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 PLC 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 a communication error occurs in the PROFIBUS network, the status of the faulty station is as follows. Configure an interlock circuit in the sequence program using the communication status information (input X1, buffer memory 2040 to 2079) so that the system can operate safely. Erroneous outputs and mis-operation could cause accidents. (1) The input data of the master station maintains the data before abnormality of the communication. (2) When the master station is down, the output state of each slave station will be in accordance with the

parameter settings.

(3) When any slave station is down, the output state of other slave stations will be in accordance with the

parameter settings of the master station.

If a stop error occurs in the CPU module, the communication status is as described below. (1) Communication with the slave station is stopped. (2) For the input data received from the slave station, the values at CPU module stop error occurrence are

held.

(3) The output data sent from the AJ71PB92D/A1SJ71PB92D to the slave station are cleared.

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 malfunctioning.

Page 4

[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 malfunctioning, or may damage or degrade the module.

Insert the tabs at the bottom of the module into the mounting holes in the base unit before installing the module. (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 malfunctioning, breakdowns or pieces of the product falling

Tighten the fixing screws of the PROFIBUS cable with the specified torque. If the screws are loose, it could result in malfunction of the module.

Do not touch the conductive area or electric parts of the module. Doing so may cause module malfunctioning or breakdowns.

[WIRING PRECAUTIONS]

CAUTION

Switch all phases of the external power supply of the PLC system off before connecting the PROFIBUS cable. Not doing so could cause failure or malfunctioning 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 malfunctioning.

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.

Page 5

CAUTION

Never disassemble or modify the module. This may cause breakdowns, malfunctioning, 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.

Set the ON/OFF select switch of the terminal resistor before the operation. If the setting is switched during the operation, network error may occur, or error detection may not be performed by error.

Before handling the module, always touch grounded metal, etc. to discharge static electricity from the human body. Failure to do so can cause the module to fail or malfunction.

[OPERATING PRECAUTIONS]

DANGER

Do not write data into the "not usable" of the buffer memory of special function modules. Also, do not output the "not usable" signal as the output signal to a special function module from the PLC CPU. Writing data into the "not usable area" or outputting an "not usable" signal may cause system malfunctions in the PLC.

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]

CAUTION

When disposing of this product, treat it as industrial waste.

1.2 AJ71PB92D/A1SJ71PB92D Features

(1) Operates as a PROFIBUS-DP master (class 1) station. (2) Makes possible the exchange of input and output data to and from the slave station

without the need to be aware of the PROFIBUS-DP protocol by using I/O signals X/Y and the buffer memory.

(3) Supports 3M, 6M, 12M [bps] network communication speeds in addition to the 9.6k, 19.2k,

93.75k, 187.5k, 500k, and 1.5M [bps] supported by the AJ71PB92D/A1SJ71PB92D. These

can be selected using a configurator. (4) Station Nos. from 0 to 125 can be set using the configurator. (5) Trouble information can be read from the slave station using the I/O signal X/Y and the

buffer memory. (6) The global control function makes it possible to maintain all slave I/O at the same time. In

addition, this can also be canceled. (7) The module contains a self-diagnosis function that can be used to test the hardware such

as the internal memory.

later) or A1SJ71PB92D (E or later). When A1SJ71PB92D (software version D or earlier) is used, write is disabled and the max. data length is 32 bytes each for input and output.

(2) Precautions for using the parameters preset for extended service mode to operate the

module in normal service mode.

The following table gives the operating conditions (conditions per one slave station) for the time when the parameters preset for the extended service mode are used to operate the AJ71PB92D/A1SJ71PB92D preset for the normal service mode/extended service mode.

(3) In either of the following cases, the AJ71PB92D/A1SJ71PB92D buffer memory must be

accessed by a sequence program when the module ready signal X1D of the AJ71PB92D/A1SJ71PB92D is ON.

• The operation mode is changed using Y11/X11 in the sequence program.

• Parameter setting is made with ProfiMap connected to other than the RS-232C port of

the AJ71PB92D/A1SJ71PB92D. (For example, parameter setting is made with ProfiMap

connected to the RS-422/RS-232 connector of the CPU module.) If the buffer memory is accessed with the X1D status ignored, the CPU module may detect the "SP UNIT DOWN" error, stopping the sequence operation.

