Due to the data point configuration in STEP 7, programming program blocks in order to transfer the process data is unnecessary. The individual data points are processed oneto-one in the control system.

●

The DNP3 CP can use the security functions specified in the DNP3 protocol and therefore secure communication in the DNP3 network, including the following:

– Secure authentication (SA) of the communications partner

The DNP3 CP checks whether the communications partner has the right to access the DNP3 CP.

Formation of the Message Authentication Code (MAC) using symmetrical (pre-shared key, PSK) or asymmetrical cryptography (public/private keys)

Use of IPsec for transferring the key

– Logging of security events: Successful and failed authentication, key exchange,

statistical counters

You enable the security functions in the STEP 7 configuration with the required options.

●

The essential features of IP configuration for the CP:

– The CP supports IP addresses according to IPv4 and IPv6.

– An IPv6 address can be used in addition to an IPv4 address.

– Address assignment:

The IP address, the subnet mask and the address of a gateway can be set manually in the configuration.

As an alternative, the IP address can be obtained from a DHCP server or by other means outside the configuration.

●

The CP can the have its local time of day synchronized by the partner (master) as UTC time.

The time of day can be read from the CPU. The mechanisms are described in the STEP 7 information system.

For information on the format of the time stamp, refer to the section Datapoint types (Page 35).

●

The CP can communicate with a redundant control system (master).

●

The CP can store events of different classes and transfer them together to the master.

●

The sending of data to the master can be triggered in two ways:

– At the request of the master

– Triggered by various selectable criteria

●

With configured events in the process image of the CPU, the CP can send messages as e-mails. The data of the events to be sent by e-mail are configured using PLC tags.

●

Analog values can be preprocessed on the CP according to various methods.

1.3 Configuration limits and performance data

●

From an engineering station (ES) on which STEP 7 is installed, you can use the online functions of STEP 7 via the CP to access the S7-1200 CPU if the station is located in the same IP subnet. The following online functions are available:

– Downloading project or program data from the STEP 7 project to the station

– Querying diagnostics data on the station

– Downloading firmware files to the CP

For a remote station located in a different IP subnet or that can be reached via the Internet, these functions can only be used if the ES is connected to the station via a VPN tunnel (for example via a SCALANCE S).

●

As an SNMP agent, the CP supports data queries using SNMP (Simple Network Management Protocol) in version V1.

For more detailed information, refer to section Communication types and SNMP (Page 42).

In each S7-1200 station, up to three CMs/CPs can be plugged in and configured; this means a maximum of three identical CP 1243-1 DNP3 or three identical CP 1243-1 IEC modules.

●

The CP can establish connections to up to 4 masters. These can be single or redundant masters.

In the case of 4 redundant masters, this would be 8 physical devices addressed using different IP addresses.

●

1 connection resource is reserved for online functions / TeleService.

●

8 connection resources for S7 connections (PUT/GET)

●

– 1 connection resource for PG connections

– 3 connection resources for OP connections

The maximum number of configurable data points is 200.

The data to be transferred by the CP is assigned to various data points in the STEP 7 configuration. The size of the user data per data point depends on the data type of the relevant data point.

With the DNP3 CP, contiguous memory areas can be transferred up to a size of 64 bytes using data point types of the object groups 110 (Octet String) and 111 (Octet String Event). You will find details in the information system of STEP 7 and in the section Datapoint types (Page 35).

The CP has a frame memory (send buffer) for data points configured as an event.

The send buffer has a maximum size of 64000 events divided into equal parts for all configured communications partners. The size of the frame memory can be set in STEP 7, refer to the section Communication with the CPU (Page 49).

You will find details of how the send buffer works (storing and sending events) as well as the options for transferring data in the section Types of transmission, event classes, triggers (Page 39).

Up to 10 messages can be configured in STEP 7 and sent as e-mails.

You will find a detailed overview of the attributes and properties specified in the DNP3 protocol and supported by the CP in the DNP3 device profile.

You will find the DNP3 device profile of the CP 1243-1 DNP3 on the Internet pages of Siemens Industry Online Support under the following entry ID:

The following example describes a configuration with a non-redundant control center in which all nodes are located in 1 IP subnet.

In this example, the DNP3 protocol is used; in other words, the stations are equipped with a CP 1243-1 DNP3.

A configuration in which the IEC protocol is used would have the same setup apart from the CP type (here CP 1243-1 IEC).

