COMMUNICATION

8.2.4 SCREEN-MODULES COMMUNICATIONS BUS

The other communications bus is set up by the COM1 port (DISPLAY). This bus allows the

communications between the screen (master) and modules, and has the same features as the

RS-485. One important consideration is the maximum distance of 1.200 m from the master (in

this case the display) to the last slave and the number of measurement modules (slaves) that

can be connected to the bus, which is 32.

This communication between display and measure modules is proprietary communications

protocol.
