CHARMs Smart Logic Solver (CSLS) SIShardware overviewCSLS SIS hardware consists of:CHARMsSmart LogicSolvers (CSLS)

CSLS process LS CHARM signals and run the SIS modules that containthe safety system logic. Redundant CSLS can support up to 96 LSCHARMs. The maximum number of LS CHARMs (96) are organized ineight banks of 12 CHARMs. Each bank of 12 LS CHARMs is held by aCHARM Baseplate. CSLS mount on CHARMs Smart Logic Solver Carriersand connect to the Local Safety Network through connectors on thecarriers.

SZ Controllers SZ Controllers mount on the SZ Controller Carrier and connect to theArea Control Network and the Local Safety Network through ports onthe carrier. SZ Controllers isolate CSLS from the rest of the system. SZcontrollers receive redundant 24 VDC input through the carrier. AModbus/TCP port on the carrier enables an SZ controller to supportstandalone SIS installations.

CHARMsSmart LogicSolver Carriers

CSLS Carriers are DIN rail-mounted carriers that hold simplex orredundant CSLS and Power Modules. The CSLS Carrier provides 24 VDCinput to the CSLS and to the Power Modules. The Power Modulesprovide 6.3 VDC to the LS CHARMs. The CSLS Carrier houses primary

CHARMs Smart Logic Solver hardware specifications

and secondary Safety Network Ports for connections to the Local SafetyNetwork and a keylock switch that restricts how and when the CSLS canbe unlocked for downloads and upgrades.

SZ ControllerCarriers

SZ Controller Carriers are DIN rail-mounted carriers that hold simplex orredundant SZ Controllers. The SZ Controller Carrier houses primary andsecondary Ethernet Isolation Ports for connections to the DeltaV AreaControl Network and to the Local Safety Network.

Baseplates CHARM Baseplates hold Logic Solver CHARMs (LS CHARMs) and I.S.Baseplates hold LS Intrinsically Safe CHARMs. The baseplates connect tothe CSLS Carrier and to other baseplates through connectors on thebaseplates. Each baseplate holds up to 12 terminal blocks that hold LSCHARMs, and an Address Plug that determines the address of thebaseplate and the CHARMs installed on the baseplate.

Logic Solver(LS) CHARMs

LS CHARMs are single I/O channels that plug into the LS CHARM TerminalBlocks on the CHARM Baseplate. The DeltaV system supports analoginput, discrete input, discrete output (including LS DO redundant DTAand LS DO redundant ETA CHARMs), LS DVC HART simplex andredundant DTA, power output, thermocouple input, and voltage LSCHARMs as well as LS Intrinsically Safe analog input and discrete inputCHARMs.

CHARMs Smart Logic Solver specificationsInstallation notes Redundant CHARMs Smart Logic Solvers (CSLS) install on the CHARMs Smart Logic

Solver Carrier. The CSLS receives 24 VDC input power from the CHARMs Smart Logic Solver Carrier. The CSLS connects to the Local Safety Network through redundant Ethernet ports

on the CHARMs Smart Logic Solver Carrier. A physical keylock switch on the CHARMs Smart Logic Solver Carrier along with an

unlock software function restricts how and when the CSLS can be unlocked fordownloads and upgrades.

SZ Controller Carrier specificationsInstallation notes The SZ Controller Carrier installs on vertical T-type DIN rails. Redundant SZ Controllers plug into the slots on the SZ Controller Carrier. The SZ Controller Carrier provides redundant 24 VDC power for the SZ Controller. The SZ Controller Carrier houses a primary and secondary Ethernet Isolation Port

(EIP). Each EIP consists of an Area Control Network port for connections to theDeltaV Area Control Network, a Safety Network port for connections to the LocalSafety Network, and port activity LEDs. The secondary Area Control Network portalso functions as a Modbus/TCP port. The EIPs are removable. To remove an EIP,depress the button next to the EIP and push it out of the carrier.

Screw terminal connections on the carrier allow an external power source to beconnected to backup the real-time-clock on the SZ Controllers for power outagesgreater than 100 hours. If these connectors are used, the power source must meetthe requirements in the following table.

LS CHARM Column Extenders and cableInstallation notes The LS CHARM Column Extenders are used to extend the power and

communications busses when CHARM Baseplates in a 96 CHARM system areinstalled on multiple DIN rails.

The bottom column extender can be connected to a CHARMs Smart Logic Solver(CSLS) Carrier or to a baseplate depending upon the physical location of the carrierand the baseplate. For example, if the CSLS carrier only is installed on a DIN rail andthe baseplates are installed on another DIN rail, the bottom column extender wouldbe connected to the CSLS carrier and either another bottom extender or topextender could be connected to a baseplate on the other DIN rail. Refer to thesecond image in this topic.

The top column extender can be connected to baseplates only. To connect the cables between the extenders, connect primary to primary and

secondary to secondary. Three cable lengths are available for use with the extenders:


23

- 0.5 meters (1.64 feet)- 1.0 meters (3.28 feet)- 2.0 meters (6.56 feet)

A maximum of four extender pairs can be used and only one extender pair canexceed 0.5 meters (1.64 feet).

Terminal Block. A sensor connected to two of the wiring terminals provides Cold Junction

Compensation. The sensor is provided with the CHARM. Color coding for thermocouple wires varies from country to country. Refer to your

local standards for the appropriate color code.

LS Output CHARMs specificationsLS DO 24 VDC CHARMs specificationsThe DeltaV system supports the LS DO 24 VDC DTA CHARM, the LS DO 24 VDC(Redundant DTA) CHARM, the LS DO 24 VDC ETA CHARM, and the LS DO 24 VDC(Redundant ETA) CHARM.Installation notes The LS DO 24 VDC DTA CHARM requires the CHARM Terminal Block. This CHARM is

suitable for use in SIL 3 de-energize to trip (DTA) applications. The LS DO 24 VDC ETA CHARM requires the CHARM Terminal Block. This CHARM is

suitable for use in SIL 2 energize to trip (ETA) applications. The LS DO 24 VDC (Redundant DTA) CHARM can use the following terminal blocks:

- The Redundant Terminal Block- For applications that drive a final element that requires more than 500 mA use

the Redundant DTA Relay Terminal Block. The Redundant DTA Relay TerminalBlock has a built-in relay that can handle up to 2 A and the redundancy allows forhigher safety coverage to shut down the process.

- For applications that drive a final element that requires more than 500 mA, andalso requires the use of the baseplate's injected power bus rather than systempower use the Redundant DTA Injected Power Relay Terminal Block. TheRedundant DTA Injected Power Relay Terminal Block has a built-in relay that canhandle up to 3 A and the redundancy allows for higher safety coverage to shutdown the process.

This CHARM is suitable for use in SIL 3 de-energize to trip (DTA) applications. The LS DO 24 VDC (Redundant ETA) CHARM requires the Redundant Terminal Block

or the Redundant ETA Relay Terminal Block. This CHARM is suitable for use in SIL 2energize to trip (ETA) applications.

The LS DO CHARMs have short circuit protection and support line monitoring forsensing field wiring faults such as open and short circuits. Line monitoring is enabledin the configuration.

NoteLine fault detection is not compatible with significant capacitive loading (cable + load > 30 nF)and must be disabled under these conditions.