Page 17

2. SYSTEM CONFIGURATION MELSEC-A

2-6

(4) Do not make parameter setting via buffer memory and parameter setting from the RS-

232C port of the AJ71PB92D/A1SJ71PB92D at the same time.

If they are made simultaneously, ProfiMap which started parameter write earlier wins the parameter write right after the operation mode is changed to the parameter setting mode, and the other ProfiMap cannot perform parameter write and detects an error. This status will be automatically cleared 15 seconds after completion of parameter write if parameter write via the CPU module is valid, or 3 seconds after completion of parameter write if parameter write from RS-232C is valid.

(5) Do not make simultaneous access to the AJ71PB92D/A1SJ71PB92D from multiple

ProfiMap's.

If such access is made, the AJ71PB92D/A1SJ71PB92D may not be accessed properly.

(6) If remote parameter setting is performed from MELSEC ProfiMap to the

AJ71PB92D/A1SJ71PB92D which is making data exchange, note that PROFIBUS data

exchange will stop during parameter setting.

(7) In a system where remote parameter setting is made from MELSEC ProfiMap, do not

execute the mode changing function using the program.

If the mode changing function is executed in the program, an interlock with the remote parameter setting is not provided and therefore the mode may not be changed.

Point

In configurations that use multiple master stations (multimaster configuration), when reconnecting a cable after disconnecting a PROFIBUS cable for 1 master that is exchanging data at a low baud rate, the communications of the master for which the cable is not disconnected could stop and the slave output could be turned off. To prevent this, the master PROFIBUS cable must be secured with a screw.

In addition, there is a high possibility that the above phenomena can be avoided if care is taken with the following points when configuring a system.

(1) Set the slave watchdog timer setting value to larger than (T

r × G)/BR. However, TTr : Target token rotation time (Unit: Bit Time) G : Gap update factor BR : Baud rate (Unit: bps)

(2) Use a high baud rate. (3) The HSA (Highest Station Address) value is made to match the maximum station No. that is

actually connected.

3.3.3 Number of connectable slaves

Please calculate the number of the slave which can be connected under the following (1) and (2) conditions.

(1) Restrictions on maximum data length of slave station error

information

The maximum data length of the slave station error information that the AJ71PB92D/A1SJ71PB92D can receive varies with the minimum station number and maximum station number of the slave stations set in the parameters, and can be calculated using the following expression.

Maximum data length of acceptable error information [bytes] = Min

12600 N - 10

, 244

N = Min((a - b + 1) 5, 300) a: Maximum station number of slave station

b: Minimum station number of slave station

: Min(a, b) = A or B, whichever is smaller

If the maximum data length (Max_Diag_Data_Len) of the error information described in the GSD file of a slave station is greater than the value calculated by the above expression, normal communication may not be made with that slave station. If normal communication cannot be made, try the following methods: (a) Set the station numbers of the slave stations with no unused numbers in

between.

(b) Make setting on the slave station side to shorten the maximum data length of

the error information. (If possible)

stations per module.

(2) Restrictions on parameter data length of slav e stati on

The parameter size which can be set in AJ71PB92D/A1SJ71PB92D should meet the following formula. Note that the system construction which does not meet the following formula causes the error of 1302

5 +

i = 1

n = number of slave stations (number of parameter blocks of each slave station) = sum total of the numbers of parameter blocks calculated by each slave station

Page 26

3. SPECIFICATIONS MELSEC-A

3-9

The number of parameter blocks for each station is decided by the parameter size of the station as follows.

Parameter size of each slave station

Number of blocks of each

slave station 246 bytes or less 1 block 247 to 480 bytes 4 blocks 481 to 720 bytes 5 blocks 721 to 762 bytes 6 blocks

Calculate the parameter size of each slave station using the following formula. Parameter size of each slave station = 31 + (User_Param data length)

+ (configuration data length) +

(a) User_Param data length

The value of User_Prm_Data usage on the screen displayed when Select Modules is selected on the slave station setting screen of GX ConfiguratorDP.

(b) Configuration data length

The value differs depending on the slave station type as shown below.

