Outputs 8 independent constants.
Ramped Switch Switches two analog inputs (or constants) with a
ramp.
Bank Selector Records the PID parameters (SP, P, I, D, MH, ML)
in up to 8 sets in advance, and switches the PID
parameter for Basic/Advanced/Blended PID
Blocks according to the analog input range
(zone) or input bits.
Split Converter Inputs the MV from the Basic PID block or Ad-
vanced PID block, converts the MV into two
analog outputs for V characteristics or parallel
characteristics (e.g., MV for heating or cooling)
and outputs them.
Constant
ITEM Setting
Constant ITEM Setting
(See note 1.)
Writes the constant to the specified ITEM at the
rising edge of the send command contact.
Variable ITEM Setting
(See note 1.)
Writes the analog signal to the specified ITEM at
the rising edge of the send command contact.
Batch Data Collector
(See note 1.)
Stores each of max. 8 analog inputs to buffer by
a certain timing within sequential processing.
Pulse Train
Operation
Accumulated Value In-
put Adder
Adds up to four accumulated value signals.
Accumulated Value Ana-
log Multiplier
Multiplies analog signals by the accumulated
value signals.
Accumulator for accu-
mulated value input
Converts 4-digit accumulated value signals to 8
digits.
Contact input/Accumu-
lated value output
Counts low-speed contact pulses, and outputs
8-digit accumulated signals.
Accumulated Value In-
put/Contact Output
Converts 4-digit accumulated value signals to
low-speed contact pulses before they are output.
Others Analog/Pulse Width
Converter (See note 1.)
Changes the ON/OFF duration ratio in a constant
cycle duration so that it is proportional to the
analog signal.
Sequence
Operation
Contact Distributor Connect contact signals between function blocks
in a 1:1 connection.
Constant Comparator
(See note 1.)
Compares up to eight sets of analog signals and
constants, and outputs the comparison results as
contacts.
Variable Comparator
(See note 1.)
Compares up to eight pairs of analog signals,
and outputs the comparison results as contacts.
Timer (See note 1.) 2-stage output type addition timer for forecast
values and reached values. Can also output the
present value.
ON/OFF Timer
(See note 1.)
Timer for performing ON-OFF operation at preset
ON and OFF times.
Clock Pulse
(See note 1.)
Outputs a clock pulse at the setting time interval
for a single operation cycle.
Counter (See note 1.) 2-stage output type addition timer for forecast
values and arrival values. Can also output the
current value.
Internal Switch
(See note 1.)
Temporary storage contact for accepting relays in
the Step Ladder Program block.
Note: (One internal switch is already allocated
as “temporary storage” in CX-Process
Tool. )
Level Check
(See note 1.)
Checks an analog input for 8 levels and outputs
a contact corresponding to the level. The level
number is also output as an analog value at the
same time.
