AC30 series Variable Speed Inverter
Read Record
The RDREC function block is used to read a record. The record data and
MLEN
input must be
at least
the size of the parameter being read:
•
For a standard parameter either 1,2 or 4 bytes respectively
•
For an array parameter the total number of bytes of all elements
•
For a string parameter the maximum number of characters allowed for the string plus 1 for the null terminator
Write Record
The WRREC function block is used to write to a record. The
LEN
input must be
equal to
the size as the parameter being written to unless it is a
string parameter:
•
For a standard parameter either 1,2 or 4 bytes respectively
•
For an array parameter the total number of bytes of all elements
•
For a string parameter LEN should be no more than the maximum number of characters allowed for the string plus 1 for the null terminator
Endian
The endian type for acyclic read and write requests of AC30 parameters is set using parameter
3135 PROFINET Acyclic Endn
. This does not
apply to the cyclic I/O data which is always Big Endian.
Record Error Codes
If the inverter cannot process a parameter read or write request then the
ERROR
output of the function block will be set TRUE and the
STATUS
output will be set to one of the following error codes:
Code
0xDE

0xDF
Write Response
Decode
0x80
PNIO Read/Write
Code 1

Write Length Error
0x82
Invalid Slot or Subslot
0x84
Invalid Area API
0x86
