Communication with PLC devices by the Johnson Controls company

For communication of the PROMOTIC application with Johnson Controls PLC devices an ActiveX driver was created. The driver is determined for communication via the computer's serial port by the N2Bus protocol.

The driver supports the following types of controllers: DX9100 (8454 and 8154, even time programs can be edited), TC91xx, XT and XTM, DR9100, DC9100.

The driver supports up to 6 COM ports. It is suitable for applications where, for example, the number of controllers on one bus is too high and the communication is slowed down.
If the driver is not registered, then it runs in the DEMO mode. DEMO provides real values only in limited time (30 minutes). After this time it provides only 0 instead of real values. After restart it provides correct values again.

Trade terms:
The usage of the PmaActiveX object requires purchase of the "PmDllActiveX" licence. When developing the application in the freeware mode PmFree, or with development environment and while testing it in runtime, this component is always functional.
