Case Study: Siemens PLC Upgrade Location: Decoma Sybex, Banbury |
|
| Project Description: MCS Control Systems were contracted by Decoma Sybex to upgrade two of their Siemens PLC’s in the Primer Premix area from the S5 range to the current S7-300 range. These PLC’s control the paint mixing system that delivers mixed Primer to the Fanuc Robots on the Bumper Spraying Line. This functionality was to be exactly replicated in the new S7 PLC’s. | |
| Approach: On the initial site survey, the existing S5 PLC code was uploaded and the system functionality was verified and recorded. The software was then converted to S7 and internally tested using simulation software against an agreed set of testing requirements.
The Bumper Spraying Line is critical to the plant operation and this transplant had to be approached with each phase planned in detail along with contingency plans in place to minimise any downtime. During commissioning, our first step on site was prove the Robot Interface. Rigorous functionality tests were carried out on “Ghost” jobs to validate the robustness of the PLC software prior to launching into production. |

Results: Working closely with the End User the new S7 PLC systems were installed and commissioned over a 5 hour period with no down time and disruption to production |
