• Screen No. 9021, 9022, or 9023
The Device Monitor function’s screens are displayed. The displayed
screen’s screen number (9021 to 9023) is notified to the host. (These
screen numbers are not supported by the NT21.)
The Device Monitor function can be used even in RUN mode, although this
is the case only when the PT is connected to a PC that can use the Device
Monitor function.
The PT can continue operating even when executing the Device Monitor
function. The PT continues monitoring the status of the PT status control
area, logging trend graph data, and monitoring the status of the alarm his-

When resetting from the Device Monitor function, either terminate the De-

by executing a PT status control area operation from the host.
