4 Technological control panel points
managed by LMS
4.1 Supported technological plant item
The integrated systems support any technological plant item that complies with the FSS
requirements and communicates with FHI Pad using the Cerberus Dati Standard Pro-
tocol.
4.2 LMS technological point modeling
The LMS workstation accesses a subset of the data points configured in the FSS sys-
tem through the FHI Pad interface. This subset of points will be modeled for LMS by the
FHI_PAD in order to emulate a Cerberus Dati CMX cluster.
CMX cluster support is available with LMS V2.4 and later.
4.2.1 Digital points
Technological points are modeled in the LMS by emulation of a cluster of CMXs (Cer-
berus Dati Multiplexer) performed by FHI Pad.
CMX communicates using CDSF (Cerberus Dati Standard Format) as application level.
The technological points are grouped together according to the CMX data structure.
Each CMX cluster is composed of up to 32 CMX units. Each CMX unit has 24 digital
points according to the following table:
Subtype Description
4 24 digital input
5 16 digital input and 8 digital output
6 Reserved to cluster unit 0 (for compatibility with NISE_Pad)
7 24 digital output
Each combination corresponds to a subsystem subtype for LMSmodular configuration.
The following tables present the technological points allocation on the CMX cluster
structure:
CMX # 1, First unit of the cluster, local address 00H, subtype 6

01 Link status with FSS
02 Subsystem scan status
03 FSS general status
