Parameters of the Processor Module

In the device tree, double-click the Processor Module node. In the editor window open the PMxxx Parameters tab and check whether the default configuration is to be changed.

The following parameters are available:

Parameter Default Value Meaning

Auto run

Parameters of the Processor Module

On On If the Flash memory contains a valid project, the project will be loaded into the RAM memory and executed when switching on the CPU.
Off If the Flash memory contains a valid project, this project will be loaded into the RAM memory but not executed when switching on the CPU.

Error LED

Parameters of the Processor Module

On On The error LED lights up for errors of all classes, no failsafe function activated.
Off by E4 Warnings (E4) are not indicated by the error LED, no failsafe function activated.
Off by E3 Warnings (E4) and light errors (E3) are not indicated by the error LED, no failsafe function activated.
On + failsafe The error LED lights up for errors of all classes and the failsafe function of the I/O Bus is activated.
Off by E4 + failsafe Warnings (E4) are not indicated by the error LED, (no error Display with “diagnostic” button on the LCD possible), the failsafe function of the I/O Bus is activated.
Off by E3 + failsafe Warnings (E4) and light errors (E3) are not indicated by the error LED. The failsafe function of the I/O Bus is activated.
Check Battery On On The presence of the battery and the battery status are checked. If no battery is available or the battery is empty, a warning (E4) is generated and the ERR LED lights up.
Off The presence of the battery is not checked. No warning (E4) is generated. The LCD display “Batt” (triangle) can not be acknowledged! This also applies if a battery is installed but empty.

Behavior of outputs in stop

Parameters of the Processor Module

Off in hardware and online Off in hardware and online In case of STOP, all outputs at the hardware and in the online display are set to FALSE or 0.
Off in hardware and actual state online In case of STOP, all outputs at the hardware are set to FALSE or 0. The online display indicates the status from the last cycle of the user program.
Actual state in hardware and online The status of the last cycle of the user program is kept for the outputs at the hardware and in the online display.
Stop on error class E2 E2 In case of a fatal or serious error (E1-E2), the user program is stopped.
E3 In case of a fatal, serious or light error (E1-E3), the user program is stopped.
E4 In case of a fatal, serious or light error (E1-E3) or a warning (E4) the user program is stopped.

Warmstart

Parameters of the Processor Module

Off Off In case of a fatal error (E2), no warmstart is performed.
On after E2 error In case of a fatal error (E2), a warmstart is performed automatically.
On after short voltage dip A warmstart is performed after a short voltage dip.
On after E2 or short voltage dip In case of a fatal error (E2) or after a short voltage dip, a warmstart is performed automatically.

Reaction on floating point exceptions

Parameters of the Processor Module

E2 failure E2 failure Only for PM59X: If a floating point exception occurs, an E2 error (Err=38) is triggered. The CPU goes to STOP.
No failure Only for PM59X: If a floating point exception occurs, no E2 error is triggered. Using the block FPU_EXINFO in the user program allows to react on a possibly occurred exception.

Flexible configuration

Flexible AC500 Configuration\ \ \

None None No flexible configuration is used.
Flash FlexConf.ini is loaded from Flash.
User Program FlexConf.ini is loaded by user program.
FTP file FlexConf.ini is loaded from FTP.

Flexible configuration timeout

Flexible AC500 Configuration\ \ \

1000 0…65535 FlexConf.ini timeout in seconds [s].
Free wheeling pause 10 0…255 Free wheeling pause in milliseconds [ms]. *)

Start PERSISTENT %R0x

Parameters of the Processor Module

    Start offset for buffered area in PERSISTENT area %R0x
End PERSISTENT %R0x     End offset for buffered area in PERSISTENT area %R0x
     
Start PERSISTENT %R7.x     Start offset for buffered area in PERSISTENT area %R7.x
End PERSISTENT %R7.x     End offset for buffered area in PERSISTENT area %R7.x

*) Setting this parameter to ‘0’ causes the CPU to work with the default setting 10 ms.