Figure 1-1 Configuration example with a non-redundant control center and stations in one IP subnet

The S7-1200 stations are connected to the Internet via the CP and connected to the control center.

When using the DNP3 protocol, for example, SIMATIC PCS 7 TeleControl or the system of a third-party provider can be used as the control center. If you use SIMATIC PCS 7 TeleControl as the DPN3 master in the control center, you require the necessary DPN3 driver.

The following example contains a configuration with a non-redundant control center.

In this example, the DNP3 protocol is used; in other words, the stations are equipped with a CP 1243-1 DNP3.

How to configure in STEP 7

5.3 Configuration in STEP 7

● You configure the master IP address as normal.

● When configuring the CP interface, configure the IP address of the SCALANCE S as a

router address.

● You create the VPN configurations with SCALANCE S both for the station end and for the control center end in STEP 7.

You configure the modules and networks in SIMATIC STEP 7. You will find the required version in the section Hardware requirements (Page 17).

You can configure a maximum of three CMs/CPs per station.

If you insert several CPs in an S7-1200, you can establish redundant communications paths. This is only possible if the control system supports redundant transmission paths to the same station.

Even with a single DNP3 CP or IEC CP, an S7-1200 can communicate with a redundant master.

The two devices of the redundant master are addressed by the CP using one DNP3 address or one IEC address but two different IP addresses.

Follow the steps below when configuring:

1. Create a STEP 7 project.

2. Insert the required SIMATIC stations.

Configuration of the master stations and connections neither possible nor necessary.

3. Insert the CPs and the required input and output modules in the stations.

4. Create an Ethernet network.

5. Connect the stations to the Ethernet subnet.

6. Configure the inserted CPs.

For details on configuring the communication, refer to the following section.

7. Save the project.

You will find more detailed information on configuring the CP in the Information system of STEP 7 and in the following sections.

5.4 Configuring datapoints and messages (e-mails)

One requirement for configuring communication between CP and control center is the programming of the assigned CPU and the input and output data of the station.

PLC tags must also be created to assign the user data to the data points.

For more detailed information, refer to the following sections.

When you load the station, the project data of the station including the configuration data of the CP is stored on the CPU.

You will find information on loading the station in the STEP 7 information system.

No program blocks need to be programmed for the CP to transfer user data between the station and communications partner. The data areas in the memory of the CPU intended for communication with the partner are configured data point-related on the CP. Each data point is linked to a PLC tag or a data block on the CPU.

PLC tags or DBs must first be created in the CPU program to allow configuration of the data points.

The PLC tags for data point configuration can be created in the standard tag table or in a user-defined tag table. All PLC tags intended to be used for data point configuration must have the attribute "Visible in HMI".

Address areas of the PLC tags are input, output or bit memory areas on the CPU.

Configuration limits and performance data (Page 12).

The formats and S7 data types of the PLC tags that are compatible with the protocol-specific data point types of the CP can be found in the section Datapoint types (Page 35).

This object group can be configured in the Data point editor of STEP 7 using the substitute object group 12. This object group can be configured in the Data point editor of STEP 7 using the substitute object group 20. This object group can be configured in the Data point editor of STEP 7 using the substitute object group 22. This object group can be configured in the Data point editor of STEP 7 using the substitute object group 41. With these data point types, contiguous memory areas up to a size of 64 bytes can be transferred. All S7 data types with

The initial data point types of the following object groups can be configured using the substitute object groups listed above:

● 10 [2]

● 11 [1, 2]

● 21 [1, 2, 5, 6]

● 23 [1, 2, 5, 6]

● 40 [1, 2, 3]

● 42 [1, 2, 4, 5, 6, 7, 8]

To configure the DNP3 CP, use the specified substitute object group.

Assign each data point on the master using the configurable data point index in STEP 7. The data point of the DNP3 CP is then assigned to the corresponding data point on the master.

Example of configuring the data point Binary Output (10 [2]) The data point is configured as follows: On the DNP3 CP as Binary Command (12 [1]) On the master as Binary Output (10 [2])

With the data point types Binary Output Event (11) and Analog Output Event (42) you also need to enable mirroring back, refer to the next section.

You first create the data point types Binary Output Event (object group 11) and Analog Output Event (object group 42) as described above as data points of the object groups 12 or

41.

The local values of these to object groups can be monitored for change and the changes transferred to the master (reporting changes).

Changing a local value can, for example, be caused by manual operator input on site.

To allow the value resulting from local events or interventions to be transferred to the master, the data point in question requires a channel for mirroring back.

