TRC denotes a remote I/O transfer time.
z
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 output data is held at its
value in effect just before the suspension of the transfer, regardless of the status of the
OUTPUT HOLD terminal.
CAUTION
Power off the module before setting the MODE and RANGE switches.
