CLOG Error (CX Style Number S3 or Later)
Set the error handling when the channel data for CLOG, which is an operator for PV/SP
math and retransmission, is in error.
Error: Handle as a computation error
Skip: Skip the erroneous data and compute
Event output settng
On Style 3 Ver. 3.02 or later, event output can be set for each program pattern. To set
the event output for each program patter, select [Separate]. To set the event output for
all program patterns, select [Common].
Internal Loop
For each loop there are Control Setting and Burn-out/Tuning items.
LOOP
Select the loop number 1 to 6 (1 or 2 on the CX1000, 1 to 4 if 6/4LOOP Select is set
to 4 loops on the CX2000) to which the settings apply. Only the loops for which system
settings were entered appear in the list.
[Control Settng] Tab
Contains the basic settings for internal loops.
• Control Action
Control Mode
Select the control mode from [Basic], [Cascade], [PVSwitch], or [Retrans] (Style 3 or
later). For a loop with no control, select [OFF]. Selecting [Cascade], because of a
common setting between two loops of a control output terminal block, when you set
loop 1 to cascade, loop 2 can also automatically be set to cascade, for example.
Method
Select the switching conditions of two measurement inputs from [TCRange],
[PVHigh], or [Signal]. You can only make this selection when [Control Mode] is set to
[PVSwitching].
Program Control (with the Program Control Option)
Turn program control ON or OFF (on style 2 or earlier, the setting is common to the
two loops on a single control output terminal block). This setting applies to both loops
of a single control output terminal block.
PID Control Mode
Select the PID control mode from [Follow-Up] or [Fixed-point]. You cannot make this
selection when [Control mode] is [OFF] for a loop.
