A.1.4 CS4 - AUTOMATIC/MANUAL STATION
The automatic/manual station configures the controller into a conventional single station automat-
ic/manual selector with manual loading.
Loading CS4 initializes the CON0 display mode to 4. The Auto/Manual Station is shown in block
diagram form in Figure A–4. Also provided is Table A-4, which is a worksheet that shows the CS4
wirelist connections; wirelist datapoints not connected are left at default. Table A-4 is partitioned
by FCS module type applicable to CS4 (those modules illustrated in Figure 2-1). The datapoint pa-
rameters for each module are shown with their default values.
The following I/O assignments result from loading CS4:
ANI0 Auto Input
ANI2 Alarmed Variable
ANI3 Tracking Input
ANO0 Station Output
CCI0 Force Output Tracking
CCI1 Auto Enable
CCO0 Process Alarm 1
CCO1 Process Alarm 2
The unit operates as a standard auto/manual selector and manual loader. Transfer from automatic
to manual is bumpless, after which the output may be manipulated via the output push buttons. In
automatic, the signal on ANI0 is passed through to the station’s output. Automatic selection can
be overridden by an open contact at CCI1. The station’s output tracks ANI3 when an open contact
appears on CCI0 and output tracking is enabled (L119 = 1). The station also provides alarming,
based on an independent signal (ANI2). Alarm conditions are reflected by CCO0 and CCO1.
