SIMOVERT MASTERDRIVES
Starting an INDEX Command,
first write the index in register
command code
(RWwm+2). Bit 10 has to be 0 and Bit 11 has to be 1!
These two bits will be masked out by CBL before storing in temporary
buffer PKW request IND
. All other bits will be sent transparently to the
converter. If you want to write a 32 bit parameter, put the high word (bit
31...16) into register written data
(RWwm+3). Now you can activate
control bit command code execution request
(RYnF). CBL stores the
INDEX-Command
in IND and written data in PWE2 of the PKW
request data structure. CBL immediately acknowledges the command
by placing 0000 into register reply code
(RWrm+2) and activating
control bit command code execution complete
(RXnF).

Rules for INDEX Command:
♦
If you read a parameter or parameter description, the register
written data
(RWwm+3) is irrelevant.
♦
If you want to write a 16 bit parameter, the register written data
(RWwm+3) is irrelevant (interesting only for 32 bit operands).
♦
If you have an non indexed parameter, you don’t need the INDEX
Command
♦
Depending on type of converter the grey marked fields in INDEX
Command have additional features. Refer to the documents of the
converter. CBL transports all bits (except bit 10 and 11) transparent
to the converter.
Starting a PKE Command,
first write the PKE information in register
command code
(RWwm+2). Bit 11 has to be 0! If you want to write a
parameter, put the data word (bit 15...0; or lower word from 32 bit
operand) into register written data
(RWwm+3). Now you can activate
control bit command code execution request
(RYnF). CBL stores the
PKE-Command
in PKE and written data in PWE1 of the PKW request
data structure. CBL sends a PKW request to the converter.

When CBL receives the answer (PKW reply), it writes PWE1 into
register read data
(RWrm+3) and fills the register reply code
(RWrm+2). The reply code is depending on the length of the answer
(16 bit operand = 0003; 32 bit operand = 0004). If there was an error at
the PKW sequence an error code (800Xh) is filled into register reply
code
. CBL closes the PKE Command by activating control bit
command code execution complete
(RXnF).
CBL controls the time between starting PKE Command sequence and
the end of the handshake. If there is no PKW reply by the converter
after 40 seconds the PKE Command
is closed with reply code 8004
(timeout). During normal operation, a PKW request is served in 20 to
150 ms, depending on the type of MASTERDRIVES unit.
