Issue
Is it possible to perform a Cold Reset in a logic subroutine using a SoMachine V4.3 / EcoStruxure Machine Expert Logic controller?

Product Lines
Modicon M238, M258, M241, M251, M262, HMISCU
SoMachine v4.3, EcoStruxure Machine Expert

Environment
PLC Programming software in Windows

Resolution
The two steps required are:

1. Set/write PLC_W.q_wPLCControl := PLC_W_RESET_COLD
2. Write PLC_W.uiOpenPLCControl  := 6699

For example, the Structured Text (ST) code would look like this:

IF PLCColdReset=TRUE
THEN
PLC_W.q_wPLCControl:=4;
PLC_W.q_uiOpenPLCControl:=6699;
END_IF
