10 to 20 hours time advantage for on-call service

A seven month endurance test was successful in all respects: The routers are very reliable and the support by INSYS is extraordinary. We’ll develop new markets primed like this.

Initial situation

he heat station operation includes troubleshooting besides operational management. Failures often remain unnoticed during daytime if the heating failed at night and there was still enough warm water for a shower in the morning.

If tenants complain after returning from work, repair services must be organised under pressure.

  • Open up new, profitable business areas

Detailed requirements:

  • Permanent availability of the INSYS Smart Devices

  • Omission of wasted services due to technical false alarms
  • Automatic failure reporting to central HECOS server

  • Automatic processing of the “Done” message and alarm deletion

  • Detailed failure reports and remote access that all spare parts can be carried with the first service

  • Mostly unattended control center

  • Message dispatch via cellular radio for plug & play installation independent of the customer’s infrastructure
  • Encrypted data communication for remote maintenance

Solution

he most cost-effective and technically perfect solution:
in the heating plant:

  • IMON-G100 with Monitoring App from INSYS icom for full monitoring of all values in the registers of the Siemens micro controller LOGO!™
  • Monitoring App in IMON-G100 dispatches messages via HTTP – and acts as cellular VPN router for remote maintenance at the same time
  • Encrypted VPN connection via icom Connectivity Suite – VPN.

The most cost-effective and technically perfect solution:
in the control center:

  • Self-programmed HECOS server from Messtechnik GmbH & Co KG processes incoming HTTP failure messages and dispatches SMS/e-mail to service technician.

Summary

„We’ve needed alternatives and have found the INSYS fault monitors quite quickly since they ‘have a way with’ the Siemens LOGO!TM.
A seven month endurance test was successful in all respects: The routers are very reliable and the support by INSYS is extraordinary. We’ll develop new markets primed like this.

Therefore, we’ll equip all existing and new customers with INSYS fault monitors and the icom Connectivity Suite – VPN for VPN connection.“