This mirroring back function is enabled using the "Value monitoring (Reporting Changes)" option in the STEP 7 configuration, refer to the section "General" parameter group (Page 50).

Remember that to use the mirror back function, you need to interconnect the local values in the controller with the relevant PLC tag of the data point.

Time stamps are transferred in UTC format (48 bits) and contain milliseconds since

IEC CP time stamps are transferred according to the IEC specification in the "CP56Time2a" format. Note that in the frames only the first 3 bytes for milliseconds and minutes are transferred.

The cycle (including the pause) with which the CP scans the memory area of the CPU is made up of the following phases:

●

For data points of the type "Input", which are configured with the "High priority" setting in the data point configuration in "General > Priority in the scan cycle", the PLC tags are all read in one scan cycle.

●

In every cycle, the values of a certain number of unsolicited write jobs are written to the CPU. The number of tags written per cycle is specified for the CP in the "Communication with the CPU" parameter group with the "Max. number of write jobs" parameter. The tags whose number exceeds this value are then written in the next or one of the following cycles.

●

For data points of the type "Input", which are configured with the "Low priority" setting in the data point configuration in "General > Priority in the scan cycle", the values of a part of the PLC tags are read in every scan cycle.

The number of tags read per cycle is specified for the CP in the "Communication with the CPU" parameter group with the "Max. number of read jobs" parameter. The tags that exceed this value and can therefore not be read in one cycle are then read in the next or one of the following cycles.

●

This is the waiting time between two scan cycles. It is used to reserve adequate time for other processes that access the CPU via the backplane bus of the station.

Since no fixed time can be configured for the cycle and since the individual phases cannot be assigned a fixed number of objects, the duration of the scan cycle is variable and can change dynamically.

The values of data points are stored in the image memory of the CP and transferred only when queried by the master. Events are also stored in the send buffer and can be transferred unsolicited. All data points are therefore classified as follows:

●

Static values are entered in the image memory (process image of the CP).

●

The values of data points configured as an event are also entered in the image memory of the CP. The value of the event is sent unsolicited to the communications partner if this function is enabled by the master.

The values of events are also entered in the send buffer of the CP.

All the current values of the configured data points are stored in the image memory. New values of a data point overwrite the last stored value in the image memory.

The values are sent after being queried by the communications partner. Refer to "Transfer after call" in the section "Types of transmission".

The send buffer is the data buffer on the CP for storing the values of events. The send buffer has a maximum size of 64000 events. The configured number of events is divided equally among all configured and enabled communications partners. The "Data buffer size" parameter for the size of the send buffer is described in the section Communication with the CPU (Page 49).

The frame memory operates chronologically; in other words, the oldest frames are sent first (FIFO principle). When the maximum number of events is reached and the frames could not be sent, the oldest values are overwritten.

If a connection to a communications partner is interrupted, the values of the events are retained in the buffer. When the connection returns, the buffered frames are sent.

With the DNP3 CP, additional conditions for sending the events can be specified:

● A maximum number of events in the send buffer, configurable for each event class.

● A configurable maximum storage period for events in the send buffer.

This configuration of these conditions is described in the section Ethernet interface (X1) > Advanced options (Page 43).

Depending on your CP type, you have the following transmission types available:

●

The current value of the data point is entered in the image memory of the CP. New values of a data point overwrite the last stored value in the image memory.

After being called by the communications partner, the current value at the time is transferred.

●

The value is entered in the send buffer triggered as an event. If unsolicited transfer is enabled by the master, the value is transferred unsolicited.

You will find details of the event classes in the following sections.

The type of transmission is specified for each data point in the data point configuration in STEP 7 with the "Type of transmission" or "Event class" parameter.

The process data of the various event classes is handled as follows:

●

Each value change is entered in the send buffer in chronological order.

The evaluation of the classification (1 or 2) must be handled by the master.

●

Only the current value at the time the trigger condition was met is entered in the image memory and overwrites the last value stored there.

The process data of the various event classes is handled as follows:

●

Each value change is entered in the send buffer in chronological order.

●

Only the current value at the time the trigger condition was met is entered in the image memory and overwrites the last value stored there.

Various trigger types are available for event-driven transfer:

●

The value of the data point is transferred when this reaches a certain threshold. The threshold is calculated as the difference compared with the last stored value, refer to the section Threshold value trigger (Page 54).

●

The value of the data point is transferred at configurable intervals or at a specific time of day.

