8.5 Error status register
The HR 60 and HR 61 error status registers (holding register - 16-bit) are used to indicate con-
troller or system errors. HR 60 contains general alarms, whereas special faults are entered in
HR 61. In modem mode (Co9 -> Fb01 = ON), the change in state of HR 60 or HR 61 causes the
controller to dial the control system.
In InF8 level the bits of the error status register are displayed:
4
FSR1 (general error):
The corresponding block at the top is set for every bit set
4
FSR2 (special error):
by pressing
key, the set bits are displayed similar to FSr1
In both cases, the blocks 20 to 23 are visible when a bit is set in another error status register
(which is currently not visible) to make it immediately recognizable whether one of the maxi-
mum 32 error flags has been set.
