Precautions for using the MELSEC-Q series Ethernet interface module

[Design Precautions]

!

WARNING

 For the operating status of each station after a communication failure, refer to relevant manuals

for the network. Erroneous outputs and malfunctions may lead to accidents. Not doing so can cause an accident due to false output or malfunction.

 To prevent the malfunction of the programmable controller system due to harmful e-mails, take

preventive measures (such as antivirus measures) so that the mail server for this module does not receive harmful e-mails.

 To maintain the safety of the programmable controller system against unauthorized access from

external devices via the Internet, take appropriate measures.

 When connecting a peripheral with the CPU module or connecting an external device, such as a

personal computer, with an intelligent function module to modify data of a running programmable controller, configure an interlock circuit in the program to ensure that the entire system will always operate safely. For other forms of control (such as program modification or operating status change) of a running programmable controller, read the relevant manuals carefully and ensure that the operation is safe before proceeding. Especially, when a remote programmable controller is controlled by an external device, immediate action cannot be taken if a problem occurs in the programmable controller due to a communication failure. To prevent this, configure an interlock circuit in the program, and determine corrective actions to be taken between the external device and CPU module in case of a communication failure.

 Do not write any data to the "system area" of the buffer memory in the intelligent function

module. Also, do not use any "use prohibited" signals as an output signal from the programmable controller CPU to the intelligent function module. Doing so may cause malfunction of the programmable controller system.

A - 2 A - 2

[Design Precautions]

!

CAUTION

 Do not bundle the control wires and the communication cables with the main circuit and the

power wires, and do not install them close to each other. They should be installed at least 100 mm (3.94 in.) away from each other. Failure to do so may generate noise that may cause malfunctions.

 When changing the operating status of the programmable controller CPU (such as remote

RUN/STOP) from the external device, select "Always wait for OPEN (Communication possible at STOP time)" for the "Initial timing" setting in the network parameter. The communication line will be closed when "Do not wait for OPEN (Communications impossible at STOP time)" is selected and the remote STOP is executed from the external device. Consequently, the programmable controller CPU cannot reopen the communication line, and the external device cannot execute the remote RUN.

[Installation Precautions]

!

WARNING

2) Checks whether the monitoring information read and the news conditions set by the user match. (Checks match/mismatch of the news conditions.)

3) Sends an e-mail when the monitored values match with the news conditions.

Multiple news conditions may be set so that an e-mail can be sent

(notified) when any of the conditions matches. (See Section 2.9.1.) Set the CPU inquiry time interval used by the Ethernet module to monitor the programmable controller CPU, considering the interval of change time in the monitoring target. After a news condition match occurs, the Ethernet module must confirm the mismatches of other news conditions for the same monitoring target. The next e-mail can be sent only after the Ethernet module confirms the mismatches of these news conditions.

4) The Subject of e-mail, which is sent when the notification conditions match, is fixed data. The format of the Subject is as follows (see Section 2.9.2):

• When monitoring the CPU status

Subject = "No. of transmissions (

1), CPU model name, Status,

Detection time"

• When monitoring the CPU device

Subject = "No. of transmissions (

1), Matched condition device,

Monitoring value... "

1 This is the number automatically added each time an Ethernet module sends

an e-mail. The numbers are counted up from 1. When the number reaches 4294967296, the number is cleared to 0. Then the numbers are counted up from 0 again to 4294967296.

POINT

The e-mail transmission function of the programmable controller CPU and the communication function using the random access buffer can be used together.

2.3 Precautions for Using the E-mail Function

The following explains precautions when using the e-mail function of the Ethernet module.

(1) Precautions regarding the system

(a) Design the system so that the entire system operates normally at all times

when sending/receiving e-mails to/from a running system and controlling the programmable controller.

(b) In order to avoid programmable controller system malfunctions caused by

receptions of illegal e-mails from the outside sources, take precautions in preventing illegal e-mails from being received on the mail served on the Ethernet module side (using an anti-virus program, etc).

