W1CSWI1 OpCls.general CC1 Breaker1 close control
W1CSWI1 OpOpn.general OC1 Breaker1 open control
W1CSWI1 Pos.stVal 52A1?1:2
b
Breaker1 position
(52A = false, breaker opened; 52A = true, breaker closed)
W1XCBR1 BlkCls.stVal 0 Breaker close blocking not configured by default
W1XCBR1 BlkOpn.stVal 0 Breaker open blocking not configured by default
W1XCBR1 CBOpCap.stVal None Breaker physical operation capabilities not known to relay
W1XCBR1 Loc.stVal 0 Breaker local control status not configured by default
W1XCBR1 OpCnt.stVal 0 Breaker operation counts not available
W1XCBR1 Pos.stVal 52A1?1:2
b
Breaker1 position
(52A = false, breaker opened; 52A = true, breaker closed)
W2CSWI2 OpCls.general CC2 Breaker2 close control
W2CSWI2 OpOpn.general OC2 Breaker2 open control
W2CSWI2 Pos.stVal 52A2?1:2
b
Breaker2 position
(52A = false, breaker opened; 52A = true, breaker closed)
W2XCBR2 BlkCls.stVal 0 Breaker close blocking not configured by default
W2XCBR2 BlkOpn.stVal 0 Breaker open blocking not configured by default
W2XCBR2 CBOpCap.stVal None Breaker physical operation capabilities not known to relay
W2XCBR2 Loc.stVal 0 Breaker local control status not configured by default
W2XCBR2 OpCnt.stVal 0 Breaker operation counts not available
W2XCBR2 Pos.stVal 52A2?1:2
b
Breaker2 position
(52A = false, breaker opened; 52A = true, breaker closed)
a
Writing a 0 to WnCSWIn.CO.Pos.Oper.ctlVal (n = 1, 2) will cause OCn to assert and writing any other value will cause CCn to assert.
b
If breaker/contactor is closed, value = 10(2); if breaker/contactor is opened, value = 01(1).
