Programmable logic controllers are open-type devices that must be installed and used

within conductive control boxes.

Please use the HCA2Series programmable logic controllers while installed in conductive

shielded control boxes.

Please secure the control box lid to the control box (for conduction).

Installation within a control box greatly affects the safety of the system and aids in

shielding noise from the programmable logic controller.

1.2 Rules of Expansion

The maximum I/O for an HCA2system is 128 I/O points and 8 special function blocks.

The HCA2 Series can be expanded as follows when used independently.

- 2 special function blocks

- 1 special function block and up to 16 I/O points

- Up to 32 I/O points

An AC powered HCA2 can be expanded by 8 special function blocks when used in

conjunction with an HCA5 extension unit (2+6).

•If a DC powered main unit is used with a power supply of less than 24VDC -15% (20.4V

DC or less), then it cannot be fully expanded by using special function blocks or powered

extension units.

It can accommodate a maximum of an additional 32 I/O points.

HCFA Corporation Limited

•If an HCA2 expansion board is being used, it does not alter the rules of expansion

outlined above, as it utilizes special M coils for its operation and therefore does not

contribute to the maximum 128 I/O point count. Only one special function board can be

used at any time.

See section 3.8 for more details.

1.3 Back up Data

1.3.1 EEPROM backup

Data includes the Program, Comment, File Registers (D1000 ~ D7999), and parameter

data.

This will be stored as long as the EEPROM is not damaged. HCFA Electric has

guaranteed a life cycle time of 10,000 writes to the EEPROM memory. Users may

experience operational writes to the EEPROM in excess of 10,000; however, due to

temperature effects a quantitative estimation cannot be given.

When saving the device status in the EEPROM, the electric power of the PLC's built-in

capacitor is used.

If the PLC has been powered on for five minutes or more, the following device data will be

saved in the EEPROM at power down: S0 ~ S127, M384 ~ M511, C16 ~ C31, C235

~C255, and D128 ~ D255.

When the EEPROM keep device status cannot be correctly saved to the EEPROM by

shortage of electric charge, at the next power-on the status of the device will be that which

saved to the EEPROM at the last save.

1.3.2 Capacitor backup

The capacitor backed memory includes M512 ~ M1535, S128 ~ S999, T246 ~ T255, C32

~ C199, C220 ~ C234, D256 ~ D7999 and the RTC.

The capacitor backed memory will retain data for a maximum of 10 days (Ambient

temperature: 25 °C), and requires 30 minutes to recharge upon power up.

Note: The HCA2 does not have battery backup, if a system requires backup of more than

10 days (Ambient temperature: 25 °C), a peripheral backup power source must be

provided.

1.3.3 Initialize Latched (Keep) Devices

•When using non-latched devices

To use the latched devices as the non-latched devices, reset the latched devices by an

initial pulse (M8002) in program.

•When using capacitor latched (keep) devices

If the voltage of a capacitor drops, the capacitor keep device status may be stored

incorrectly. Therefore, when using the PLC after it has been powered off for more than 10

HCFA Corporation Limited

days (Ambient temperature: 25 °C), re-set up the required devices and the current time

after initializing capacitor latched (keep) devices before selecting RUN.

Initialization method

Latched (keep) devices can be initialized in the PLC memory by using peripheral

equipment, and the special auxiliary relay M8032, or executing the ZRST instruction. The

two major methods are described below.

•Latch memory all clear by special auxiliary relay (M8032)

When M8032 is turned ON, all latched (keep) devices (including reset coils of timers and

counters) are cleared. M8032 can be turned ON and OFF using the forced ON/OFF

operation from peripheral equipment or within the sequence program. Note that latched

devices cannot be turned ON while M8032 is ON. When turning ON M8032 within the

sequence program, note that latched devices are cleared during END processing after

M8032 is turned ON.

Program example: This program clears all latched devices.

•Reset of device by ZRST (zone reset) instruction

The ZRST instruction can clear multiple devices at once. (Because a limited device range

can be specified for the ZRST instruction, only part of the latched (keep) devices can be

cleared at a time.)

However, initialization method by the ZRST

instruction for capacitor backed timer and

counter devices

(T246 ~ T255, C32 ~ C199, C220 ~ C234)

does not reset the associated coil devices.

In order to initialize the associated coil

devices, execute the RST instruction for

the coil devices being used in the user

program as shown in the example program

on the left.

2. Terminal layouts

The following selection of terminal layouts are taken from the HCA2product range.

Note: All layouts are schematic only and are intended to aid the creation of wiring

diagrams.

3. Installation Notes

The installation of HCA2products has been designed to be safe and easy. When the

products associated with this manual are used as a system or individually, they must be

installed in a suitable enclosure. The enclosure should be selected and installed in

accordance to the local and national standards.