(2) Precautions regarding the external device

(a) E-mails can be sent to programmable controller CPU stations with Q series

Ethernet modules connected. Note that A/QnA series Ethernet modules do not have the e-mail function; therefore, e-mails cannot be sent to programmable controller CPU stations.

(b) To send files to the Ethernet module as attachments to e-mail, specify the

encoding method (Base 64/7 bits/8 bits/Quoted Printable) of the attached files.

(3) Common precautions

(a) The Ethernet module stores the data of attached files received from the

external device in the device specified by the MRECV instruction without converting it from ASCII to binary.

(b) The maximum sizes of data that can be sent/received by the Ethernet

module are as follows:

• Data size of attached files: Up to 6k words

• Data size of main text: Up to 960 words

(c) Mails that are sent and received do not support encrypted data, compressed

data, and data conversion.

(d) When the external device could not be found in an e-mail sending from the

Ethernet module, the error code can be checked through the reception processing with the MRECV instruction.

If an external device cannot be found when sending e-mail using the

MSEND instruction, failure of e-mail transmission may not be recognized, depending on the operation of the mail server. Be sure to verify the receiver's e-mail address in advance.

Error codes are stored within the control data of the MRECV instruction.

(For details on error codes, refer to the User’s Manual (Basic).)

(e) The e-mail function is supported for the SMTP and POP3 servers.

MELSEC-Q/L

2 - 6 2 - 6

2 USING THE E-MAIL FUNCTION

(f) When communication errors of e-mails cannot be checked by a dedicated

instruction, check the error codes stored in the mail send/reception error log area of the buffer memory.

(g) If e-mails cannot be received, try one of the following.

1) Execute the MRECV instruction once.

2) Shorten the "Enquiry Interval" time in the e-mail settings of a programming tool.

3) Check the number of incoming mails remaining on the mail server. (Can be checked with the buffer memory address 5870

(h) When the receive data of an e-mail sent using the MSEND instruction is

abnormal (garbled characters, etc.), review the transmission data format (binary/ASCII/CSV) designated with the MSEND instruction.

The Subject should be designated in ASCII code data. (It is not converted to ASCII format.)

(i) Confirm with a system administrator regarding the minimum time intervals for

accessing the mail server when sending mails, reading receive mails, and inquiring whether or not there are receive mails. Depending on the mail server's security setting, frequent access may be prohibited.

(j) The e-mail send/reception function using the programmable controller CPU

and the communication function using the random access buffer cannot be used together. Only one of them can be used at a time.

The e-mail send function using programmable controller CPU monitoring

and the communication function using the random access buffer can be used together.

(k) A Subject that has been sent by the MSEND instruction from an Ethernet

module of the following versions, cannot be received normally by the MRECV instruction.

• Ethernet modules with serial numbers where the first 5 digits are 03101

or less Different methods are used for converting Subject data at send and reception. (See Section 2.1.1 (2).)

• When sending: Encodes the Subject and then send it.

1) Password: Designate the mail password of the local station's Ethernet module.

2) Mail address: Designate the mail address of the local station's Ethernet module.

3) Check receive mails: Select whether or not to check if receive mails have arrived and set the checking time interval when incoming mails are checked. When receive mail check is designated, set the time interval for inquiring the mail server whether or not there are mails addressed to the user.

The following table shows each setting range of the inquiry time intervals for checking receive mails. (30 s to 24 h)

Time units Setting range (default: 5 min)

h 1 to 24

min 1 to 1440

s 30 to 3600

POINT

If the inquiry time interval from the programmable controller CPU or other module to the server is short because of the POP3 server specifications, access may be restricted (lock status) on the server side. Check the POP3 server specifications, and set the inquiry time interval accordingly. (It is recommended to set the setting value of the inquiry time interval to the default (5 minutes) or more.)

(b) Mail server name

Set the Internet service provider and the domain name or IP addresses of the mail servers designated by the system administrator, used by the local station's Ethernet module.

1) Designate the domain name of the mail server.

2) Select the input format (decimal/hexadecimal) of the IP addresses.

