4.3 Cyclic Data Exchange
The RAMC is preset in factory and should work after integration into the system. In case of parameter
adjustment the items described in former section need special care to ensure cyclic data exchange.
The OUT parameter transfers Value and Status of the device.
The parameters OUT_SCALE and PV_SCALE need reconguration in case of:
• Factory Reset
• Unit change of the Process Variable (PV)

becomes unprotected mode.
