APPENDIX D
Flexible Module
The Flexible Format implements I/O data exchange that supports direct map-
ping of Inverter Modbus registers in the I/O area. This offers fieldbus- and pro-
file-independent control of the Inverter. The exchanged registers are
configured by setting Inverter registers P160 - P179 to the appropriate
Inverter Modbus addresses.
Note
Set P182 = 2 for the Option Board to support the Flexible module
Note
The Inverter places some restrictions on the Modbus register selection. For a
Modbus Register to be mapped for output data exchange, it must be a run-
mode edit register that provides write-access. Double-word Modbus registers
must be mapped in sequence: low-word following high-word. It is not allowed
to map the same register more than once in the output area.
Refer to Section B-4-2 of the MX2 Inverter user's manual for a list of the
Inverter registers that provide write access.
Refer to Section “4-4 Register Number List” of the RX Inverter user's manual
for a list of the Inverter registers that provide write access.
Refer to Section 3-2-3 of the MX2 Inverter user's manual for an explanation on
run-mode edit registers. Also note that the run-mode edit requirement can be
disabled with b031.
Refer to Appendix 1 of the RX Inverter user's manual for an explanation on
run-mode edit registers. Also note that the run-mode edit requirement can be
disabled with b031.
Tip
When using Flexible Format, the Inverter is controlled via Modbus registers.
I.e. set A001/A002 = 3 and A201/A202 = 3 to make use of the Modbus control
registers for typical Flexible Module use.
