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.
