The Modbus RTU slave register map shows the "batch cycle counter" as Holding Register (4)02252 (one-based addressing) or 2249 (decimal zero based addressing) on page 47 (pdf) of the 2010 Modbus RTU module manual (attached). That value is a 4 byte Dword. Since the manual describes some values as 4 byte values as "floats" (presumably IEEE754 floating point), a Dword is most like a 4 byte, 32 bit integer. Modbus devices are not addressed by their serial numbers, Modbus devices are assigned a slave node ID number (1-247). But, the converter's serial number is available via Modbus. Register(4)02521 has the converter serial number as a 20 byte string, presumably ASCII characters (page 54, pdf) Attachment USMII_MODBUS_AOM_OI_En_en-US.pdf (64 Downloads)
