5.1 Overview
The site-specific AutroSafe configuration data and the BSL-330
register mapping (Modbus register, see
Modbus Register Mapping
)
are used as input for the configuration of the external PLC equipment,
which is to be considered as the
master modbus
device.
The BSL-330 module reads all status messages from AutroSafe on a
protocol called AutroCom, and keeps the accumulated results in a list
of registers internally.
The PLC polls the BSL-330 module for reading its registers. It expects
a response within a defined time period. Communications can be over
various serial mediums. The one used here is the MODBUS RTU
protocol over an RS485 link.
The PLC takes action on some (or all) of the status messages from
AutroSafe.
The illustration below gives an overview of the data communication.
