11.1.1.3.3 Status Register
This is read-only register 30. It contains a number (an enumeration) indicating the status of the CMS. See table 7A
11.1.1.4 Bitmap Functions
11.1.1.4.1 Status Flags Bitmap
This is read-only register 31. It represents the states of various items in a bitmap format.
-Bits 0-2 are so that external equipment (for example RMF-View or a PLC/MMI) can display, update and log results
intelligently.
-Bits 3 and 4 can be used to monitor the test progress.
-Bits 5-10 are used to generate alarms. Depending on the selected alarm mode, they operate the alarm relay
output(s). But they can also be monitored directly by a PLC/MMI program and used to drive indicators, for
example.
-Bit 11 is used internally to detect that the CMS is being controlled by Modbus (from a PLC or by RMF-View).
-Finally bits 12-14 reflect the state of the CMS ``start signal’’ input and alarm output relays.
