Modbus Register Map (cont’d)
Format (R40,062)
This value determines the format of all unsigned, double-register integers (UINT32),
except for those in the direct parameter access.
0 indicates that the most significant byte (MSB) is given first
1 indicates that the least significant byte (LSB) is given first
For more information on this data format see page 87
Device Identifier (R40,064)
This value identifies the Siemens Milltronics device type and is “2” for the SF 500.
Handshaking Area (Parameter Access)
An advanced handshaking area is built into the SF 500. Use it to read and write 32 bit
parameters.
Mapping
Parameter Read and Write (40,090 – 40,095) is a series of six registers that are used for
reading and writing parameter values to and from the SF 500. The first three registers are
always unsigned integers representing parameters and index values. The second three
registers are the format and value(s) of the parameter.
