The Point Multiplex Modules (XM) expanded the binary Input and Output capability of the earliest Metasys installations. These devices were only compatible with NCM database; they do not exist on N30, NAE/NCE, or SNE/SNC systems.
The N2-capable FEC or CGM can easily replace the point multiplexer functionality, but the base-frame hardware configuration leads to some additional expense, in addition to the replacement controller.
Consider the following:
- FEC1611 or CGM09090 controllers replace the XBN, XRE, and XRL Point Multiplex modules.
- Additional M4-XPMs or IOMs are required for most installations.
