Safety Instructions

Safety Instructions for design process

 Please install a protection circuit on the exterior of PLC so that the

whole system may operate safely regardless of failures from external power or PLC. Any abnormal output or operation from PLC

may cause serious problems to safety in whole system.

- Install protection units on the exterior of PLC like an interlock circuit that deals with opposite operations such as

emergency stop,

protection circuit, and forward/reverse rotation or install an interlock circuit that deals with high/low limit under its position controls.

- If any system error (watch-dog timer error, module installation error, etc.) is detected during CPU operation in PLC, all output signals are designed to be turned off and stopped for safety. However, there are cases when output signals remain active due to device failures in Relay and TR which can’t be detected

. Thus, you are

recommended to install an addition circuit to monitor the output status for those critical outputs which may cause significant problems.

 Never overload more than rated current of output module nor

allow to have a short circuit. Over current for a long period time may cause a fire .

 Never let the external power of the output circuit to be on earlier

than PLC power, which may cause accidents from abnormal output or

operation.



Please install interlock circuits in the sequence program for safe

operations in the system when exchange data with PLC or modify operation modes using a computer or other external equipments

Read specific instructions thoroughly when conducting control operations with PLC.

1) 64 I/O points are assigned to each slot regardless of module.

2) 1024 (64*16) I/O points are assigned to each base. Namely no. 1 base’s start number is P00640. (Refer to

2.3.2)

3) The example of I/O assignment of 12 slot base is as follows.

0 1 2 3 4 5 6 7 8 9 10

1) The point changes according to each module equipped at the slot.

2) If there is no module, designated point is assigned.

3) The slot not designated by I/O parameter is assigned according to the equipped module automatically. (8 points module is assigned as 16 points.)

4) The empty slot not designated by I/O parameter is assigned as 16 points.

5) It is possible to set the points without designation of module.

6) 16 points is assigned at the slot where special and communication module is equipped.

7) The example of assignment of I/O point for 12 sl ot base is as foll ows.

IO number allocation of

extension base

• IO number start value o f each base is determined by base number set in extension drive module. (1~31)

• IO number in base is fixed as 64 per slot.

Each slot is allocated 64 points regardless of module equipment and ty pe

• Special module doe sn’t use IO number to control unlike digital IO module. It uses U device and dedicated function block

• IO number allo cation of 12 slot base is as follows.

IO number of basic

base

• IO number doesn’t have meaning in basic base because only communication module can be equipped.

• Thought basic base doesn’t use IO number, it is allocated same with 12 slot extension base.

•

B ase number of basic base is 0 and it is positioned at the first o f IO number.

Note

(1) Redundant basic base is fix ed as ‘0’. In the e xtension base, there is switch to set base number.

(2) Redundant CPU can b e installed at basi c base.

(3) Redundant CPU is CPU module o ccupying two slots. (4) In order to start, module type set by IO parameter should be sa me with real equipped module type.

Additional information of some items in [T able 6.2.1] is as follows.

Chapter 6 Communication Parameter

6-5

(1) Communication type

Check the Cnet I/F module and set the parameter about each channel accurately. If communica tion ty pe set by parameter is different with channel ty pe of real co mmunicati on module, normal communication is impossible because CPU recognizes th e channel ty pe of real communication module.

(a) Parity bit

The Cnet I/F module defines three parity bit. Each parity bit has the following meaning like [Table 6.2.2].

Parity Meaning reference None Not use parity bit

Even If the number of 1 is even in the one byte, it sends 0 at the parity bit.

Odd If the number of 1 is odd in the one byte, it sends 0 at the parity bit.

[Table 6.2.2] Parity content

(b) Dedicated service driver

The user can select the operation mode about each channel of Cnet I/F module by using the driver selection item. Each channel of Cnet I/F module operates as server or client, each channel operates independently.

Type and meaning of operation mode for each channel is as following [Table 6.2.3].

6.6 How to set the Parameter according to Service

6.6.1 Exclusive Service

Through this exclusive service function built-in Cnet I/F module, information and data of PLC can be read or written in PC and associated devices without additional programming in PLC. It operates as a server in communication network and responds to memory Read/Write request conforming to exclusive XGT protocol in external devices or PC, or conforming to Modbus protocol. In order to use the exclusive service, select the operation mode for the channel used for server among Cnet channels 1 and 2 when setting basic communication. It supports XGT server and Modbus server which respond to both RTU and ASCII format. Since Cnet I/F module respective channel operates separately, it can not be set to other type of server. Refer to exclusive service related items in “Diagnosis and error code” for details on check and diagnosis of normal operation of the exclusive service.

(1) XGT server

During the exclusive service, all the frames used in XGT server shall not exceed 256 Bytes. And the characters used in all the frames are of ASCII code. If used as multi-drop, up to 32 stations can be connected with. Be careful not to set the duplicated station number to the identical network when setting station number. Communication speed/stop bit/parity bit/data bit of all the Cnet I/F modules shall be surely identical on the network if used as multi-drop. XGT server supports only the memory Read/Write function of the Exclusive XGT protocol.

(2) Modbus server

It is used when the correspondent device to communicate with operates as Modbus Client. It supports both Modbus’s

ASCII Mode and RTU Mode, whi ch can be specified in the active mode of standard settings window.
