PLCgen test model "negative_zero" fails due to maximum PLC cycle time

CIF model: negative_zero.cif

Generated PLC code: CONSTANTS.xml DB.db MAIN.scl

The PLC code for this test model generates and compiles nicely. However, after downloading it to the PLC, the PLC immediately goes into error mode.

After some further investigation we found that the PLC reaches it maximal cycle time, after which it goes into error mode. The test model is setup to run 30.000 times (c < 30 * 1000, with an edge update of c = c+1). We manually lowered this value, which stopped the error mode from occurring.
