Debug Simulation in Enhanced IEC*

NOTE: This feature requires Enhanced IEC License.

See also: Debugging Functions in IEC

See also: Enhanced IEC 61131 Guide

 

The Simulator function is similar to Debugging, but logic is evaluated within Cscape, and OCS is not needed. Breakpoints and Single-Stepping Debugging facilities are all supported in the Simulation Mode.

During test (connected mode or simulation) of the program the ST / IL editor shows in a Tooltip the current value of the variable pointed to by the mouse cursor without a special command by the user. Simply hover the cursor on the variable symbol and wait for one second to open the Tooltip. See example below:

The value shown in the tooltip is automatically refreshed while the tooltip is open.

 

Simulation for System Bits

The following system bits are supported in simulation mode.

%S1 (FST_SCN) - it will be 1 for the first PLC Logic scan only & rest all PLC logic scan it will be 0.

%S2 (NET_OK) - will be always a 1.

%S3 (T_10MS) - it's value toggles every scan of the PLC.

%S4 (T_100MS) - it's value toggles every third scan of the PLC.

%S5 (T_SEC) - it's value toggle between 0 & 1 for each 1 sec interval.

%S6 (IO_OK) - will be always a 1.

%S7 (ALW_ON) - will be always a 1.

%S8 (ALW_OFF) - will be always a 0.

%S13 (NET_IO_OK) - will be always a 1.
