EasyBuilder Pro provides system register LB-12358, which allows switching to off-line simulation mode on HMI, and running simulation on HMI without connecting a PLC.

Scenario

FAn equipment salesman would like to download a project that he carefully designed to an HMI for demonstrating in front of his customer. Formerly he should connect the HMI to a PLC to simulate project operation. Now all he has to do is switching to off-line simulation mode on Weintek HMI, and the demonstration can be easily carried out without the need for other equipment, which greatly simplifies the job.
