Description From STEP 7 V5.0 SP3 HF3 onwards you can reach ST stations online over and beyond subnet limits with the PG/PC, in order, for example, to load user programs or a hardware configuration or in order to execute test and diagnostic functions. You can connect a PG/PC at any place within the network and connect online to any stations which are reached through gateways.
Gateway
The gateway from a subnet to one or more other subnets is in a SIMATIC station that has interfaces to the subnets concerned.
Requirements
At least STEP 7 V5.0 SP3 HF3 is installed on the PG/PC for configuration and use of the S7 routing function.
An interface (Industrial Ethernet or PROFIBUS PC CP) is installed in the PG/PC to establish a connection to the gateway. You can use PROFIBUS PC CPs 55xx and 56xx. You can use any NDIS-compatible Ethernet network card (3COM, CP1613, for example) as Industrial Ethernet interface in the PG/PC.
The associated communications modules of the station support the S7 routing function.
The network configuration does not go across project boundaries.
Both the modules and the PG or PC are loaded with the configuration information that contains the latest "knowledge" about the complete network configuration of the project. Technical background All the modules associated with the gateway must receive information about which subnets can be reached over which routes (= routing information).
Note The lists below have been updated with the modules of the hardware catalog of STEP 7 V5.4 SP2. This means that older modules which support the S7 routing function are listed in the tables, but are not necessarily included in the hardware catalog of the latest versions of STEP 7.

Use the PB FC Standard Cable IS GP (order number: 6XV1831-2A) and the PROFIBUS connector 6ES7 972-0DA60-0XA0 to connect the ET 200iSP intrinsically safe remote I/O system to the PROFIBUS network.
The IK PI catalog ("PROFIBUS" chapter) contains the technical data, order data and the order numbers of other PROFIBUS bus cables and bus connectors.
Warning
In order to set up an intrinsically safe PROFIBUS segment, it is imperative to use the RS 485-IS coupler.
The manual for the RS 485-IS coupler is available in Entry ID 29306413.
What are the system limits in an F CPU for safe bidirectional data communication via S7 Communication?
Description: This entry gives you an overview of the system limits of S7 Communication.
The following figures show the basic configuration of S7 Communication between F CPUs via Industrial Ethernet. Bidirectional data communication is via an S7 connection.
Fig. 01
Alternatively, bidirectional data communication can be via two separate S7 connections. In this way, you can structurally separate the send and receive channels, for example.
Fig. 02
The system limit of S7 Communication is determined by the following parameters:
Max. number of connections supported by the CPU.
Max. number of S7 connections that can be configured per interface.
Max. number of instances supported by the CPU.
Max. number of connections supported by the CPU The following table shows the maximum number of connections supported by the F CPUs.

Example: In a CPU 319F-3 PN/DP, you select S7 Communication via TCP/IP for safe bidirectional data communication. Depending on whether the data communication is via one or two configured S7 connections, you can configure another 15 or 14 S7 connections.
The fail-safe communication blocks "F_SENDS7" and "F_RCVS7" are called in the CPU user program for safe bidirectional data communication via S7 connections. These blocks internally call the system function blocks SFB8 "USEND" and SFB9 "URCV" respectively. In this way, the user data and associated acknowledgments are sent and received. An instance data block is assigned to each SFB8 "USEND" and SFB9 "URCV" system function block. Thus, the number of instance data blocks (= instances) is identical to the number of communication jobs.
This means that in the case of safe bidirectional data communication, at least four communication jobs are executed and four instances are needed. In this case, with the CPU 319F-3 PN/DP there remain 28 free instances.
In the user program of the CPU 319F-3 PN/DP, you can call a maximum of 16 fail-safe communication blocks "F_SENDS7" or F_RCVS7", because the maximum of instances is limited to 32.
In the case of safe bidirectional data communication, the CPU 319F-3 PN/DP can communicate with a maximum of 8 F CPUs.
Calculation for safe bidirectional data communication in the CPU 319F-3 PN/DP: 8 "F_SENDS7" + 8 "F_RCVS7" = 16 fail-safe communication blocks
8*("USEND" + "URCV") + 8*("USEND" + "URCV")
= 16 "USEND" + 16 "URCV" = 32 communication jobs or instances
Note: The safety function is foremost with F CPUs. Therefore, the system limit of S7 Communication is determined not only by the number of communication connections, but also by the response times achieved. If the required response times are not achieved because of the number of communication connections, the remedy is to
Reduce the number of communication connections.
Use a larger and faster CPU.
Which SIMATIC S7 components and which drives support clock-synchronicity functionality?
Configuration notes: Clock synchronicity is used to establish a direct connection between the equidistant DP cycle, the I/O modules and the user program.
The following SIMATIC components support clock-synchronicity functionality:
S7-300 CPUs
CPU 315 and CPU317 as DP masters from FW 2.5
CPU 319 as DP masters from FW2.4
S7-400 standard and S7-400F CPUs as DP masters from FW 3.1
ET 200M with selected modules
ET 200S with selected modules
Repeaters and diagnostics repeaters
Please note that only the internal DP interfaces on the CPUs can be used for clock-synchronicity communication.
STEP 7 V5.2 or higher is required for configuration purposes.
The drives which support the clock-synchronicity functionality are the entire product group comprising "SIMODRIVE 611U", "SINAMICS" and "MASTERDRIVE MC".
The following are required in order to configure the drives: Drive ES Basic V5.2 or higher, STEP 7 V5.2 or higher and one of the CPUs mentioned above.
You can find a list with the precise designations of the SIMATIC modules, which support clock-synchronicity functionality, in the manual SIMATIC Clock Synchronicity in subsection 2.2.1 of Entry ID 15218045

