60016	i_lwSystemFault_1	LWORD	Bit field `FFFF FFFF FFFF FFFF` hex indicates no error detected. A bit at low level (0) means that an error has been detected: bit 0 = Expert I/O error detected bit 1 = I/O bus error detected bit 2 = Ethernet IF1 error detected bit 3 = Ethernet IF2 error detected bit 4 = Serial 1 in overcurrent error detected bit 5 = Serial 2 in overcurrent error detected bit 6 = CAN 1 error detected bit 7 = Reserved bit 8 = Reserved bit 9 = Communication bus error detected bit 10 = SD Card error detected bit 11 = Firewall error detected bit 12 = DHCPS/FDR server error detected bit 13 = OPC UA server error detected bit 14 = Communication bus error detected bit 15 = Communication bus health error detected bit 16 = Ethernet IF2 Ring root error detected bit 17 = Encoder power supply error detected bit 18 = Encoder communication error detected bit 19 = TMSES4 IF1 configuration error detected bit 20 = TMSES4 IF2 configuration error detected bit 21 = TMSES4 IF3 configuration error detected bit 22 = Server address error detected bit 23 = NTP error detected bit 24 = Syslog error detected
60020	i_lwSystemFault_2	LWORD	Bit field `FFFF` hex indicates no error detected. If i_wIOStatus1 = PLC_R_IO_SHORTCUT_FAULT, the meaning of i_lwSystemFault_2 is: bit 0 = 0: short-circuit detected in output group 0 (Q0...Q1) bit 1 = 0: short-circuit detected in output group 1 (Q2...Q3) bit 2 = 0: short-circuit detected in output group 2 (Q4...Q7) bit 3 = 0: short-circuit detected in output group 3 (Q8...Q11) bit 4 = 0: short-circuit detected in output group 4 (Q12...Q15)
60024	i_wIOStatus1	PLC_R_IO_STATUS	Embedded Expert I/O status.
60025	i_wIOStatus2	PLC_R_IO_STATUS	TM3 I/O status.
60026	i_wClockBatterystatus	WORD	Status of the battery of the RTC: 100 = Battery fully charged Not applicable for M262 Logic/Motion Controller.
60028	i_dwAppliSignature1	DWORD	First DWORD of 4 DWORD signature (16 bytes total). The application signature is generated by the software during build.
60030	i_dwAppliSignature2	DWORD	Second DWORD of 4 DWORD signature (16 bytes total). The application signature is generated by the software during build.
60032	i_dwAppliSignature3	DWORD	Third DWORD of 4 DWORD signature (16 bytes total). The application signature is generated by the software during build.
60034	i_dwAppliSignature4	DWORD	Fourth DWORD of 4 DWORD signature (16 bytes total). The application signature is generated by the software during build.
n/a	i_sVendorName	STRING(31)	Name of the vendor: “Schneider Electric”.

n/a	i_dwLastPowerOffDate	DWORD	The date and time of the last detected power off in seconds beginning with January 1, 1970 at 00:00 UTC. NOTE: Convert this value into date and time by using the function SysTimeRtcConvertUtcToDate. For more information about Time and Date conversion, refer to the Systime Library Guide.
n/a	i_uiEventsCounter	UINT	Number of external events detected on inputs configured for external event detection since the last cold start. Reset by a Cold Start or by the PLC_W.q_wResetCounterEvent command.

n/a	i_udiUsrFsFreeBytes	UDINT	User FileSystem free memory size (in bytes).
n/a	i_uiTM3BusState	PLC_R_TM3_BUS_STATE	TM3 bus state. i_uiTM3BusState can have the following values: 1: TM3_CONF_ERROR Configuration mismatch between physical configuration and EcoStruxure Machine Expert configuration. 3: TM3_OK Physical configuration matches EcoStruxure Machine Expert configuration. 4: TM3_POWER_SUPPLY_ERROR TM3 bus is not powered (for example when the controller is powered by USB).
n/a	i_ExpertIO_RunStop_Input	BYTE	Run/Stop input location is: 16...FF hex if the expert I/O is not configured 0 for `%IX0.0` 1 for `%IX0.1` 2 for `%IX0.2` ...and so on.
n/a	i_x10msClk	BOOL	TimeBase bit of 10 ms. This variable is toggling On/Off with period = 10 ms. The value toggles when the controller is in STOPPED and in RUN state.
n/a	i_x100msClk	BOOL	TimeBase bit of 100 ms. This variable is toggling On/Off with period = 100 ms. The value toggles when the controller is in STOPPED and in RUN state.
n/a	i_x1sClk	BOOL	TimeBase bit of 1 s. This variable is toggling On/Off with period = 1 s. The value toggles when the controller is in STOPPED and in RUN state.
(1) Not accessible through the application as %MW. n/a means there is no pre-defined Modbus address mapping for this system variable.
