6.3.4 Status table
The current status of the CoreSense module can be read by using either register 0x117 (analog signal) or
0x97:0x9A (digital alarm). Please use only one of the 2 registers to read the current status of the module.
Status Table is used to decode the "module status" in Modbus address register 0x97:0x9A shown in Table 11 in
Chapter 6.3.2. The code sent by the module for status is a number that can be indexed into the table to decode the
state of the module.
Register 0097:009A is showing less than 64 bits in the table below, because only the alarm IDs that belong to
Stream CoreSense are shown. This register supports not only Stream CoreSense but also other Emerson
CoreSense products (for example CoreSense in Scroll).
