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.

These precautions apply only to Mitsubishi equipment. Refer to the CPU module user’s manual for a description of the PC system safety precautions.

These  SAFETY PRECAUTIONS  classify the safety precautions into two categories: “DANGER” and “CAUTION”.



DANGER

Procedures which may lead to a dangerous condition and cause death or serious injury if not carried out properly.



CAUTION

Procedures which may lead to a dangerous condition and cause superficial to medium injury, or physical damage only, if not carried out properly.

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



When controlling a PLC by connecting to another station via PROFIBUS for the purpose of changing the data, changing the program, or changing operation status (status control), an interlock circuit must be configured in the sequence program so that the entire system will always operate safely. If a remote PLC is a controlled in the manner indicated above by another station, the system may fail to respond immediately even if trouble occurs at the remote PLC due to data communication error. In addition to configuring the interlock circuit in the sequence program, determine the action to be taken by the system at the occurrence of the data communication error with regard to the processing between the other stations and PLC CPU.



CAUTION



When the PROFIBUS cable is laid, do not lay it close to main circuits or power lines. They should be installed 100mm(3.9inch) or more from each other. Not doing so could result in noise that would cause malfunction.

[INSTALLATION PRECAUTIONS]



CAUTION

Use the module in the environment given in the general specifications of the CPU module’s User’s Manual.

Using the module outside the range of the general specifications may result in electric shock, fire or malfunction, or may damage or degrade the module.

Insert the tabs at the bottom of the module into the mounting holes in the base unit.

(The AnS series module shall be fastened by screws in the base unit at the specified torque.) Not installing the module correctly could result in malfunction, breakdowns or pieces of the product falling.

Do not touch the conductive area or electric parts of the module.

Doing so may cause module malfunction or breakdowns.

Tighten the screws with the specified torque. If the screws are loose, it could result in falling, breaks or

malfunction of the module. If the screws are too tight, it could result in falling, breaks or malfunction due to damage of the screws or the module.

[WIRING PRECAUTIONS]



CAUTION

Switch all phases of the external power supply of the PC system off before connecting the PROFIBUS cable.

Not doing so could cause failure or malfunction of the module.

Be careful not to let foreign matter such as filings or wire chips get inside the module. These can cause fire,

breakdowns and malfunction.

The PROFIBUS cable which is connected to the module must be protected with a duct or secured in position

with clamps. Unless the cable is thus protected or secured, the module or the cable could be damaged when the cable swings, moves or it is strained with careless pulls, or it could cause malfunction when the cable contacts with any undesirable objects.

When disconnecting the PROFIBUS cable from the module, do not pull by holding the cable section. To

disconnect the cable, make sure to hold the connector which is coupled with the module. Do not attempt to pull the cable to disconnect it from the module. It could damage the module or the cable, or cause malfunction due to a poor contact of the cable.

[STARTING AND MAINTENANCE PRECAUTIONS]



DANGER

Switch all phases of the external power supply off before cleaning. Not doing so could cause electric shock.



CAUTION

Never disassemble or modify the module.

This may cause breakdowns, malfunction, injury and/or fire.

Switch all phases of the external power supply off before mounting or removing the module. If you do not

switch off the external power supply, it will cause breakdowns or malfunction of the module.

[OPERATING PRECAUTIONS]



DANGER

Do not write data into the "unused area" of the buffer memory of this modules. Also, do not output the

"unused" signal as the output signal to this module from the PC CPU. Writing data into the "unused area" or outputting an "unused" signal may cause system malfunctions in the PC.



CAUTION

The online operations conducted for the CPU module being operated (especially when changing data or

operation status), shall be conducted after the manual has been carefully read and a sufficient check of safety has been conducted. Operation mistakes could cause breakdowns to or malfunction of the module.

[DISPOSAL PRECAUTIONS]

The AJ71PB96F/A1SJ71PB96F general characteristics are explained below.

(1) Operates as a client or server in the PROFUBUS-FMS network.

(a) When operating as a client:

•

The partner station variable can be read/written using the I/O signal X/Y and buffer memory.

•

The partner station status and ID information can be read using the I/O signal X/Y and the buffer memory.

•

The non-confirmation type service can be transmitted using the I/O signal X/Y and the buffer memory.

(b) When operating as a server:

•

The PC CPU device can be read/written to from the client. (without sequence program)

•

The sequence program, parameters, comments, device memory, and buffer memory can be uploaded/downloaded from the client. (without sequence program)

•

The sequence program can be run, stopped, or paused from the client. (without sequence program)

•

The non-confirmation type service can be received using the I/O signal X/Y and the buffer memory.

The service that can actually be used depends on the connection type and partner station installed service, etc. For details refer to Item 4-4.

(2) Operates as a master station in the PROFIBUS-FMS network.

In addition, the same operation as that of a slave station can be done using slave emulation.

(3) When used in combination with MELSECNET (II), MELSECNET/B or MELSECNET/10 the

client can access from the MELSECNET (II), MELSECNET/B or MELSECNET/10 station. For details refer to Item 2.3.2

(4) The client can read/set the OD (Object Dictionary), CRL (Connection Relationship List), and

bus parameter via the PROFIBUS-FMS network.

(5) The utility software package SW0IX-PROFPE is used when the OD, CRL, and bus

parameters are set in the AJ71PB96F/A1SJ71PB96F.