ET 200S: Are there special requirements for ET200S when mounted on sheet metal plates?
Request : Are there special requirements for ET 200S when
mounted on sheet metal plates?
May standard mounting plates and DIN rails (mounting rails) be used? Are
yellow passivated sheet metal plates permitted?
Suggestion : There is no special requirements regarding surface or
material of mounting plates and DIN rails. Our factory does not use yellow
passivated steel plates anymore due to hazardous substances beeing emitted
during passivation process.
The only requirement for the mounting rail is a fixing screw at every 200 mm
for stability reasons.
ET200S: How many motor starters can be allocated to a power module?
Request : What is the criteria in an application of power
modules with regard to amount of motor starters and distribution of
potential?
Suggestion : A power mudule serves to supply load power to motor
starters.
It is possible to configure load groups and potential groups.
A potential group always requires its own power module.
One power module can be used for several load groups with a rated current of
max. 40 A each (at common potential)
From the electrical point of view, up to 20 motor feeders can be allocated to
one power modul.
A total maximum physical length of 100 cm of an ET200S station is permitted.

A total maximum physical length of 100 cm of an ET200S station is permitted.
Request : ET 200S: How many load feeders may be
connected? What must be observed?
Suggestion : The maximum amount of load feeders depends on the total
current per load group/ potential group and the maximum bus length.
The maximum total current per group is 40 A, the maximum bus length of an
ET200S station is 100 m.
The space requirements of all other modules (interface-, electronic-, power-,
distance modules, etc.) must be taken into consideration.
Are more feeders required as possible acc. to the above, one more ET200S
station must be used. A multi-tier installation is not possible at the
moment.
At vertical mounting, simultaneity factor, ambient temperature and load must
be observed. Important is the maximum bus length of 100 m.
DOL starters for one direction of rotation and reversing starters may be
mixed.
Calculating the maximum absolute error of the counter module 1Count24V/100kHz (6ES7 138-4DA02-0AB0) when measuring rotational speed
QUESTION: How can you calculate the maximum absolute error of the counter
module 1Count24V/100kHz (6ES7 138-4DA02-0AB0) when measuring
rotational speed?
ANSWER: If the information in the manual about the error when measuring
rotational speed is not sufficient for your purposes, you can use
the following formula to calculate the maximum absolute error:
Example:
Implementation of SIMATIC modules of the product families S7-300, S7-400, ET 200M, ET 200S ET, 200iSP and TDC in environments with high concentrations of corrosive gas
are also approved for implementation in environments with high concentrations of corrosive gas in compliance with ISA–S71.04 severity level G1; G2; G3.
The relevant information is given in the manuals of the product families S7-300, S7-400, ET 200M, ET 200S, ET 200iSP and TDC.
Please refer to the relevant manuals for more information on climatic environmental conditions.
QUESTION:
Which PROFIBUS DP baud rates can I use for the communication to my
ET200S FO module?
ANSWER:
The module supports the following baud rates:
12 Mbit/s
1.5 Mbit/s
500 Kbit/s
187 Kbit/s
93.7 Kbit/s
19.2 Kbit/s
9.6 Kbit/s
If you try to set a different baud rate, then in STEP 7
V5.2 you get the error message shown in Fig. 1.
Fig 1: Error message in STEP 7 V5.2
Important:
In STEP 7 V5.1 it is also possible to set transmission rates
of 3 Mbit/s and 6 Mbit/s. But these baud rates are not suitable for
secure communications.
QUESTION:
Can a digital output module with a nominal current of e.g. 0,5A be
loaded in the range of the threshold value of the short circuit
protection (0,7 to 1,8A)?
ANSWER:
Power monitoring is done thermic. The reached value - except for
the circuit allowance - depends on the slope control speed and the
temperature, which increases rapidly for a power supply of more
than 0.5A. The module can only temporarily be loaded with an slope
increase between 0.5 to about 1.7A without activating the thermal
monitoring.
Note: While activating the thermal monitoring the module will not be
damaged.
QUESTION:
What is the minimum distance to be kept to the front door when
mounting an ET 200S in a control cabinet?
ANSWER:
There is no minimum distance specified, for example for heat
dissipation. However, a distance of about 2mm should be kept to
accommodate any tolerances in the components which might prevent
the front door of the control cabinet from closing properly.
Note:
Please pay attention to the different sizes of the various ET200S
modules.
Principle: According to the Seebeck effect, when two different metals are combined there is touch voltage at the points of contact, which depends on the temperature.
The thermo material combinations are standardized. The different material properties of a thermocouple determine the different application cases. The following table shows the assignment of thermocouple types to the various material compositions:

How long does the input signal have to be present before an analog input module identifies this signal as a process alarm?
Instructions This value is dependent on the conversion time, the type of measurement (current, voltage and resistance measurement) and the number of active channels.
The total conversion time determined (basic conversion time + additional conversion times) for a channel has to be multiplied by the number of active channels. This gives you the cycle time for a module. A signal must be present for at least this time to ensure that it is recognized as a process alarm.
The following manuals give information on the length of the basic conversion times of the various modules and on any additional conversion times that might have to be taken into account

If smoothing of the input signals has also been configured, the smoothing level which has been parameterized has to be taken into account. The smoothing levels (weak, medium and strong) are multiples of the cycle time and vary depending on the module used.
The smoothing level attenuates the rise of an input signal. The specification in cycles indicates in how many cycles an input signal with 63% of its maximum value is recognized
Note
Refer to the manuals listed above to find out the number of cycles per smoothing level for your module.
