Master Start
– The coil/register in the NCS
to be used
as a source for writes and a destination for reads.
For queries that involve a range of coils/registers
this value corresponds to the first coil/register in that
range.
Fail Coil
– The coil in the Interface Module’s register
map where errors with the transfer are reported.
Following the execution of a transfer, a value of 1
written to the fail coil indicates that an error has
occurred with the transfer. Refer to *
Note .
It is possible for multiple transfers to use the same fail
coil. In this case, any error in those transfers (logical
OR) will set the coil to true.
Enable Coil
– The coil in the Interface Module’s
register map that is used to control whether or not a
transfer should be executed. A value of zero in this
field means no enable coil is used (i.e. execution of
the transfer can not be inhibited). Refer to *
Note .
It is possible to have multiple transfers use the same
coil, thereby allowing a group of transfers to be
controlled by a single coil.
*Note:
It is possible to leave the Fail and/or Enable
Coil fields off if the coils are not going to be
used. However, it is recommended that a
value of zero be used to explicitly indicate this.
