| PLCAddressValues | An integer register in the PLC that points to the first element to be read for indicating active messages. |
| PLCElementBitWidth | Indicates how many bits are in each element as defined by PLCAddressValue. For example, in Modbus 40001 would be a 16 bit integer. |
| PLCNumberOfElements | Specifies the number of consecutive elements to concatenate their bits for messages. |
| ValueBitMask | Integer value use to mask which bits are to be interpreted for message |