Remark

Following is an explanation of the terminology used for bus parameters.

Tsdr: Station Delay Time as Responder Bit Time: The time required to transmit 1 bit = 1/baud rate Slot Time: The maximum time that the requester must wait for a response from the

responder. Max Tsdr < Slot Time

Min Tsdr: The minimum time required for the responder to respond.

Quiet Time < Min Tsdr, Setup Time < Min Tsdr Max Tsdr: The maximum time required for the responder to respond. Quiet Time: The time required for the repeater to switch from the transmission mode to the

receive mode. Setup Time: The time required for the requester to switch from the transmission mode to

the receive mode. Target Rotation Time: If the actual token rotation time becomes larger than this time, cyclic

communication will no longer be possible. GAP Update Factor: This shows how many times the station information can be updated for 1 token

rotation.

Station information update interval = G x Target Rotation Time HSA: Highest Station Address. The highest address of the stations connected to the

network. Max Retry Limit: The maximum number of transmission retries when data transmission fails.

4. FUNCTIONS MELSEC-A

4.3 Communication Relationship

In PROFIBUS, all of the connection information must be written in CRL (Communication Relationship List) as communication relationships (hereafter abbreviated as communication). Communication contains connection oriented communication that is required for establishing logical circuits before communication and connection less list communication that does not have data communication certainty when establishing logical circuits before communication is not required. In addition, it also contains FMS communication and FMA7 communications.

The following communication types are prescribed for FMS communication.

MMAC (Master to Master Acyclic Connection) MSAC (Master to Slave Acyclic Connection) MSAC_SI (Master to Slave Acyclic Connection/Slave Initiative) MSCY (Master to Slave Cyclic Connection) MSCY_SI (Master to Slave Cyclic Connection/Slave Initiative) BRCT (Broadcast) MULT (Multicast)

In addition, the communications other than BRCT and MULT have the following attributes:

/D : Defined connection /I : Request open connection /O : Responder open connection

However, MSxx's /O connections are not allowed. (PROFIBUS standard) Of these, BRCT and MULT are connectionless communications and the others are connection oriented communications.

All FMA7 communications are connection oriented. In AJ71PB96F/A1SJ71PB96F, the above all communications are enable to use by using the software

package. In AJ71PB96F/A1SJ71PB96F, when the following conditions are met the maximum number of

communications including FMA7 communications can be set to 32. In other cases the maximum number of communications that can be set is 16.

(1) Communication type conditions

Communications are divided into the following two types.

Category I

MMAC (Master to Master Acyclic Connection) MSAC (Master to Slave Acyclic Connection) MSCA_SI (Master to Slave Acyclic Connection/Slave Initiative) SMA7 communication

Category II

MSCY (Master to Slave Cyclic Communication) MSCY_SI (Master to Slave Cyclic Communication/Slave Initiative) BRCT (Broadcast) MULT (Multicast)

The number of communications must satisfy the following formula. Category I number of communications × 2 + Category II number of communications ≤ 32

(2) PDU size conditions

All of the PDU sizes for all communications shall be 200 or less.

Remark

Following is an explanation of the terminology used with CRL. (a) Connection Type

•

MMAC: Master to Master Acyclic Connection. Service requests can be sent from both stations.

•

MSAC: Master to Slave Acyclic Connection. Service requests can only be sent from the master station.

•

MSAC_SI: Master to Slave Acyclic Connection. (Service requests can be sent from the slave station.) In addition to the MSAC communication format InformationReport and UnsolicitedStatus can be sent from the slave station.

•

MSCY: Master to Slave Cyclic Connection. Service requests can only be sent from the master station.

•

MSCY_SI: Master to Slave Cyclic Connection: (Service requests can also be made from the slave station.) In addition to the MSCY communication format InformationReport and UnsolicitedStatus can be sent from the slave station.

•

BRCT: Broadcast communication (connectionless). InformationReport and UnsolicitedStatus can be sent from master stations to all stations.

•

MULT: Multicast communication (connectionless). InformationReport and UnsolicitedStatus can be sent to multiple stations within a certain group. The group consists of stations with the same Remote LSAP.

(b) Connection Attribute

•

/D: Define Connection. This attribute securely fixes the connection partner.

•

/I: Requester Open Connection. When establishing a connection multiple partner stations are connected to the LSAP of the receiving side. (However, the connections are not made at the same time.)

•

/O: Responder Open Connection. When establishing a connection multiple partner stations are connected to the LSAP of the receiving side. (However, the connections are not made at the same time.)

to which the connection is established is monitored to see if it is operating correctly.

(d) Max SCC: Max Send Confirmed request Counter. The number of maximum confirmed

services that can be sent by the confirmed service request side (client) before the response to the previously sent service is received.

(e) Max RCC: Max Receive Confirmed request Counter. The number of maximum confirmed

services that can be received by the confirmed service request reception side (server) before the previously sent service is returned.

(f) Max SAC: Max Send Acknowledged request Counter. This is the number of unconfirmed

services that can be sent by the unconfirmed service request sending side before the ACK of the previously sent service is received.

(g) Max RAC: Max Received Acknowledged request Counter. This is the number of

unconfirmed services that can be received by the unconfirmed services receiving side before the response to the previously sent service is returned.

(h) Max send PDU(H): This is the maximum size of a packet sent by high priority. Acyclic

communication data is sent by high priority.