3) Set the IP address of the outgoing mail server (SMTP).

4) Set the IP address of the incoming mail server (POP3).

POINT

• The SMTP server delivers (transfers) e-mails between mail servers.

• The POP3 server transfers received e-mails addressed to users to the corresponding users.

• The mail server names must be designated to use the e-mail function. (See POINT of (1).)

(a) Overview of automatic response system

1) The automatic response system differs from the other convert format in that designations can only be made when the Ethernet module installed station is the communication request destination station or communication relay receiving station.

2) The partner station IP Address or port number setting are not necessary with this conversion method; therefore, relay communications via other networks can be performed easily.

1) When the Ethernet module receives other station access

communication request message (command frame) from the CCLink IE Controller Network, CC-Link IE Field Network, MELSECNET/H, MELSECNET/10 relay communication function, the send source Network No., IP address, and UDP port number in the request message, are stored internally. The response message (response) for the communication request message is returned to the destination IP address and UDP port number calculated from the stored Network No. and station number. Therefore, by receiving the other station access communication request message first, the communication partner stations can be maintained.

2) The maximum number of station information that can be set is 64.

When more than 64 other station access communication request message is received, the Ethernet module starts deleting from the oldest data to store the station information in the newly received message communication request message. However, it is ignored if the station information is the same as the station information already stored.

Information from the same station is not stored twice.

(2) IP address computation system

(a) Overview of the IP address computation system

During calculation, the IP address of the partner station is obtained from the calculation equation below according to the Network No. and station number, and the UDP port number predefined for the Ethernet module system is used as the UDP port number of the destination.

For more information about the net mask pattern for routing other

networks, see Section 3.3.2.

(b) Conversion processing of the IP address computation system

1) When a communication request message (command frame) to access other station is received, the IP address is calculated from the Network No. and station number of the destination in the communication request message, and the communication request message is sent to the next station.

1 The Network No. and station number of the destination in the

communication request message are stored in the Ethernet module.

2) The response message (response) for the communication request message is returned based on the return IP address and the stored data above.

(3) Table exchange system

(a) Overview of the table exchange system

1) This method uses the Network No., station number, and IP address set in the conversion table of the Station No. <-> IP information, and uses the UDP port number predefined for the Ethernet module system as the UDP port number of the destination.

2) If duplicate network and station numbers are set in the conversion table, the data set with the younger registration number is used.

If all the required values are not set, communication may not be

performed successfully.

(b) Conversion processing of the table exchange system

1) When a communication request message (command frame) to access other station is received, the same Network No. and station number are searched in the conversion table of the Station No. <-> IP information, and the communication request message is sent to the partner station with the corresponding IP address.

2) The response message (response) for the communication request message is returned based on the return IP address and the data in the conversion table above.

3.4 Procedure for Accessing Other Stations

This section explains the procedure for accessing other stations via the Ethernet using the CC-Link IE Controller Network, CC-Link IE Field Network, MELSECNET/H, MELSECNET/10 relay communication function as well as the required processing.

(1) Setting the parameters

The parameters shown in Section 3.3 must be set using a programming tool.

(2) Accessing other stations

Access to other stations is performed from an external device/local station Q/LCPU using the CC-Link IE Controller Network, CC-Link IE Field Network, MELSECNET/H, MELSECNET/10 relay communication function.

REMARKS

• Access to other stations with the CC-Link IE Controller Network, CC-Link IE Field Network, MELSECNET/H, MELSECNET/10 relay communication function is performed using the UDP/IP protocol and data is always communicated in binary code.

• In the data communication, the port number (for the UDP/IP port) for the Ethernet module system is used.

• It is possible to continue accessing other stations while the initial normal completion signal (X19) is on. When the initial normal completion signal (X19) is turned off, the Ethernet module forcefully closes the connection although other station is being accessed.

(3) End processing of the Ethernet module

When ending access to other station with the CC-Link IE Controller Network, CCink IE Field Network, MELSECNET/H, MELSECNET/10 relay communication function that has been made using a connection opened by user, execute the close processing of the connection by seeing the User's Manual (Basic). When the following two functions are used to access other station, the close processing is not required.