1) Module type slave station Sum of the number of Module set values, which are described in the GSD file of the slave station, of the modules registered to the [slot] Installed Module list.

2) Block type slave station Number of Module set values described in the GSD file of the slave station.

(Example) GSD file description

= 2 : When the slave station has only input or output = 4 : When the slave station has both input and output

(example) When the system is constructed using only the stave stations with 520 bytes parameter, AJ71PB92D/A1SJ71PB92D can be connected up to the following number of the slave stations. When the parameter size is 520 bytes, the number of the parameter block is five.

5 + (5

n) 128 : n = number of slaves

n = 24.6

128 - 5

n = 24

The calculation mentioned above tells that AJ71PB92D/A1SJ71PB92D can be connected up to 24 slave stations. Therefore, when 25 slave stations or more are set by the parameter, AJ71PB92D/A1SJ71PB92D detects the error of 1302

4. FUNCTIONS

4.1 Functions for Exchanging with Slaves

The main function in the AJ71PB92D/A1SJ71BP92D is for exchanging I/O data with slave stations connected to the PROFIBUS-DP network. The method used for this exchange is to read/write the I/O image in the buffer memory using FROM/TO instructions. A schematic drawing of this exchange function is as follows.

4.1.2 Global control functions

Global control contains the four functions of SYNC, UNSYNC, FREEZE, and UNFREEZE, which are functions that are used to maintain/cancel slave I/O for which multicast communication is conducted at the same time. The slaves that execute the global control function are those located in one or more groups of the eight groups. The group No. of the group containing the slaves is set by the configurator. In the AJ71PB92D/A1SJ71PB92D the group can be arbitrary specified and the global control commands transmitted using multicast communication. This makes is possible to select a slave and conduct global control.

(b) Extended service mode (MODE switch : No. E)

This is the area that stores the input data from the slave station. In this area, the data length (in byte units) for each station is assigned in variable length according to the parameter file set in the configurator software package. The data length can be set in the range of 0 to 244 bytes. Number of stations that can be set will vary in the range of 1 to 60, depending on the specified data length. For example, seven stations can be set if the data length for each station is 244 bytes, and 60 stations if the data length is 32 bytes. Example : When the input data length for the first station is set to 23 bytes and that for the

second station to 7 bytes

(5) Communication trouble area

When some kind of trouble occurs during communication the AJ71PB92D/A1SJ71PB92D stores the contents of the trouble in this area. Fixed type or ring type can be selected for this area by turning the communication trouble area type selection (Y03) on or off (refer to Section 4.2.2 (9)). As shown in the following diagram, a total of 8 pieces of trouble information that consist of the trouble code, detailed data length, and detailed data can be stored in the basic configuration regardless of whether for fixed or ring data. Ring type data is stored in order from the header with the header always being the latest trouble information. With fixed type data, when 8 pieces of trouble information are stored the areas 2 to 8 (data 1 to 7) are fixed, so when the next new trouble occurs only header area 1 (data 8) is updated. All trouble information for either type can be cleared by turning on the communication trouble area clear request signal (Y02). When the communication trouble detection signal reset signal (Y01) is on, the contents of the communication trouble area are held though the communication trouble detection signal (X01) turns off. The communication trouble area is configured as shown below.

4.4 While-Run Operation M ode Changi ng Function

This function enables the operation mode of the AJ71PB92D/A1SJ71PB92D to be changed using the I/O signals X/Y and buffer memory, without resetting the CPU module. The following I/O signals and buffer memory are used.

(1) I/O signals (Refer to Section 4.2 for details)

X11: Operation mode change completion signal Y11: Operation mode change request signal

(2) Buffer memory (Refer to Section 4.3 for details)

Address 2254/8CEh: Current operation mode Address 2255/8CFh: Operation mode change request area Address 2256/8D0h: Operation mode change result area

Further, a new operation mode can be registered onto E

PROM built in the AJ71PB92D/A1SJ71PB92D by specifying it for the buffer memory. When the operation mode has been registered onto E

PROM by this function, the

AJ71PB92D/A1SJ71PB92D operates in the operation mode of E

PROM if the mode setting switch is preset to 0 (normal service mode), 1 (parameter setting mode) or E (extended service mode) at a system startup. However, when the mode setting switch is preset to 2 (self-diagnosis mode), the AJ71PB92D/A1SJ71PB92D operates in the self-diagnosis mode.

