mbusRecordSlaveInfo (Functionblock)

This function block will provide information about a slave.

For  M-Bus this information must be requested with mbusDataRequest.

For Wireless M-Bus, the data must have been received with mbusDataReceive.

Input:

handle : SYSHANDLE

A handle to the connection

Output:

id : DINT

The device id / serial number of the slave.

manufacturer : STRING

The EN 61107 manufacturer ID as a string.

version : INT

The version number of the slave.

medium : INT

The medium of the received data.

pri_addr: INT

The primary address of the slave. -1 for wireless M-Bus.

sec_addr: STRING

The secondary address of the slave.

accessnumber : INT

The access number of the package.

enc_state: USINT

The encryption state of the package.

signal : SINT

The signal strength of the package in dB. Only available for Wireless M-Bus. 0 if not available.

status: INT

Status field from slave.

ready : BOOL

TRUE if the information is available, FALSE if not.
