Emerson VE4002S1T2B5 - DCS Distributed I/O Unit Module

Reduces programming and commissioning time dramatically.

Bus termination provides added robustness for the

communication bus and is installed at the end of the physical bus.

Label features are available to identify channel usage and

Baseplate identification to help with maintenance.

CHARMs can be added to any existing baseplate

position and autosensed online. Additional CIOCs can be added online.

of the DeltaV SIS™ process safety system. The LSN is a standard

Ethernet network dedicated to the DeltaV SIS system that

enables communication between CHARMs smart logic solvers

(CSLS) and a single SZ controller. The CSLSs communicate

secure parameters and input data to other CSLSs over the LSN.

SZ controllers connect to both the area control network and

the LSN to isolate the CSLSs from the process control system.

Starting with v13. the global safety network (GSN) enables

safety-rated communication among LSNs while allowing

functional segregation on different LSNs. A typical example is

separation of fire and gas (F&G) and emergency shutdown

(ESD) applications over separate LSNs while allowing safe and

secure communication across both applications. Starting with

v14.LTS, the GSN can be logically separated in domains which

are a group of LSNs.
