REX640 Modbus Communication Protocol Manual

Different advanced customization features are supported by the protocol; these features can be enabled via the Prtl Customization configuration parameter.

The Prtl Customization parameter is a 31-bit bitmask. Currently, bit zero (0) is in use. The setting value for each customization feature is calculated by the following formula: 2^(bit number).
