z
The response delay does not
include input filter delays.
z
TRC denotes a remote I/O
transfer time. RC denotes a
refresh cycle time set from
J.NET.
z
While a data transfer on remote
I/O or J.NET is suspended, the
input data is held at its value in
effect just before the suspension
of the transfer.
z
No external wiring is required for
the A/D conversion module.
z
This module gives the station
module the appearance of
functioning the same way as the
analog input module (LQA000)
in mode 2.