This chapter describes how to use data link instructions for data communications between a Q/LCPU in the local station and a programmable controller CPU in another station using an Ethernet module via Ethernet or a network module.

POINT

When accessing other stations using data link instructions via Ethernet module, set the parameters shown in Chapter 3.

4.1 Access to Other Stations with the Data Link Instruction

The data link instruction is an instruction for a Q/LCPU to send/receive data, read/write data from/to the word device memory, and access other stations (such as remote RUN/STOP) with a Q/LCPU in other stations connected to other networks or Ethernet. If the initial processing of the local station, relay station, and access station's Ethernet module is finished correctly, it will be possible to access other stations by the data link instruction.

(2) Setting the arrival monitoring time of the control data storage

device

When the setting unit of arrival monitoring time is "1s", set a value greater than or equal to the TCP resend timer value set in the initial processing parameter for the arrival monitoring time designation area of the control data storage device. When the monitoring time is equal to or less than the TCP resend timer value, the TCP resend timer value is set as the arrival monitoring time. ( (When the setting value is less than or equal to the TCP resend timer value, the arrival monitoring timer equals the TCP resend timer value.)

1 Although the units of setting values for the TCP resend timer (setting value

units: 0.5 s) and the arrival monitoring timer (setting value units: s) are different, the TCP resend timer value is used as is.

(3) Checking the execution result of each data link instruction

The execution result (completion status) of each data link instruction is stored in the areas shown as binary values. After the execution of an instruction is completed, read the execution result from the storage area and verify either normal or abnormal completion.

Stored value at normal completion

4.3 Using the Data Link Instructions

This section explains how to use the data link instructions when accessing other stations via the Ethernet module.

(1) SEND instruction

1) When performing simultaneous other station accesses from multiple communication request source stations to the same communication request destination station, change the channel number of the communication request destination station for each communication request source station. If the channel number is being used at the communication request source station (being accessed from other station using the same channel number) when other station is accessed, the data link instruction ends in error. So, re-execute the instruction.

If the channel number used is different at the communication request

destination station side, simultaneous other station access can be performed from a maximum of eight communication request source stations to the same station.

2) When performing other station access from the same communication request source station to the same communication request destination station, change the channel number at the communication request destination station side. When designating the same channel number on the communication request destination station side, perform the second other station access after the first other station access is complete. If the second SEND instruction is executed before the first SEND instruction is completed, the SEND instruction ends in error.

(2) Instruction other than the SEND instruction

1) When simultaneous other station access is performed to the same communication request destination station from multiple communication request source station, and a busy error (being accessed from other station) occurs, re-execute the instruction.

2) When accessing other station from the same communication request source station to the same communication request destination station, execute the second data link command after other station access by the first data link instruction is complete.

(3) Broadcast (Simultaneous broadcast)

When FFH is designated as the target station number in the control data when executing SEND/WRITE (SWRITE)/REQ on the Ethernet, the command is sent to all external devices on the network.

(4) Interlock when executing the data link instruction

(a) Via Ethernet

Execute the data link command when the local station (communication

request source station) Ethernet module is at the following I/O sign

X19 X1F

SEND

X19: Initial normal complation signal X1F: Watchdog time error station signal

(b) Via other networks

Check the status of the local station (communication request source station), communication relay station, and access destination (communication request destination station) using the following devices. Execute the data link instruction if the status is normal.

• Link special relay: SB20, SB47, SB70, etc.

• Link special register: SW70 to 73, SW74 to 77, etc. See the reference manual for each network for the interlock signals, link

data send/receive processing, and processing time when performing data communication with the programmable controller CPU of another station via other networks.

(5) Specifying the number of times to resend the data link instructions

When executing each data link instruction except for ZNRD and ZNWR, it is recommended to designate a value greater than "1" for the number of resend designation area of the control data storage device. The resend timing when the READ command is executed after designating the number of resend is described below.
