How SmartX server and the I/O modules communicate with each other on the communication bus.

How can we help you today?

The communication bus enables serial (RS-485) communication between the SmartX server and the I/O modules. The SmartX server can be either a SmartX AS-P server or an Automation Server. The SmartX server controls and supervises the communication on the communication bus. The I/O modules also monitor their communication status. When a new I/O module is configured and connected to the I/O bus, the SmartX server automatically detects the new I/O module.