●

The value of the data point is transferred when a configurable trigger signal is fired. For the trigger signal, the edge change (0 → 1) of a trigger bit is evaluated that is set by the user program. When necessary, a separate trigger bit can be configured for each data point.

If the memory area of the trigger bit is in the bit memory or in a data block, the trigger bit is reset to zero when the data point is transferred.

The status IDs of the data points described in the section Communications services (Page 9) also cause event-driven transfer.

With data points that were configured as an event, a change in a status bit causes an event to be generated and therefore results in unsolicited transfer.

Example: If the status "RESTART" or "NT" of a data point configured as an event changes to "Value updated" when the station starts up, this causes the transfer of the value.

In the two following parameter groups, you enable the types of communication of the CP.

To minimize the risk of unauthorized access to the station via Ethernet, you need to enable the communications services that the CP will execute individually. You can enable all options but at least one option should be enabled.

●

Enables communication using the DNP3 protocol or the IEC protocol on the CP.

●

Enables access to the CPU for the online functions via the CP (diagnostics, loading project data etc.). If the function is enabled, the engineering station can access the CPU via the CP.

If the option is disabled, you have no access to the CPU via the CP with the online functions. Online diagnostics of the CPU with a direct connection to the interface of the CPU however remains possible.

●

Enables S7 communication on the CP.

If you configure S7 connections to the relevant station, and these run via the CP, you will need to enable this option.

●

Enables communication using SNMP on the CP.

SNMP is a protocol for managing networks. To transmit data, SNMP uses the connectionless UDP protocol.

The information on the properties of SNMPcompliant devices is entered in MIB files (MIB = Management Information Base).

The CP supports data queries using SNMP in version V1.

For the CP to support the object groups of the standard MIB-II:

● Supported object groups:

System, Interfaces, Address Translation (AT), IP, ICMP, TCP, UDP, SNMP

● Object groups not supported:

EGP, Transmission

Write access is permitted only for the following MIB objects of the "System" group:

● sysContact, sysLocation, sysName

A set sysName is sent as the host name using DHCP option 12 to the DHCP server to register with a DNS server.

For all other MIB objects and MIB object groups, only read access is possible for security reasons.

The CP does not support traps.

The CP uses the following community names to control the access rights in the SNMP agent:

The TCP connection monitoring time is set for all TCP connections of the CP in the parameter group of the Ethernet interface, see also the section Ethernet interface (X1) > Advanced options (Page 43). These settings apply to all TCP connections of the CP.

With the DNP3 CP, it is also possible to set the globally set TCP connection monitoring time separately for each individual partner:

●

The value set in the partner station of the DNP3 CP overwrites the global value for this partner that was set in the parameter group "Ethernet interface (X1) > Advanced options > TCP connection monitoring".

With the IEC CP, the monitoring time can only be set globally for the Ethernet interface and are not for each individual communications partner.

5.8 Notes on configuring individual functions

●

If the "Report partner status" function is enabled, the CP signals the status of the communication to the remote partner.

– Bit 0 of "PLC tag for partner status" (data type WORD) is set to 1 if the partner can be

reached.

– Bit 1 is set to 1 if all the paths to the remote partner are OK (useful with redundant

paths).

– Bit 2 indicates the status of the send buffer (frame memory).

The following values are possible:

- 0: send buffer OK

- 1: send buffer threatening to overflow (more than 80 % full).

- 3: send buffer has overflowed (fill level 100 % reached).

As soon as the fill level drops below 50%, bit 3 is reset to 0.

Bits 3 to 15 of the PLC tags are not used and do not need to be evaluated in the program.

Various levels of protocol conformity are defined in the DNP3 protocol and they describe the supported range of functions (subset) of a master or a station. These levels (implementation levels) are known as "DNP3 Application Layer protocol Level" and abbreviated with DNP3-L1 to DNP3-L4.

The selection of the level used by the DNP3 CP which must correspond to that of the connected master is set separately in STEP 7 for each individual communications partner (DNP3 master).

The CP supports the following implementation levels:

● DNP3-L1

● DNP3-L2

● DNP3-L3

● DNP3-L4

● DNP3-L5

The implementation level known here as DNP3L5 that is not specified in the standard contains the range of functions of DNP3L4 and in addition support of the following DNP3 data types / variations:

– 64-bit analog value as floating-point number without time of day

– 64-bit analog value as floating-point number with time of day

– Counter event with time of day in 16-bit format

5.8 Notes on configuring individual functions

If the security function is enabled, the DNP3 master and station (DNP3 CP) authenticate themselves with a secret key, the pre-shared key.

