HITACHI S10VE Programmable Controller

HITACHI S10VE Programmable Controller

Usage Notes

￭ Installation

The programmable controller employs electronic circuit and processor technologies. Note the following in particular:

● When constructing a system, make sure that conditions including the maximum rating, operating power supply voltage range, heat dissipation characteristics, and installation conditions are within the guaranteed operating range described in this manual. Hitachi bears no responsibility for failures or accidents that arise from use of the product outside the guaranteed range.

Even when using the product within the guaranteed range, you must consider the predicted failure rate and failure mode of the product. You can then implement system measures such as making the system failsafe so that operation of the Hitachi product will not cause personal injury, fire, and other consequential damage.

The Programmable Controllers ( ((PCs^{#})) ) in which the CPU unit and PI/O units are installed are neither fireproof, dustproof, nor waterproof. Install the PCs in steel cabinets that are fireproof, dustproof, and waterproof (see Figure 1-1).

#: PCs means the programmable controllers in their entirety including the CPU unit and PI/O units.

● Use the S10VE in an environment that is within the specifications explained in Chapter 3. To ensure long-term stable operation, we recommend that you use the product at room temperature and normal relative humidity (15 to 35°C and 45 to 85% RH). Using the product in a high-temperature or high-humidity environment or an environment where the temperature varies widely over the course of a day leads to a reduced service life.

￭ Output module

You must provide a short-circuit protection fuse in the load power supply circuit of the output module. Use fuses with the correct load rating. Using the wrong fuse might result in damage to the PCB or housing if the load shortcircuits.

￭ Grounding

● Panel grounding specifications

The PCs panel that incorporates the S10VE must be welded to the steel frame of a building that provides at least class D grounding with the ground resistance of 100Ω or less.

Conditions for grounding to the steel frame of a building

- The steel frame is welded together

- The grounding between the earth and the steel frame meets the criteria for class D

If this is not achievable, ground the PCs panel by connecting it to a grounding rod driven into the earth. This provides a low grounding resistance that prevents surrounding noise from entering the PCs.

￭ Noise

Do not install the S10VE in or near a panel to which a high-voltage device (such as an inverter) is mounted. If this is unavoidable, use a shielding plate to shield the CPU unit, PI/O units, and cabling from electromagnetic and electrostatic induction.

￭ Emergency stop circuit

A partial failure can affect the entire system. Provide an emergency stop circuit as an external circuit. Do not incorporate the emergency stop circuit into programs run on the programmable controller.

￭ Disassembling modules

Do not disassemble the modules.

￭ Removing/inserting modules

You must turn off the power before removing or inserting a module. To prevent module damage due to static electricity, discharge any static electricity from your body before touching the equipment.

￭ Installation of new equipment

When peripheral equipment is added or replaced, check the following aspects of the power supply and grounding:

●Power supply

Inspect the power supply voltage and waveform.

- Has the voltage dropped?

- Is there any noise in the power cable?

1. Usage Notes

● Grounding

- Make sure that the S10VE does not share its ground cable with other equipment.

- Make sure that no power or lead cables are positioned too closely to a signal cable (such as a remote I/O cable).

2. Overview

2.1 Overview of the system

The S10VE is a programmable controller suited for a wide range of applications from simple condition control to complex arithmetic control. It is capable of simultaneously executing ladder logic, HI-FLOW, and C languages.

2.2 System configuration

2.2.1 Example system configuration

Figure 2-1 shows an example configuration of an S10VE system.

An S10VE system is made up of a CPU unit, PI/O units, and peripherals.

By installing option modules (OD.RING, D.NET, J.NET, FL.NET, ET.NET) in the CPU unit, an S10VE system can connect to an optical communication network and various other optional networks.

By installing a remote I/O interface module (hereafter RI/O-IF module) in the CPU unit, the system can connect to HSC-1000 and HSC-2100 PI/O units using remote I/O lines. A given system can incorporate both HSC-1000 and HSC-2100 PI/O units.

2.2.2 CPU unit configuration

An S10VE system is made up of a mount base, power supply module, RI/O-IF module, CPU module, and PI/O modules. The mount base incorporates one PS slot (a dedicated slot for the power supply module), one IF slot (a dedicated slot for the RI/O-IF module), one CPU slot (a dedicated slot for the CPU module), and seven I/O slots. The power supply module and CPU module are mandatory components of an S10VE system. Installation of an RI/O-IF module, option modules, and PI/O modules is optional.
