XM Open System Advantages
In contrast to all other automation suppliers XM provides an open automation solution. This approach has numerous advantages in project delivery for the project company/end user, both in cost savings and project control/co-ordination overhead.
The open system approach also provides a far more sustainable approach, removing the need for international travel, and allowing far greater use of existing components when performing system upgrades.
|Closed System||Open System|
|Key||PC = Project Company/End User||AC = Automation Company|
|Equipment Supply||AS provides 30-75% of the project value – which then needs markup from the PC – adding to overall project costs, and will vary with specification changes. No added value from the PC||XM costs are <5% of project supply. Clear pricing for any additions /removal of axes, control desks. PC able to use own design/manufacturing/purchasing capabilities for the automation system, contributing to overhead.|
|Project Timelines||Close co-ordination required with AS on all design/delivery/site timelines. Co-ordination of personnel, project co-ordiantion. All add to project overhead costs, and stress.||All project timelines/coordination in hands of PC. No need for XM involvement in project delivery beyond when control desk required (if purchased). PC can run the project independently, saving time, and cost.|
|Project involvement||No need for XM involvement, changes to timeline/equipment specs have no effect on HMI. PC can configure system|
|Project cost overruns||Changes to specification/timeline/||Clear, simple pricing from XM, project changes will have|
|Support||AC charges yearly fee for support contract||Email support/softwre updates provided within the license.|
|Servicing||AS needs to visit sit yearly for 2-5 days (depending on size).||All on site servicing can be undertaken by PC, with remote support as required from XM (usually minimal).|
|Maintainance||AS equipment often needs return to base for repair, warranties on equipment need to be dealt with through AS.||PC can repair maintain XM desk, and fit spare parts as required.|
|Sustainability||Low Requires 8-10 fights for sales/project co-ordination/installation/commissioning. Further 1-2 flights a year for supervising/support. Requires AC’s components to be used, replacing existing equipment.||High All work undertaken remotely, no need for XM visit at any stage of the process. XM is control system agnostic, ability to design control system around existing components/equipment.|