With the help of the common pre-shared key, after the first connection establishment between master and DNP3 CP, session keys are agreed that are then renewed cyclically. Renewal of the session keys is normally initiated by the master. The criteria for renewing the key are specified in the following parameters.

● Key exchange interval

● Authentication requests before key exchange

As soon as one of these conditions is met, the session key is renewed.

These and several other parameters are explained below.

●

Specifies the length of the pre-shared key in bytes.

Permitted range: 16 ... 128. Depending on the secure hash algorithm configured in STEP 7 above, the following lengths are preset:

– For SHA-1: 16

– For SHA-256: 32

The value 0 (zero) is not permitted.

●

Maximum number of requests of a master within the key exchange interval configured below. If the configured number of requests of the master is exceeded within the key exchange interval, the DNP3 CP enters a message in the diagnostics buffer of the CPU. Permitted range: 2 ... 255. Default setting: 5.

●

Maximum number of authentication requests of the DNP3 CP with the master. When this number is reached, the session key is renewed. The value 0 (zero) is not permitted.

Recommendation: Set the number for the DNP3 CP twice as high as for the master.

●

Exchange interval for the session key. When time set for this interval is reached, the session key is renewed.

If the key exchange interval is set to 0 (zero), the key is renegotiated according to the configured "Authentication requests before key exchange".

Recommendation: Set the key exchange interval for the DNP3 CP twice as high as for the master.

5.8 Notes on configuring individual functions

Exception: The value -32768 / 8000h as fault ID for wire break of live zero hardware analog inputs is transferred. With a software input, on the other hand, all values lower than zero are corrected to zero.

If mean value generation is active, this parameter has no effect.

Analog values that fluctuate quickly can be smoothed with this function.

The smoothing factors are calculated according to the following formula as with S7 analog input modules.

where y

= smoothed value in the current cycle

= value acquired in the current cycle n

k = smoothing factor

The following values can be configured for the module as the smoothing factor.

● 1 = No smoothing

● 4 = Weak smoothing

● 32 = Medium smoothing

● 64 = Strong smoothing

If mean value generation is active, this parameter has no effect.

An analog value in the overflow range (32767 / 7FFFh) or underflow range (-32768 / 8000h) is not transferred for the duration of the error suppression time. This also applies to live zero inputs. The value in the overflow/underflow range is only sent after the error suppression time has elapsed, if it is still pending.

If the value returns to the measuring range before the error suppression time elapses, the current value is transferred immediately.

A typical use case for this parameter is the suppression of peak current values when starting up powerful motors that would otherwise be signaled to the control center as a disruption.

The suppression is adjusted to analog values that are acquired by the S7 analog input modules as raw values. These modules return the specified values for the overflow or underflow range for all input ranges (also for live zero inputs).

If mean value generation is active, this parameter has no effect.

If the CPU makes preprocessed finished values available in bit memory or in a data block, suppression is only possible or useful if these finished values also adopt the values listed above 32767 / 7FFF

or -32768 / 8000h in the overflow or underflow range. If this is not the

case, the parameter should not be enabled for preprocessed values.

5.8 Notes on configuring individual functions

With this parameter, acquired analog values are transferred as mean values.

The current values of an analog data point are acquired cyclically and totaled. The number of acquired values per time unit depends on the read cycle of the CPU and the CPU scan cycle of the CP. The mean value is calculated from the accumulated values as soon as the transfer is triggered by a time trigger. Following this, the accumulation starts again so that the next mean value can be calculated.

The mean value can also be calculated if the transmission of the analog value message is triggered by a request from the communications partner. The duration of the mean value calculation period is then the time from the last transmission (for example triggered by the trigger) to the time of the request. Once again, the accumulation restarts so that the next mean value can be calculated.

If the acquired analog value is in the overflow range (32767 / 7FFF (-32768 / 8000

), this value can either be taken into account immediately in the calculation of

the mean value or it can be suppressed for a specific period for the calculation of the mean value. The required response can be decided with the Error suppression time parameter:

● Error suppression time = 0

Acquisition of a value in the overflow or underflow range results in the mean calculation being stopped immediately. The value 32767 / 7FFF invalid mean value for the current mean value calculation period and sent when the next analog value frame is triggered. The calculation of a new mean value is then started. If the analog value remains in the overflow or underflow range, this new value is again saved immediately as an invalid mean value and sent when the next frame is triggered.

