Reading Diagnostic Data

Summary	Thirty-five contiguous registers (45357 through 45391) in the island bus data image
	(See The Data Image, p. 166) are reserved for diagnostic data about the
	Advantys STB system. The diagnostic registers have pre-defined meanings, which
	are described below.
Master Devices	The diagnostic registers can be monitored by a Modbus over TCP/IP host or the
	STB NIP 2212 embedded web server. The master devices use Modbus messaging
	(See List of Supported Commands, p. 135) to read and write diagnostic data to
	specific registers in the diagnostic block of the process image.
	Note: An HMI panel or a device running the Advantys configuration software can
	also exchange data with an island via the (CFG) port (See The CFG Interface,
	p. 33) on the STB NIP 2212.
