|
| 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 | Constant ITEM Setting | Writes the constant to the specified ITEM at the |
ITEM Setting | (See note 1.) | rising edge of the send command contact. |
|
|
|
| Variable ITEM Setting | Writes the analog signal to the specified ITEM at |
| (See note 1.) | the rising edge of the send command contact. |
| Batch Data Collector | Stores each of max. 8 analog inputs to buffer by |
| (See note 1.) | a certain timing within sequential processing. |
Pulse Train | Accumulated Value In- | Adds up to four accumulated value signals. |
Operation | put Adder |
|
|
|
|
| Accumulated Value Ana- | Multiplies analog signals by the accumulated |
| log Multiplier | value signals. |

| mulated value input | digits. |
| Contact input/Accumu- | Counts |
| lated value output | |
|
|
|
| Accumulated Value In- | Converts |
| put/Contact Output | |
Others | Analog/Pulse Width | Changes the ON/OFF duration ratio in a constant |
| Converter (See note 1.) | cycle duration so that it is proportional to the |
|
| analog signal. |
Sequence | Contact Distributor | Connect contact signals between function blocks |
Operation |
| in a 1:1 connection. |
|
|
|
| Constant Comparator | Compares up to eight sets of analog signals and |
| (See note 1.) | constants, and outputs the comparison results as |
|
| contacts. |
| Variable Comparator | Compares up to eight pairs of analog signals, |
| (See note 1.) | and outputs the comparison results as contacts. |
| Timer (See note 1.) | |
|
| values and reached values. Can also output the |
|
| present value. |
|
|
|
| ON/OFF Timer | Timer for performing |
| (See note 1.) | ON and OFF times. |
| Clock Pulse | Outputs a clock pulse at the setting time interval |
| (See note 1.) | for a single operation cycle. |
| Counter (See note 1.) | |
|
| values and arrival values. Can also output the |
|
| current value. |
|
|
|
| Internal Switch | Temporary storage contact for accepting relays in |
| (See note 1.) | the Step Ladder Program block. |
|
| Note: (One internal switch is already allocated |
|
| as “temporary storage” in |
|
| Tool.) |
|
|
|
| Level Check | Checks an analog input for 8 levels and outputs |
| (See note 1.) | a contact corresponding to the level. The level |
|
| number is also output as an analog value at the |
|
| same time. |
|
|
|
Contact Type | ON/OFF Valve Manipu- | Manipulates and monitors ON/OFF valves with |
Control Target | lator | open/close limit switches. |
| Motor Manipulator | Manipulates and monitors motor operation. |
|
|
|
| Reversible Motor Manip- | Manipulates and monitors reversible motor |
| ulator | operation. |
|
|
|
| Motor Opening Manipu- | Inputs a target opening, and manipulates an |
| lator | electric |
| Switch Meter | Manipulates and monitors multiple (up to 8) |
| (See note 2.) | devices such as ON/OFF valves, motors, or |
|
| pumps. |
