Local Safety Network Gateway and Modbus devices

LSNG publishers

LSNG Secure Parameters are mapped into publishers when their corresponding Signal is created in the LSNG configuration. Referencing them does not affect their mapping. Each LSNG supports as many as 4 publishers.

Secure data from the LSNG appears to the LSNB just like data from a CSLS and can be mapped to be sent to other LSNs. In addition, commands to the Modbus devices can come from CSLSs on other LSNs through the LSNB.
