Introduction
This topic describes the Control Expert Device DDT tab for a X80 remote drop that includes a 140CRA31908 adapter module.
A derived data type (DDT) is a set of elements with the same type (ARRAY) or with different types (structure).
This is the I/O structure type when an X80 remote drop with a 140CRA31908 module is installed in an M580 system (where QSA represents the 140CRA31908 module): T_Q_QSA_DROP_EXT_IN
In the default DDT name, the drop number is represented by d#. For example, the second drop has the default DDT name EIO2_d2_DROP.
Access the Device DDT Tab
Access the Device DDT parameters in Control Expert:

2: CRA module is stopped.
3: CRA module is running.
CRA_DIAGNOSTIC (WORD)
bit 0: GLOBAL_IO_HEALTH
BOOL
0: At least one I/O module in the remote drop reports bad health.
bit 1: CCOTF_IN_PROGRESS
BOOL
CCOTF is in progress.
bit 2:CCOTF_INVALID_CONF
BOOL
CCOTF configuration is not valid.
bit 3: IOPL_MISMATCH
BOOL
There is an output data mismatch. The modules in the rack are not the same as the modules configured in the PLC.
bit 4: SWITCH_CHANGE
BOOL
The rotary switches settings have changed since the last power up.
bit 5: DROP_COM_HEALTH
BOOL
This bit shows the remote drop communication health (set to 1 in the remote drop).
bits 6...7
(reserved)
bit 8: REMOTE_IO_ERROR
BOOL
1 = One of these conditions is met:
  • The 140CRP93•00 is missing.
  • The 140CRP93•00 has a detected error.
  • Communications with one or more remote drops lost.
NOTE: Refer to RIO_ERROR_CODE values for details on the detected IO error (see below).
0 = The 140CRP93•00 is operating normally and it sees Quantum S908 remote drops.
bit 9: MASTER_STATE
BOOL
1 = 140CRP93•00 is the S908 bus master of the remote drop.
0 = 140CRP93•00 is not the S908 bus master.
bit 10: INPUT_READY
BOOL
1 = S908 inputs are ready.
0 = S908 inputs are not ready.
bit 11: CCOTF_ALLOWED
BOOL
1 = CCOTF is allowed on the RIO bus.
0 = CCOTF is not allowed on the RIO bus.
bits 12...15
(reserved)
CYCLE_CURR_TIME
UINT
This word indicates the execution time of the last CRA cycle. Its values (0...65535) have a resolution of 0.01 ms. Therefore, the last cycle time is between 0 and 655 ms.
CYCLE_MAX_TIME
UINT
This word indicates the longest CRA cycle execution time since the last start. Its values (0...65535) have a resolution of 0.01 ms. Therefore, the last cycle time is between 0 and 655 ms.
CYCLE_MIN_TIME
UINT
This word indicates the shortest CRA cycle execution time since the last start. Its values (0...65535) have a resolution of 0.01 ms. Therefore, the last cycle time is between 0 and 655 ms.
TIME_STAMP_RECORDS
UINT
number of time stamp records available in the remote drop local buffer
CRP_VERSION
WORD
firmware version of the 140CRP93•00

  • 20: The CRP is hot swapped or connected in a wrong slot
  • 30: Incorrect CRP diagnostic sequence
  • 40: Quantum S908 Adapter internal state error
