CLOG Error (CX Style Number S3 or Later)
Set the method for dealing with abnormalities in the channel data for CLOG, an operator
for the PV/SP computation function and analog retransmission.
Error: Process as a computation error
Skip: Skip any abnormal data and complete the computation
Event Output (CX Style Number S3 or Later)
Common: Set a common event output setting for all program patterns
Separate: Set the event output for each program pattern
Internal Loop
For each loop there are [Control Setting] and [Burn-out/Tuning] items.
LOOP
Select the loop number to which the settings apply (CX1000: 1 and 2. When 4 selected
for CX2000 4/6LOOP: 1-4). Only the loop numbers for the loops specified in the system
configuration settings appear in the list.
[Control Setting] Tab
Contains the control settings for internal loops.
• Control Action
Control Mode
Select the control mode from [Basic], [Cascade], [PVSwitching], or [Retrans] (Style 3
or later). For a loop with no control, select [OFF]. When selecting [Cascade], because
of a common setting between two loops of a control output terminal block, when you
set loop 1 to cascade, for example, loop 2 can also automatically be set to cascade. If
you make a change such that the smallest loop number changes (other than selecting
OFF), all program patterns are initialized.
Method
Select the switching conditions of two measurement inputs from [Range], [PVHigh], or
[Signal]. You can only make this selection when [Control Mode] is set to [PVSwitching].
