SAFETY PRECAUTIONS

(Read these precautions before using.)

When using Mitsubishi equipment, thoroughly read this manual and the associated manuals introduced in this manual. Also pay careful attention to safety and handle the module properly.

The precautions given in this manual are concerned with this product. Refer to the user's manual of the network system to use for a description of the network system safety precautions.

These SAFETY PRECAUTIONS classify the safety precautions into two categories: "DANGER" and

"CAUTION".

! DANGER

CAUTION

!

Indicates that incorrect handling may cause hazardous conditions, resulting in death or severe injury.

Indicates that incorrect handling may cause hazardous conditions, resulting in medium or slight personal injury or physical damage.

Depending on circumstances, procedures indicated by ^! CAUTION may also be linked to serious results.

In any case, it is important to follow the directions for usage.

Store this manual in a safe place so that you can take it out and read it whenever necessary. Always forward it to the end user.

[DESIGN PRECAUTIONS]

! DANGER

If a communication error occurs in the network, the error station (MELSEC-ST system) shows the following behavior.All outputs turn OFF. (In the MELSEC-ST system, the output status at the time of error can be set to clear/hold/preset by using user parameters of each slice module.

As “clear” is set by default, the outputs turn OFF when an error occurs. In the case where the system operates safely with the output set to “hold” or “preset”, change the parameter

settings.)Create in the program an interlock circuit that will ensure the system operates safely based on the communication status information.Failure to do so may cause an accident due to mis-output or malfunction.

Create an external fail safe circuit that will ensure the MELSEC-ST system operates safely, even when the external power supply or the system fails.

Accident may occur due to output error or malfunctioning.

(1) The status of output changes depending on the setting of various functions that control the output. Take sufficient caution when setting for those functions.

(2) Normal output may not be obtained due to malfunctions of output elements or the internal circuits.Configure a circuit to monitor signals which may lead to a serious accident.

(4)

[DESIGN PRECAUTIONS]

! CAUTION

Make sure to initialize the network system after changing parameters of the MELSEC-ST system or the network system. If unchanged data remain in the network system, this may cause malfunctions.

Do not install the control wires or communication cables together with the main circuit or power wires. Keep a distance of 100 mm (3.94 inch) or more between them. Not doing so could result in malfunctions due to noise.

(3) Functions for communication with master station

Using the following functions, the head module can communicate with the master station.

(a) I/O data size selection

The head module uses input data (head module master station) and output data (master station head module) to communicate with the master station.

By selecting the maximum input/output points appropriate for the MELSEC- ST system configuration on the head module, the input/output data

communicated with the master station can be adjusted to the optimum size.

(Refer to Section 3.2.1, 3.2.2.)

Also, the maximum I/O points can be set to a slightly larger size for future expansion of the MELSEC-ST system. (Refer to Section 6.1.1.)

(b) Supporting the global control functions

The head module supports the global control functions.

Using the commands (SYNC, UNSYNC, FREEZE, UNFREEZE) sent by the master station, the refresh of the head module I/O data can be controlled from the master station. (Refer to Section 4.2.2.)

(c) Extended diagnostic information notification function

When an error occurs in a slice module, the master station can be notified of the error as extended diagnostic information.

When the slice module is restored to normal, the master station is also notified of it. (Refer to Section 4.2.3.)

(d) Swapping of I/O data or extended diagnostic information bytes

When I/O data are sent to or received from the master station or when extended diagnostic information is sent to the master station, their high and low bytes can be swapped in word units.

This function eliminates the need for a high/low byte swapping program on the master station side, simplifying the program. (Refer to Section 4.2.4.)
