How to tell when running on a Simulator

[Andrew S]

I'm loving the new simulator functionality that allows me to use programs for a 'real world' PLC model on the sim.

One thing I'm curious though, is how my programs can tell whether I'm actually running on a sim or a physical PLC. Since $PLCType and $PLCSubType now show the value of the physical PLC I wrote the program for, I've no longer got that visibility (or do I?). I know I can start the sim manually and connect, which would adjust those variables appropriately, but I'd really like to avoid that if possible.

It would be nice to have a $SimActive (or something) bit flag that I can query at runtime.

Andrew.

That would be easy. In the meantime, check the serial number (SerialNum). Serial number of real hardware will always be 00:E0:62:XX:XX:XX

That'll work for now. Thanks Bob.

Added. Will be in 2.7.
