CP data: Transferring - collecting - analyzing

Access to the analyzed data

Requirements for CP configuration

The CP is intended for operation in an S7-1200 automation system. The CP allows connection of the S7-1200 to Industrial Ethernet or via the Internet to a plant cloud in the operation center.

With the combination of different security functions such as firewall and protocols for data encryption, the CP protects the station and even entire automation cells from unauthorized access and protects the communication between the remote S7 station and the operation centerfrom espionage and manipulation.

To transfer data values of the CP regularly, e.g. diagnostics or maintenance data, to an operation center:

● Set up the Plant Cloud Communication to one or two operation centers.

To obtain a prediction of the status of your system or your devices:

● Have the transferred data analyzed using this remote computing center/server of the operation center.

To call up the analyzed data, you have the following options available:

● Direct access to the analyzed data.

● Within the framework of a service contract, you receive regular reports about the status of

your system or your devices.

Remember the following requirements in the CP configuration for Plant Cloud Communication:

● Activation of Plant Cloud Communication ("Communication types" parameter group).

● IP address assignment: Set the IP address manually or obtain the IP address from a

DHCP server.

●

The essential features of IP configuration for the CP:

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

For applications in IPv6 networks, an IPv6 address can be used in addition to an IPv4 address.

– IP 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.

●

– If Plant Cloud Communication is enabled, the CP can obtain its local time as UTC time

from the operation center or using NTP or NTP (secure). The time of day can be read from the CPU. For the communication with an operation center, give preference to the secure method NTP (secure). 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 33).

For more information, refer to the section Time-of-day synchronization (Page 40).

●

If a connection fails, the CP can buffer the data of events of different classes and transfer them bundled to the operation center.

●

The Plant Cloud Communication with the operation center is started in the following way:

– Triggered by various selectable criteria.

●

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

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. Online access via the operation center is not possible.

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.

●

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 SNMP (Page 41).

With Industrial Ethernet Security, individual devices, automation cells or network segments of an Ethernet network can be protected. The data transfer via the CP can be protected from the following attacks by a combination of different security measures:

● Data espionage

● Data manipulation

● Unauthorized access

Secure underlying networks can be operated via additional Ethernet/PROFINET interfaces of the CPU.

The CP supports the following security functions:

●

– IP firewall with stateful packet inspection (layer 3 and 4)

– Firewall also for "non-IP" Ethernet frames according to IEEE 802.3 (layer 2)

– Limitation of the transmission speed ("Bandwidth limitation")

– Global firewall rules

●

Secure communication with one or two operation centers.

●

To allow monitoring, events can be stored in log files that can be read out using the configuration tool or can be sent automatically to a Syslog server.

Note Number of PLC tags

Remember the maximum possible number of PLC tags the can be used for data point configuration in the section

Access to the memory areas of the CPU

5.4 Configuring data points and messages

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.

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 33).

The values of the PLC tags or DBs referenced by the data points are read and transferred to the communications partner by the CP.

Data received from the communications partner is written by the CP to the CPU via the PLC tags or DBs.

Duration of the CPU scan cycle

5.6 CPU scan cycle

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.

5.7 Types of transmission, event classes, triggers, status identifiers

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

●

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 64 000 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 47).

Data points that are not configured as an event ("Transfer after call") 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 operation center.

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

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.

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.

5.7 Types of transmission, event classes, triggers, status identifiers

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 as an event and transferred unsolicited to the communications partner when the trigger fires.

You will find details of the event classes and triggers 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.

●

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 starting 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 52).

●

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.

Note the range and application of the security functions of the CP, refer to the section Other services and properties (Page 11).

Each incoming or outgoing frame initially runs through the MAC firewall (layer 2). If the frame is discarded at this level, it will not be checked by the IP firewall (layer 3). This means that with suitable MAC firewall rules, IP communication can be restricted or blocked.

If you specify an address range for the source IP address in the advanced firewall settings of the CP, make sure that the notation is correct:

● Separate the two IP addresses only using a hyphen.

Correct: 192.168.10.0-192.168.10.255

● Do not enter any other characters between the two IP addresses.

Incorrect: 192.168.10.0 - 192.168.10.255

If you enter the range incorrectly, the firewall rule will not be used.

If the value for filtering the system events is set too high, you may not be able to achieve the maximum performance for the communication. The high number of output error messages can delay or prevent the processing of the communications connections.

In "Security > Log settings > Configure system events", set the "Level:" parameter to the value "3 (Error)" to ensure the reliable establishment of the communications connections.

A value is configured for the waiting time before the next connection establishment attempt.

With the value 0, the attempts until successful connection establishment are made as default at the following intervals: 3 x 60 s, 3 x 120 s, 4 x 900 s, 23 x 3 600 s (1 hour), 1 x 86 400 s (1 day).

●

If the "Report operation center status" function is enabled, the CP signals the status of the communication to the operation center.

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

operation center can be reached.

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

paths).

– Bits 2-3 indicate 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%, bits 2 and 3 are reset to 0.

Bits 4 to 15 of the PLC tags are not used and do not need to be evaluated in the program.

Depending on the data point type, the functions for analog value preprocessing described below are supported.

If unipolar transfer is enabled, negative values of analog inputs are corrected to zero.

Exception: The value -32768 / 8000 inputs is transferred. With a software input, on the other hand, all values lower than zero are corrected to zero.

Mean value generation

5.11 STEP 7 configuration of individual parameters

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

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

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 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.

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).

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 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.

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

Threshold value trigger: How the integrattion calculation works

The calculation cycle

5.11 STEP 7 configuration of individual parameters

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 48).

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 amount of 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.

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

0.5 20.3 +0.3 0.3

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, if the value 2.0 is reached:

● At the time 3.5 s: The value of the integrated deviation is at 2.0. The new process value stored in the send buffer is 20.5.

● At the time 6.0 s: The value of the integrated deviation is at 2.1. The new process value stored in the send buffer is 19.9.

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.
