6. ASCII Server to BACnet Client

6.1. Specific Gateway Introduction

This section describes the integration of BACnet/IP and MSTP devices into ASCII IP or Serial control and
monitoring systems using the ASCII Server to BACnet Client application.
This integration allows any ASCII system to access the signals and resources of BACnet devices as if they were
part of the system itself and vice versa.
The gateway configuration is carried out through the configuration tool.

6.2. Functionality

From the BACnet point of view, the gateway continuously polls the installation or devices, storing in its memory
the values of the points that you previously configured to be read. On the other hand, from the ASCII point of
view, the control and monitoring system reads and writes those stored points.
This is possible because, inside the gateway, all BACnet objects of the server devices are associated with ASCII
objects. This makes the ASCII control and monitoring system perceive the BACnet installation (all the server
devices) as if it were a single ASCII device.
When the gateway polls the BACnet devices, if a non-response is detected, the corresponding virtual signal inside
the gateway will be activated, indicating the communication error to the ASCII system.
