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 
 

Modules	Manual	Entry ID
ET200M	SIMATIC S7-300 programmable logic controller, module data	8859629
ET200S	SIMATIC ET 200S distributed I/O system	1144348
ET 200iSP	SIMATIC ET 200iSP distributed I/O device	28930789
ET 200pro	SIMATIC ET 200pro distributed IO system	21210852
ET 200eco PN	SIMATIC ET 200eco PN distributed I/O device	29999018

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.

Description
You can operate an ET200 CPU or an S7 CPU as PROFINET I device (intelligent IO device). The following holds here:

• An S7-300 CPU can be used as an I device as from firmware version V3.2.0.
• An S7-400 CPU can be used as an I device as from firmware version V6.0.0.
• An ET200S or an ET200pro CPU can be used as an I device as from firmware version V3.2.0.
• You need at least STEP 7 V5.5 for the configuration.

Note
More information about the PROFINET I-device function is available in the system manual "PROFINET, System Description" in the chapter entitled "I Device" in Entry ID 19292127.

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.

Configuration Notes:
The protection rating indicates how suitable electrical equipment (e.g. devices, lighting, installation material) is for various environmental conditions and also the protection for people against potential dangers when using the equipment.

With regard to suitability for various environments, the systems are divided into relevant IP codes (Ingress Protection codes).

The protection rating is always indicated by the letters IP followed by two digits.
The first digit indicates the degree of protection against contact and solid foreign objects.
The table below explains the meanings of the first digits of the IP code.
 

Digit	Protection against body contact	Protection against solid foreign objects
0	No protection	No protection
1	Protected against large parts of the body (diameter 50mm)	Large solid foreign objects (diameter 50mm and greater)
2	Finger protection (diameter 12mm)	Medium-size solid foreign objects (diameter 12.5mm and greater, and length up to 80mm)
3	Tools and wires (diameter 2.5mm and greater)	Small solid foreign objects (diameter 2.5mm and greater)
4	Tools, wire, and small wires (diameter 1mm and greater)	Granular solid foreign objects (diameter 1mm and greater)
5 (K)	Wire protection (as IP4), dust-protected	Dust deposit (not harmful)
6 (K)	Wire protection (as IP4), dust-tight	No ingress of dust

The second digit indicates the degree of protection against liquids.
The table below explains the meanings of the second digits of the IP code.
 

Digit	Protection against liquids
0	No protection
1	Protected against vertically falling drops of water
2	Protected against direct sprays of water up to 15° from the vertical
3	Protected against direct sprays of water up to 60° from the vertical
4	Protected against water sprayed from all directions, limited ingress permitted
4k	Protection against water sprayed from all directions under increased pressure, applies only to road vehicles
5	Protected against low pressure jets of water from all directions
6	Protected against heavy seas or powerful water jets (flooding)
6k	Protected against powerful water jets under increased pressure (flooding), applies only to road vehicles
7	Protected against the effects of temporary immersion in water
8	Protected against the effects of continuous immersion in water
9k	Protection against high-pressure/steam-jet cleaning, applies only to road vehicles

Note:
Each protection rating is to be considered separately. A high protection rating does not automatically include a lower protection rating.
