Description
DIS_PCON BOOL Transitions of W#16#12 -> W#16#13 and W#16#13 ->
W#16#12 of CON_ARR[i].STAT_CON since the last SFC call
set CON_ARR[i].DIS_PCON to 1. All other connection status
changes do not affect CON_ARR[i].DIS_PCON.
Node:
When MODE=B#16#01 and 02, the operating system bit
that corresponds with DIS_PCON is reset when
connection data are copied to the target area.
When MODE=B#16#03, the operating system bit that
corresponds with DIS_PCON remains unchanged.
RES0 BYTE Reserved (B#16#00)
RES1 BYTE Reserved (B#16#00)

(W#16#...)
Description
0000

out without error.
MODE=B#16#03: RET_VAL W#16#0001 is not possible:
7000 First call with REQ=0. The job specified in MODE cannot be processed. BUSY value is
0.
7001 First call with REQ=1. The job specified in MODE has been initialized. BUSY value is 1
7002 Intermediate call (REQ irrelevant). Job still running. BUSY value is 1.
8080 Illegal value in the MODE parameter .
8081 Illegal data type in the CON_ARR parameter .
8082 Length description in the CON_ARR parameter too small. SFC copies no data to the
