10.2 SOP Development and Operation
All Siemens LD system programs must adher to Siemens standard procedures. Failure to do so
may result in damage to the drive and could void the system warranty.
The SOP le is written by Siemens and adhers to Siemens standards for protection of the drive.
The SOP can be modied by trained personnel for changing requirements. SOP testing is
performed at the Siemens LD facility.
The SOP le is downloaded to the drive in non-volatile memory. The operation of the SOP is
similar to a PLC in that it reads from top to bottom and left to right on a cyclical basis. The drive
must be in an idle state, that is, with output disabled for a new SOP to be downloaded and
started.
