for this
station authority level.
