4.4 Definition of Module's Extended Diagnostics Data

The Extended Diagnostic Data is reported during startup and initialization

sequence when the master requests diagnostic data from the module. The

Extended Diagnostics is "Device Related" type providing status data (the

extended diagnostic bit 3 in standard diagnostic byte 1 is set = 0). The data

length is normally 14 (0E) bytes displayed in the following format:

Byte(s) Description (HEX)

0 Extended Diagnostics length (normally 14 bytes (0E))

1 to 6 ASCII data for Product Version

7 to 10 ASCII data for Product Name

11 Value of Status Register [0] (see Section 2)

1 2 ... 30 31 32 33 34 35 36 37 38 39 40 ... 60 61