● Error suppression time > 0

If you have configured an error suppression time and then enable mean value generation, the value of the error suppression time is grayed out but no longer used. If mean value generation is enabled, the error suppression time is set to 0 (zero) internally.

In these two input boxes, you set a limit value at the start of the measuring range and at the end of the measuring range and if these limits are violated, the transfer of a frame is triggered. Configuration of a threshold value trigger is necessary for this function.

The range of the value that can be configured as a decimal number corresponds to the measuring range of the analog module (-32768 ... 32767).

) or underflow range

or -32768 / 8000h is saved as an

By configuring these two values, you specify that the values of this analog value are transferred as a frame only in the following situations:

● When called up by the master

● When the threshold value trigger fires

● When the value of "Set start of measuring range" is exceeded

● When the value of "Set end of measuring range" is undershot

The parameters "Set start of measuring range" and Set end of measuring range" are pointless for measured values that have already been preprocessed in the CPU.

Note Evaluation of the value even when the option is disabled

If you enable one or both options and configure a value and then disable the option later, the grayed out value is nevertheless evaluated.

ng range" from the input boxes and then disable the relevant

If the analog value fluctuates quickly, it may be useful to smooth the analog value first if the "Set start of measuring range" and "Set end of measuring range" parameters are enabled. This avoids a frame being sent every time a limit value is violated if the analog value fluctuates close to one of the two limit values for a longer period of time.

The CP calculates the value for the threshold value trigger after the analog value preprocessing, refer to the section Threshold value trigger and Analog value preprocessing (Page 50).

To calculate the threshold value trigger, the integration method is used.

In the integration threshold value calculation, it is not the absolute value of the deviation of the process value from the last stored value that is evaluated but rather the integrated deviation.

The integration threshold value calculation works with a cyclic comparison of the integrated current value with the last stored value. The calculation cycle in which the two values are compared is 500 milliseconds. (Note: The calculation cycle must not be confused with the scan cycle of the CPU memory areas).

The deviations of the current process value are totaled in each calculation cycle. The trigger is set only when the totaled value reaches the configured value of the threshold value trigger and a new process value is entered in the send buffer.

The method is explained based on the following example in which a threshold value of 2.0 is configured.

5.8 Notes on configuring individual functions

Table 5- 4 Example of the integration calculation of a threshold value configured with 2.0

In this example, a value of 2.0 was configured for the threshold value trigger.

With the changes in the process value shown in the example, the threshold value trigger fires twice:

● At the time 3.5 s: The value of the integrated deviation is at 2.0. The new process value

● At the time 6.0 s: The value of the integrated deviation is at 2.1. The new process value

In this example, if a deviation of the process value of approximately 0.5 should fire the trigger, then with the behavior of the process value shown here a threshold value of approximately 1.5 ... 2.5 would need to be configured.

If important events occur, the CP can send e-mails to a communications partner.

You configure the e-mails in STEP 7 in the Data point and alarm configuration. You can find this using the project tree:

Project > directory of the relevant station > Local modules > CP 1243-1

stored in the send buffer is 20.5.

stored in the send buffer is 19.9.

No TCP/IP connection could be established to the SMTP server.

5.8 Notes on configuring individual functions

Remember the following requirements in the CP configuration for the transfer of e-mails:

● It is necessary to enable the CP-specific type of communication:

– DNP3: "Enable DNP3 protocol"

– IEC: "Activate telecontrol communication (IEC)"

● The parameter group "E-mail configuration" needs to be configured.

To do this, you require the following information:

– Access data of the SMTP server: Address, port number, user name, password

– Email address of the recipient

One of the following events triggers sending of the e-mail:

● CPU changes to STOP.

● CPU changes to RUN.

● The connection to the partner is interrupted.

● The connection to the communications partner is re-established.

● A trigger signal is fired.

For the trigger signal to send the e-mail, the edge change (0 → 1) of a trigger bit is evaluated that is set by the user program. When necessary, a separate trigger bit can be configured for each e-mail.

If the memory area of the trigger bit is in the bit memory or in a data block, the trigger bit is reset to zero when the e-mail is sent.

If this option is enabled in STEP 7, a status is output on the CP that provides information about the processing status of the sent e-mail. The status is written to a PLC tag of the type DWORD that is specified in the "External status" box.

The meaning of the statuses returned in hexadecimal format is as follows:
