OUTDA
Summary Sets FC 300 analog output.
Syntax OUTDA n v
Parameter n = output number (42)
v = value (0 – 100000)
NB!:
Parameter 6-50 must be set to “MCO controlled”.
Description With the OUTDA command it is possible to control the analog output of the FC 300
control card. FC 300 has one analog output. It is configured via parameter 6-50.
A FC 300 control card output can only be controlled from the application program
when it is configured as option output in the appropriate parameter.
Command Group I/O
Cross Index FC 300 Design Guide, parameter 6-50
Syntax Example /* condition: parameter 650 is set to "MCO controlled" */
OUTDA 42 50000 /* set FC 300 output to 10 mA */

PCD
Summary Pseudo array for direct access to the field bus data area
Syntax PCD[n]
Parameter n = index
Description You can directly access the field bus data area with the command PCD without an
additional command COMOPTGET or COMOPTSEND. The communications memory is
written or read word by word (16-Bit).
NB!:
The parameters 9-15 and 9-16 must additionally to be set with the correct values.
Command Group Communication option
Cross Index COMOPTGET, COMOPTSEND, SYSVAR
Syntax Example Variable = PCD[1] // Word 1
Variable = PCD[1].2 // Bit 2 of Word 1
Variable = PCD[2].b1 // Byte 1 of Word 2
PCD[1] = Variable
PCD[1].3 = Variable
Syntax Example _IF (PCD[2]= = 256) THEN // compare value
_IF (PCD[3].2) THEN // is bit 2 of PCD3 high?
