ANALOG OUTPUT MODULE BLOCK (AOM)
5-54
14
I/O Mismatch (MODMM).................................................................................................... – – R
Even though the I/O mismatch diagnostic may be suppressed and its value not stored with the
active I/O mismatch attribute, the actual I/O mismatch condition can still be determined by this
attribute (value is unsuppressed). This attribute is used to determine if their is an I/O
mismatch when changing the I/O mismatch diagnostic from suppressed to enabled.
YES 1 Diagnostic error is active.
NO 0 Diagnostic error is not active.
15
Board Number (BOARD)................................................................................................... – – R
This is the board number that the physical module is configured for. Currently, the only valid
value is 1.
16
Slot Number (SLOT).......................................................................................................... – – R
This is the slot number that the physical module is configured for. Valid values are 1 to 32.
17
Module ID (MODID) ........................................................................................................... – – R
The module id is read as part of the initialization process. This value is compared with the
configured block type to determine if their is a module mismatch.
18
Extended Error (EXTERR) ................................................................................................– WR
The extended error code is a bitmapped two byte (16 bit) error code from the module that is
presented as a count value. The count value must be converted to binary to decode the
following bit mapped error pattern (1=error condition):
Bit Extended Errors (Lower Byte) Bit Status Errors (Upper Byte)
0 Failsafe Timeout Condition 8 Unused
1 Host Comm. Checksum Error 9 Output Mode (0=Standard, 1=Calibration)
2 Host Comm. Range Error 10 Readback Out of Range
3 EEPROM Comm. Error 11 Readback Invalid
4 EEPROM Calib. Data Error 12 Global Error
5 Host Comm. Invalid Cmd Error 13 Unused
6 Config. Checksum Error 14 Readback Value is Zero
7 Timeout Restart 15 Unused
19
Mode (MODE)..................................................................................................................... CWR
The mode of the block is determined by configuring and/or writing this attribute. Switching
mode is a reportable event.
MAN 0 The block output is the result value, which may be written by the user.
The readback value is updated with the module value.
AUTO 1 The block output is processed using the input data.
20
Action (ACTION)................................................................................................................ CWR
The action applied to the normalized result before it is scaled and put into the result for this
block is determined by configuring and/or writing this attribute.
DIRECT 1 The analog output for the block is not reversed. The direct
calculation is: normalized result = normalized result.
REVERSE 0 The analog output for the block is reversed. The reverse calculation
is: normalized result = 1 – normalized result.
