General Compliance with OPC standards No effect on PS output due to failure of remote control Restart of OPC remotely Not send set points automatically at startup – read from

device PS shall maintain its set points during PS power failure? Genuine device and cache access Interactive list of device functions

OPC SERVEROPC SERVER

Maintenance To support future versions of Windows and OPC

standards To support future versions of PS firmware

Configuration Allow appropriate management of the fieldbus Human readable configuration file (such as XML) Obtain actual configuration by scanning Setting of ranges for analog values and setting of the

dead band
