Simulation for CSLS1508

I am looking for advice regarding the ability to simulate the CSLS1508 logic solvers.

I look at this webpage and it leads me to believe there is a solution for testing CSLS1508 configuration without the CSLS hardware.

https://www.emerson.com/en-gb/automation/control-and-safety-systems/safety-instrumented-systems-sis/deltav-safety-instrumented-system/deltav-sis-virtualization-and-simulation

Is this truly the case?

If so is it implemented using virtualised CSLS1508 (in the VM vsphere environment where you commission as though real hardware) or is it possible at v13 or v14 to assign CSLS1508s to the ProPlus (as it is for SLS1508 logic solvers)

Any advice/information from a user would be welcome.

Many thanks,

Neil

  Hi Neil,

  
  

  You can assign the logic solver to the Pro+.

  
  

  If I remember correctly it's only possible to enable channel simulation when assigned to Pro+ and simulation isn't available when assigned to hardware.

  Thanks for this reply, at what version.
  
  Version 13.3.1, you can assign SLS1508 (Classic I/O Type SIS Logic Solvers) but I don't believe you can assign CSLS1508 (CHARM SIS Logic Solvers)
  
  Does Version 14.3 allow assignment of CSLS1508s to the ProPlus?
  
  Am I overlooking something?

  Hi Neil,
  For a SLS1508 it is possible to assign them to the Pro+ and emulate them there. For the CSLS it is only possible to run them in virtual studio. There is no option to simulate CSLS on the Pro+.

  Hi Rafael,
  
  Many thanks for the confirmation, as I suspected.
  
  Neil.

  Hi Neil,
  For a moment there, I thought we had a new type of logic solver :)
  Our original Logic Solver, in the DeltaV M-Series form factor is the SLS1508. More recently we launched DeltaV SIS with Electronic Marshalling which uses the CSLS Logic Solver and CHARMs technology.
  As Rafael has already answered, you can create "Simulated" SLS1508 Logic Solvers to run either on the ProPlus or also on Application Stations if you have them. You can do a certain amount of SIS Software Module testing on the Simulated SLS1508's before transferring your modules to CSLS, but eventually you will run into some of the differences. Then you need the Virtual CSLS.
  Virtual CSLS have been available since v13.3, and are also available at v14.3. Simulated SLS1508 have been available for a long time (v10 or before), and are still available at v14.3.
  I believe you can also run the Virtual CSLS in a VMWare environment.
  Regards,
  Andy

  In reply to AndyCrosland:

  To recap, the SLS1508 is simulated in the PRo Plus and App Stations, where as the CSLS (no such thing as a CSLS1508) can be virtualized.
  
  As a VM, the CSLS can be run in either Hyper-V with DeltaV Virtual Studio or as a VMware machine. The VM images are available from Emerson in the Virtual Studio Client bundle for both Hyper-V and VMware.
  
  In v13, the virtual CSLS allowed you to manipulate the Input values via the Input Block Simulate parameter, either manually or via OPC.
  
  In v14, the IO simulation has been expanded to allow writing to the DST signals. an application called Device Signal Simulator is provided in DeltaV v14 that allows you to interact with the IO of a virtualized CSLS or SZ, SX, MX, SQ, MQ or PK series controllers. there is also in a CHARM Simulate application, intended to work with CIOC's, including physical CIOC in Simulate mode, but this does not work with CSLS.
  
  Note that you cannot mix and match Virtual Machine Logic solvers and Physical Logic Solvers on the same Local Safety Network, and the SZ controller must also match the Logic Solver instances (virtual or physical).
  
  Eventually, you have to validate the SIF and its field devices as a whole before it can be put into service, but virtualizing the logic solvers allows you to fully verify the Logic solver and all system functions prior to final validation testing at site.

  Thank Andy and Andre,
  
  Okay "CSLS", my bad.
  
  Thanks for all advice.
