About the 8030-CRM-255

The Sy/Max Class 8030 Type CRM-255 Local IO/Net Interface Module provides a communication interface between a Sy/Max processor and remote I/O on the IO/Net control network. This communication interface provides the means for the processor to read and write to the input and output signals of Sy/Max Class 8030 rack mounted I/O base units.

The local I/O module controls communication between the Sy/Max processor and remote I/O as part of the Passport I/O System.

The 8030 Type CRM-255 Local IO/Net Interface Module is a component in the Passport I/O system. The Passport I/O system also includes the Sy/Max Class 8030 Type CRM 260 Remote IO/Net (RIO) Interface Module and the Sy/Max Class 8030 Type CRM 275 Distributed Remote IO/Net (DRIO) Interface.

The 8030 Type CRM-255 Local IO/Net Interface Module can only be used with Sy/Max Model 400, 450, 600, and 650 processors.

To ensure reliability, install signal line protection devices in environments where interference might cause hardware failures.

Remove power from all local and remote racks before inserting or removing any components including the interface modules and communication cables to prevent possible equipment damage.
