8.1.5.2 Parameterizing the parameterizing enable and process-data
interconnections (2nd step)
During start-up, an interface with the USS protocol must be explicitly
enabled for parameterization in order to be able to change (= write) the
parameters of a SIMOVERT MASTERDRIVES via this interface − this
applies to the parameters of the basic unit (P/U parameters) and to the
technology-board parameters (H/L parameters).
Access to the SIMOVERT MASTERDRIVES via USS protocol is only
possible if, during start-up, the PKW area is appropriately defined to
contain 3, 4 words (fixed length) or a variable PKW length (= value 127)
in the useful (net) data area.
The following rules apply to this:
♦ All parameters (P, r, U and n parameters of the basic units, or H, d,
L and c parameters of the technology board) can be read out via
any interface. For reading purposes, it is not necessary that the
interface has been enabled for parameterization.
P, U, H and L parameters: Can be read and written
r, n, d and c parameters: Can only be read
♦ Parameterizing enable is specified in parameter P053 (parameter
access). This parameter can always be written from any interface.
♦ Several interfaces can be in possession of a parameterizing enable
simultaneously.
