  "@Skill.Modbus.HoldingRegister": {
    "name": "Holding Register 4",
    "UUID": "ce30fa69-c291-4813-9cc6-b7897a2bd16a",
    "ACL": { ... },
    "address": 4,
    "format": "uint16",

}

Object Members

name	A string value containing the name of the holding register. The name is used to construct the holding register’s primary key.
UUID	A string value containing the unique UUID of the holding register.
ACL	An optional JSON object containing the element ACL of the holding register. The format of the object is described under JSON Format for ACLs in the Xentara user manual.
address	An integer value containing the 0-based address of the holding register. Must be in the range of 0 to 65535. For multi-register data formats, this must be the address of the first register of the data.
format	A string value describing the data format of the holding register. The format implicitly also specifies the number of registers to read or write.
poll	An optional string value describing the poll in which the holding register’s current value should be queried. The string value must contain the primary key of the poll. If you do not specify a poll, the register’s current value will be unavailable.
