TECHNICAL NOTE
Block Fault Conditions:
The following table outlines several situations that may cause an error, and will turn on
the blocks “Error” output bit. The block “Error” output will OFF if the EXECUTE bit goes
low.
Internal Fault Bit Cause Note
inRng1
AB000003 Improper cir
number. Out of
range. On the initial pass of the block the bit must
be high or an error will occur. Sets RDA
Error ID (MW3**81) bit 3 on if error state
exists.
inRng2
AB000004 Improper slave
address On the initial pass of the block the bit must
be high or an error will occur. Sets RDA
Error ID (MW3**81) bit 3 on if error state
exists.
snderr
AB00001F MSG-SND has an
error. The MSG-SND internal function has an
error. Refer to ERROR-ID output for
value.
81= function code error
82= address set error
83= data size error
84= line number set error
85= channel number set error
86= station address error
88= transmission part error
89= device selection error
Working Register
This table outlines the data in the Twenty-three registers used by the function block.
There is not usually any need for the user to access any of these bits directly. The
MSG-SND type registers can be further understood by referencing the MSG-SND
function block in the on line help.
Register No Type Name Description
AW00000
Bit 0 IN execute EXECUTE input (XB000000)
Bit 1 Working crlf
If True, a carriage return and Line feed are inserted at the end
of the table.
Bit 2 Working oddnum Reserved
Bit 3 OUT inRng1 Verifies that CIR-NUM input (XW00003) is in range
Bit 4 OUT inRng2 Verifies that SLAVE input (XW00004) is in range
Bit 7 OUT running Directly controls YB000000 (RUNNING Output)
Bit 8 OUT done Directly controls YB000001 (COMPLETE Output)
Bit 9 OUT error Directly controls YB000002 (ERROR Output)
Bit A Working oneshotA Reserved
Bit B Working firstPass
One shot on rising edge of EXECUTE input to initialize RDA &
sets parameters in the message send function
