The block of measurement data to be written from the IV-S30J to the PC, in step
, can be specified on
the "OBJ-TYPE I/O" screen.
See page 16-23.
When a Sharp PC is connected
The IV-S30J sends write enable command (EWR) to the PC in the following cases.
- When the power is applied to the IV-S30J.
- When a Sharp PC is selected.
- When a write mode nonconformity error (code 10
(H)
) occurs after a result write command (WRG) is
transmitted (when the power is disconnected from the PC).
When a Mitsubishi, OMRON, or Yokogawa PC is connected
The data in items
and
are divided into packets for transmission.
