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:

CHARM Terminal Block specificationsInstallation notes The CHARM Terminal Blocks are preinstalled on the CHARM Baseplate. Each
terminal block holds a single Logic Solver (LS) CHARM and provides the keying andfield wiring for the LS CHARM.
The CHARM Terminal Block's keying mechanism sets itself to match the inserted LSCHARM.
To reset the keying mechanism, remove the CHARM Terminal Block from theCHARM Baseplate, flip the terminal block 180, and use your fingers to push the twokeying posts completely in and return the posts to the neutral position. You will heara click when the posts are completely pushed in. When the posts are in the neutralposition, the terminal block can receive a different LS CHARM type.
The following LS CHARMs can use the CHARM Terminal Block:- LS AI 0-10 VDC Isolated- LS AI 4-20 mA HART- LS DI 24 VDC Isolated- LS DI 120 VAC Isolated- LS DI 230 VAC Isolated- LS DI 24 VDC Low-Side

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.
