Communication with devices by the Johnson Controls company
For communication of the PROMOTIC application with Johnson Controls
PLC's an ActiveX driver
was created. The driver is determined for communication via the computer's serial port by the N2Bus
The driver supports the following types of controllers: DX9100
, even time programs can be edited), TC91xx
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.
The usage of the PmaActiveX object requires purchase of the "PmActiveX" licence. With the freeware version PmFree, or when developing the application (with development environment for tersting purposes), this component is always functional.