Change the operation mode in the following procedure. (1) Before changing the operation mode, turn off the exchange start request signal Y00 to stop

data exchange.

(2) Set the required operation mode in the "operation mode change request area" (address

2255/8CFh) of the buffer memory. (3) Turn on the operation mode change request signal Y11. (4) The AJ71PB92D/A1SJ71PB92D changes to the requested operation mode. (5) The AJ71PB92D/A1SJ71PB92D turns on the operation mode change completion signal X11. (6) As X11 has turned on, the "current operation mode" (address 2254/8CEh) and "operation

mode change result area" (address 2256/8D0h) of the buffer memory are read to confirm that

the operation mode has changed.

5.2 Handling Precautions

This section explains handling precautions for A1SJ71PB92D.

CAUTION

Do not touch the conductive area or the electronic parts of the module. Doing so may cause malfunctioning or breakdowns.

Switch all phases of the external power supply of the PLC 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 filling or wire chips get inside the module. These can cause fire, breakdowns and malfunctioning.

Never disassemble or modify the module. This may cause breakdowns, malfunctioning, 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.

Set the ON/OFF select switch of the terminal resistor before the operation. If the setting is switched during the operation, network error may occur, or error detection may not be performed by error.

Before handling the module, always touch a grounded metal to discharge the static electricity from the human body. A failure to do so can cause the module to fail or malfunction.

(1) The AJ71PB92D/A1SJ71PB92D’s case is made of resin, so be careful not to drop it or

strike it hard.

(2) The module fixing screw (M4) fastening torque should be tighten within the range of

78.4 to 117.6N·cm

5.5.3 Precautions against wiring

As one of the requirements to give full play to AJ71PB92D/A1SJ71PB92D’s functions and make up the system with high reliability, it is necessary to have an external wiring unsusceptible to an influence of noise. Precautions against external wiring of AJ71PB92D/A1SJ71PB92D is described below.

(1) Do not route the wire of AJ71PB92D/A1SJ71PB92D close to or bundle it together with the

main circuit and high-tension lines, or the load-carrying lines from other than the PLC. Otherwise, the module may be susceptible to an influence of noise and surge induction.

(2) Keep the wires from the input/output modules of the PLC away from the communication

cable as much as possible as shown below.

Point

In Fig. 6.1, the FROM/TO instruction and bus cycle time are drawn as if they are synchronous, but they are actually asynchronous. If the buffer memory data are overwritten by the TO instruction during the bus cycle time, the overwritten buffer memory values are transferred to the internal buffer at the next transfer time.

(2) If the network configuration allows the power supplies to the A1SJ71PB92D and to the slave

station to be on simultaneously, there may be cases in which the slave side is not completely started at the time the X1B turns on. In this case, consider the time lag for the slave station to completely start up when estimating the time period from the point the X1B turns on until the communication start "Y00" turns on.

Appendix 2 Precautions for Replacing AJ71PB92 with A(1S)J71PB92D

Pay attention to the following points when replacing the AJ71PB92 with the A(1S)J71PB92D.

(1) The sequence programs and cable wiring prepared for the AJ71PB92 can be used for the

A(1S)J71PB92D.

(2) The parameters for the AJ71PB92 cannot be used for the A(1S)J71PB92D due to a file format

difference.

Obtain the EN50170-compliant device definition file (GSD file) for your device from the device manufacturer, and re-create the parameters using MELSEC ProfiMap or GX Configurator-DP.

(3) The parameter setting software packages used for the AJ71PB92 are not available for the

A(1S)J71PB92D.

The parameter setting software packages differ between the AJ71PB92 and A(1S)J71PB92D as indicated in the following table.

(4) Though the switch setting of the AJ71PB92 was made with the rotary and DIP switches, that

of the A(1S)J71PB92D is made with the rotary switch only.

The switch setting differs between the AJ71PB92 and A(1S)J71PB92D as indicated in the following table.
