Flexible Module - Omron 3G3AX-MX2-PRT-E User Manual

The Flexible Format implements I/O data exchange that supports direct map-
ping of MX2-A@ Inverter Modbus registers in the I/O area. This offers field-
bus- and profile-independent control of the MX2-A@ 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 MX2-A@ Inverter places some restrictions on the Modbus register selec-
tion. 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.
Tip Refer to section B-4-2 of the MX2-A@ Inverter user's manual for a list of the
Inverter registers that provide write access.
Tip Refer to section 3-2-3 of the MX2-A@ Inverter user's manual for an explana-
tion 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.
