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.
NOTE
The parameters OUT_SCALE and PV_SCALE need reconfiguration in case of:
• Factory Reset
• Unit change of the Process Variable (PV)
4.4 Setting of Write Protection
A write protection is a function to forbid changing of parameters. It is possible to set the software write
protection by the Physical Block parameter WRITE_LOCKING. When WRITE_LOCKING is "0: Lock", the
status of write protect becomes protected mode. When WRITE_LOCKING is "2457: Disabled", the status
becomes unprotected mode.
