 Stream Valve Switching
The Stream Valve Switching function of D/O is a function to turn On and Off external stream 
valves using D/O signals.
The contact output is turned On and Off at the time set for the Stream valve ON/OFF time in the 
GCM method.
To enable the Stream valve switching function of D/O, One-to-one output (D/O) is required to 
be selected as the stream valve type in the initial hardware confi guration, and as many D/Os as 
streams are required to be initially prepared.

 Contact Input
As for contact input, by using optional D/I cards (up to four cards, eight outputs per card) and by 
using optional DI/O cards (up to four cards, three inputs and outputs per card), up to 32 outputs 
and up to 12 outputs can be output, respectively.
Depending on the initial hardware settings, the contact input must be set to On While Open or On 
While Closed. The initial setting is On While Open unless otherwise specifi ed.
Specify the settings on the D/I setting screen on the GC-HMI EtherLCD, and then verify the 
operation condition on the D/I condition screen on the GC-HMI EtherLCD.
The following six types can be set for contact input.
• Stream Sequence
• Stream
• Range Switching
• Calibration/Validation
• Operation Mode
• Alarm Process
 Stream Sequence
The Stream Sequence of D/I is a function to give a command to change the measurement status 
to the status of a specifi ed stream sequence number for a specifi ed GCM using contact input as 
a trigger.
Eight patterns of stream sequence can be used for each GCM.
