8 Output Modules HIMax8.7 Checklists for Safety-Related Digital OutputsHIMA recommends using the following checklists for engineering, programming andstarting-up safety-related digital outputs. The checklists can be used for helping withplanning as well as to demonstrate later on that the planning phase was carefullycompleted.When engineering or starting up the system, you can fill out a checklist for each of thesafety-related output channels used in the system to verify the requirements to be met. Thisis the only way to ensure that you have considered and clearly recorded all requirements.The checklist also documents the relationship between the external wiring and the userprogram.8.7.1 Checklist for the X-DI 24 01 Digital Output ModuleHIMaxChecklist for Engineering, Programming and Start-upCompanyV.1.0LocationDesignationSRSOutput no.Safety-Related Digital Outputs of the X-DO 24 01 ModuleSeq.
