1.2 Module Usage in a System
This section describes the operation of the GPIO module in an MCN display
system.
Input Monitoring and Output Control
Off/on status from devices connected to inputs of the GPIO is sent to a MCN User
Interface Module over the MCN network. The User Interface Module (such as
the HIB-IP) then transfers the status to the PC running MCNRCD Software. The
MCNRCD Software displays the device status information on the PC monitor.
Likewise, off/on states of devices connected to GPIO outputs can be controlled
from the MCNRCD Software.
System Example
Figure 2 shows an example system to monitor and control equipment I/O using
GPIO modules. In this system, HIB-IP modules are used to “tunnel” these I/O
signals over an IP network, for display on a PC.
